Group of inventions relates to the processing of refractory gold-arsenic ores, in particular antimony sulfide ores and concentrates. There is a method for processing refractory gold-bearing arsenic and sulphide of arsenic ores and concentrates, including oxidative roasting followed by cyanidation of the candle (Malinetskii I.N., Metals precious metals), metallurgy, 1972, s). The disadvantage of this method are significant losses of noble metals from the tailings cyanide and education when firing large amounts of environmentally hazardous exhaust gases. There is a method for processing refractory gold-arsenic ores and concentrates, including melting of obtaining molten matte and slag (Masurian V.N., Borisov A.G., Strukova N.A. Distribution of gold and arsenic in products of melting refractory gold-arsenic concentrates, non-ferrous metals, 1986, No. 3, p.36-37). The disadvantage of this method is the low recovery of precious metals in the matte phase and the formation of environmentally hazardous exhaust gases (oxides of sulphur and arsenic). There is a method for processing refractory gold-arsenic ores and concentrates, including non-oxidizing melting obtaining molten matte and slag and rinse their lead (Patent RF №2110593, MPK SW 11/02. Publ. 10.05.1998,) (prototype). Be the oxidative fusion, conducted by a known method, significantly reduces the amount of exhaust gases melting and the content of environmentally hazardous products, however, cannot provide the dump slag content of noble metals due to incomplete allocation matte phase from the slag, which dictates his handling of metallophyte (e.g., lead) together with Stein. When this process is complicated and is performed in a periodic mode, which significantly reduces the efficiency of the process. The objective of the invention is to improve the recovery of precious metals in the matte, the lower content of precious metals in the slag to dump values and washing with metallophyte only matte in continuous mode. The problem is solved in that in the method for processing refractory gold-arsenic ores and concentrates, including non-oxidizing melting in the melting chamber to receive molten matte and slag and the melt processing of products metallophyte, according to the invention noncorrosive melting are continuously circulating in the slag melt with the issuance of smelting products in the settling chamber at the phase boundary of the slag-matte; before melting circulating slag melt is separated from the working gases; for circulation use maximally separated from the matte slag; - clicks the matte processing metallophyte carried out in continuous mode. Achievable technical result is to increase the recovery of precious metals in the matte and the lower content of precious metals in the slag. This is achieved due to more complete separation of the slag and matte in continuous non-oxidizing smelting refractory gold-arsenic ores and concentrates circulating in the slag melt held in the melting chamber with the issuance of smelting products in the settling chamber at the phase boundary of the slag-matte. The technical result is also that in well under stirring in continuous mode metallophyte washed only Stein. The technical result is also in better performance and continuous technological process. There is a method of melting materials circulating slag melt. The method is performed in a furnace containing the boot, gaslift and gazetteonline camera (Patent RF №2152436, IPC SW 13/00. Publ. 10.07.2000,) The disadvantage of the furnace is the lack of a settling chamber, which leads to the partial capture of the feed material and heavy melting component of the circulation flow of the slag melt. The melting of the materials is carried out in gazetteonline chamber, resulting in mixing of the gas transport stream sublimates. The known method per the processing refractory gold-arsenic ores and concentrates, including non-oxidizing melting obtaining molten matte and slag and rinse their lead (Patent RF №2110593, MPK SW 11/02. Publ. 10.05.1998,) (prototype). Melting in this way was carried out in an induction furnace including a melting chamber. The disadvantage is that the melting chamber of the furnace is running in periodic mode, which complicates the technological process and significantly reduces the efficiency of the process. The objective of the invention is the elimination of the mixing gas of the gas-lift and gazetteonline cameras and sublimates smelting, improving the efficiency of phase separation in the processing of matte phase melts of metals. The problem is solved in that in the furnace for the processing of refractory gold-arsenic ores and concentrates, including melting chamber, according to the invention the furnace is equipped with a recirculation circuit, consisting of a gas lift with lances and downward and upward channels of the slag melt, gazetteonline and settling chambers, with gazetteonline the camera is in communication with the melting chamber through the overflow siphon with channel for separating gas gas lift and gazetteonline camera from circulating slag melt, the melting chamber is immersed in a settling chamber at the phase boundary of the slag-matte, and settling chamber contains hath the d exhaust sublimates and boiling smelting products, - gazetteonline chamber contains a channel for blowing lance or burner; - settling chamber contains in the lower part of the well from blowing lance; - settling chamber contains a siphon for output metallobazy. In the inventive furnace circulation of the slag is carried out consistently through the recirculation circuit comprising a boot-descending and gaslift cameras, melting and gazetteonline cameras, devices for removing liquid products of melting and settling chamber. The furnace has two boot channel. In one of the boot channel connected to the downstream of the slag melt gas, introducing the solid fuel (coal)and the other channel is connected with the flow of the slag melt from gazetteonline chamber to the melting chamber, load charge (sulphide concentrate flux additives). Gazetteonline the camera is equipped with advanced channel to install the blast tuyere for afterburning of carbon monoxide and captured carbon or additional burner device for heating the circulating slag. Settling chamber at the bottom is well to collect matte connected to the siphon for its issuance. The well is filled with melt metallobazy to handle matte. For more efficient processing by using the blast tuyere create a weighted layer of metallia the s exhaust matte. The blast gases from the well send in a flue with a built-reflux The technical result is that in the furnace there is no mixing of the working gas, the exhaust of the gas and sublimates from the heat. Noncorrosive melting in the furnace is achieved by treatment of the mixture with superheated slag melt in the melting chamber in the absence of gas flow. This allows you to burn solid fuel with an excess of oxygen in gas-lift and gazetteonline the camera, and use in gazetteonline camera additional burner device for heating the circulating slag. Issuance of smelting products from the melting chamber to the phase boundary of the slag-matte settling chamber contributes to a more complete separation of the phases. This leads to the reduction of mutual entrainment of phases, thereby increasing the extraction of gold in matte. The furnace operates in continuous mode, which increases the efficiency of the process. The inventive design of the furnace is illustrated by drawings, where 1 shows a plan of the furnace, 2 shows a section of the furnace on gazetteonline camera figure 3 shows a section of the furnace for melting and settling chambers. Declare the structure contains: - gas lift 1 with lances 2, downward 3 and rising 4 channels of the slag melt, gazetteonline chamber 5, in which ver is her parts are connected by a channel 6 with a rising channel 4 of the slag melt in the gas lift and has a flue 7, overflow siphon 8, the channel issuing the excess slag 9 and channel 10 to enter the blowing lance or burner (blowing the lance or burner device not shown); - settling chamber 11, which is connected with the downstream channel 3 of the slag melt gas lift 1 trap 12 and has a flue 13; - the melting chamber 14, immersed the lower part of the settling chamber 11 at the interface of the slag and matte, connected by a siphon 8 gazetteonline chamber 5 through the channel 15 and having in the upper part of the boot channel 16. Downstream of the slag channel 3 is at the top of the feed channel 17. Matte phase is withdrawn from settling chamber 11 into the well 18 with suspended layer of melt metallobazy created by the blast tuyere 19, provided in the upper part of the duct 20 with a reflux condenser 21 for removal of the blast gases and return vozgonaetsa metallobazy in the process. Conclusion metallobazy is made through the siphon 22. Stein from the well 18 enters the separating chamber 23 having a boot channel 24 for supplying metallobazy, and the channel issuing matte from the furnace 25. In the lower part of the separating chamber 23 has a channel 26 for flow of metallobazy of the separating chamber 23 into the well 18. The method is performed in a furnace as follows. After heating the furnace to the melting chamber 14 through zagruzochnykh 16 pour metallobazy, then matte and slag. Volume metallobazy, matte and slag is calculated from design decisions. During filling of the slag melt furnace through tuyeres 2 serves blowing air in an upward channel 4 gas lift. When this begins adjustable recirculation of the slag melt between gaslift camera 1, channel 6 and sequentially gazetteonline camera 5, overflow siphon 8, a melting chamber 14, a settling chamber 11, through the siphon 12 downward channel 3 gas 1. Final heating of the furnace to operating parameters is performed without loading the charge by filing through the tuyere 2 preheated blast air and solid fuel that is loaded through the loading channel 17 in the downward channel 3 downstream of the slag. In the uplink channel 4 gas lift 1 is the combustion of solid fuels, such as coal, with its subsequent combustion and post-combustion of carbon monoxide in gazetteonline chamber 5 through the air blast supplied through the blast tuyere installed in the channel 10 (blowing the lance on explanatory drawings not shown). After warming up the whole of the brickwork of the furnace and the slag to the desired temperature start loading the main mass of the mixture (sulphide concentrate flux additives) through the loading channel 16 in the melting chamber 14. The volume of the metered charge is calculated OFL the exact amount of heat, bring slag in the melting chamber 14, is required to melt the charge, the higher decomposition of sulphides and distillation sublimates while maintaining gigaslave baths. The resulting melting of the charge of slag-matte melt layers due to the difference of densities and mutual necesitamos slag and matte on the slag and matte (sulfide) phase in the settling chamber 11. In this case, due to the directed flow of slag-matte melt down in the melting chamber 14 and the output of the melt from the melting chamber 14 in the settling chamber 11 at the phase boundary of the slag-matte provide a more complete separation of the slag from the matte. Excess slag formed from the mineral part of coal, slag-forming components sulfide concentrate and fluxing additives, derived from the process through the issuance of excess slag 9. Part of the slag is circulated in the oven, set by the performance of the gas lift. Circulating slag is cooled, transferring heat from the combustion of solid fuel in the melting of the charge. Accumulation of heat in the slag occurs during the combustion of solid fuels in an upward channel 4 gas lift 1 and the combustion him in gazetteonline chamber 5. Projekata phase of the gas lift 1 splits in gazetteonline chamber 5 on the gaseous and liquid phases. The gases are directed into the flue gas duct 7, and the liquid phase is via the siphon 8 and the channel 15 in the melting chamber 14. In the process of smelting of sulfide concentrates in the melting chamber 14 causes the decomposition of the higher sulfide with the formation of elemental sulfur and arsenic. Sublimates removed from the settling chamber 11 through the gas duct 13. The separation gas flows from the combustion of solid fuels in gas lift and gazetteonline chamber and process gas from the melting of sulfide materials in the melting chamber eliminates the formation of sulfur oxides in the flue and process gases, which greatly simplifies the system and makes the process environmentally friendly. Stein of the settling chamber 11 flows into the well 18 with metallophyte. By passing the matte in the well 18 through a fluidized bed of metallobazy generated by feeding an inert gas into the well 18 of the blower lance 19, there is an effective transition and noble metals in metallobazu. Conclusion the blast gases from the well 18 is made through the duct 20 through the reflux condenser 21. Matte phase of the well 18 enters the separating chamber 23 and then is output through the channel 25. In the separating chamber 23 through the loading channel 24 is introduced Metallobaza. Conclusion metallobazy is made through the siphon 22. Effective treatment of a matte metallophyte with the transition of precious metals from matte to metallobazu greatly simplifies recycling (or pererabotki is) Stein.
