“…When autogenous technologies are used to smelt sulphide raw materials, slags are formed that require separate processing for additional recovery of non-ferrous metals [19]. The main principles of the continuous smelting process for copper sulphide concentrates with reduction finishing of slags in the tail zone of the PV furnace (Vanyukov melting furnace) have been developed to obtain slags with a minimum copper content of 0.5-0.7% [20]. Slag reduction is performed by adding a carbon-containing reductant (coal, coke, shungite, etc.)…”

The article presents the most innovative technologies developed by Satbayev University, "Institute of Metallurgy and Ore Beneficiation" JSC (Republic of Kazakhstan, Almaty) in recent years. The implementation of these works on an industrial scale will lead to significant economic and environmental effects. The following technologies are described: synthesis of a new foaming agent for intensification of flotation enrichment of gold-bearing ores; multicomponent microflotation, which allows to increase the extraction of valuable metals at existing deposits and to develop new, relatively poor and previously economically unpromising deposits; flotation enrichment of persistent gold-containing ore; contractile pyrometallurgical selection, which allows direct melting of persistent gold-containing raw materials with the transfer to the gas phase of arsenic, sulfur and other volatile components, followed by their neutralization and concentration of gold, silver and other non-ferrous metals in matte melt; continuous conversion of copper matte in the Vanyukov furnace; processing of liquid metallurgical slags in a furnace with an electrically heated coke filter; vacuum distillation refining of rough selenium; extraction of rare earth metals from extraction phosphoric acid obtained during the processing of phosphorites; processing of high-grade low-quality bauxite.

“…In the experimental part, BCP charge materials were used. The melting of the charge with the introduction of different amounts of activated carbon (0, 2, 4, 6, 8 g) was performed according to the well-known method [18]. The charge weight was 100 g, the melting temperature was 1300 C, the exposure at the melting temperature was 30 minutes, each experiment was repeated 4-5 times.…”

Due to the change in the composition of the processed raw materials at the Balkhash Copper Plant (BCP), it is required to adjust the technology used to melt copper sulfide concentrates in the Vanyukov furnace (VF). It is promising to use additional carbon-containing fuel that burns in the bubbling zone increasing the melting temperature and partially reducing slag oxides to ensure the required autogenousity and melting temperature. However, part of the solid fuel does not burn in the bubbling zone with an oxygencontaining blast and does not participate in reduction reactions with slag oxides that result in its accumulation on the surface of the slag melt.The results of the industrial tests performed earlier in the BCP to feed coal dust through tuyeres to the VF with the purpose to maintain the required temperature of the slag melt and satisfactory separation of slag and matte were considered. The reasons for the unstable operation of the tested system to feed coal dust to the VF through tuyeres were determined, and directions for its improvement were outlined. Laboratory experiments were performed to simulate the behavior of coal dust in the quiet zone of the VF. The regularities of the distribution of coal dust were determined, and it was shown that coal dust was concentrated on the slag melt surface. Thus, coal dust that did not react with blast oxygen or oxides of the slag melt in the bubbling zone was carried to the surface of the slag melt, promoted the formation of a viscous crust, and then practically did not interact with the slag melt and becomes practically useless.
