Implementation of research results. On the development of an integrated technology for processing composite ash and slag waste from Angren and Novo-Angren TPPs the following have been introduced:
the developed combined technology for the enrichment and extraction of macrocomponents of CASW using the difference in the specific gravity of the components of ores, concentrates and mixtures in cyclones, based on centrifugal forces or a fluidized bed, which allows to extract macrocomponents – aluminum, iron and silicon – using ammonium fluoride and obtaining oxides Fe₂O₃, Al₂O₃, white carbon, REE concentrate and «underburning» was introduced in the chemical laboratory of Angren TPP JSC (Certificate of Angren TPP No 01/1446 AF from December 9, 2020). As a result, this made possible to extract macro components;
sorption extraction of microcomponents of composite ash and slag wastes from TPPs on «Purolite» cation exchangers (extraction of rare and rare-earth metals - gallium, cerium, lanthanum, scandium and vanadium; increasing the leaching efficiency) has been introduced in the rare metals production workshop of the copper smelting plant at Almalyk MMP JSC (Certificate of Almalyk MMP JSC No 63-500 from December 29, 2020). As a result, this made possible to extract rare and rare earth elements – gallium, cerium, lanthanum, scandium and vanadium; improve leaching efficiency;
the sorption method for concentrating rare earth metals on various cation exchangers «Purolite» and the optimal conditions for their extraction have been introduced in the rare metals production workshop of the copper smelting plant at Almalyk MMP JSC (Certificate of Almalyk MMP JSC No 63-500 from December 29, 2020). As a result, the sorption of gallium on the sorbent «Purolite S-930» made possible 92% the extraction.
