In the Republic of Uzbekistan, lead metal is mainly produced at the lead plant owned by Almalyk MMC JSC. Production is carried out in the traditional way through the processes of enrichment roasting, selective smelting of lead and electrolysis. The lead cake formed during the selective smelting process is roasted in a welschizing furnace with the participation of coke. The secondary welschizing oxide (SVO) formed as a result of the purification of raw welschizing oxide (RVO) from halogens and reducing agents by roasting was first washed and roasted at high temperatures in the presence of limestone and coke powder. As a result of the experiments, the chemical composition of the products obtained was studied.
