Pouring blister copper into anodes at the Uralelectromed plant for subsequent electrolysis
Raw metals - some non-ferrous metals obtained (by smelting ores) with a significant content of impurities (e.g. blister copper , lead ( verkbley ), zinc , etc.). With further purification ( refining ), impurities are removed. For example, to cleanse impurities, Wercbley is first heated to a temperature of 900-1000 ° C, and after the start of the subsequent cooling process, it is quickly cleaned of impurities, since they are poorly soluble in lead at slightly lower temperatures .
