Role of extraction processes in improvement of methods of complex utilization of ores
Abstract
One of the most important tasks of beneficiators and metallurgists is to find better methods of complex utilization of polymetallic ores: lead-copper-zinc and copper-zinc ores containing, in addition to base metals Si, Pb, Zn, a number of other satellite metals - Au, Ag, V, Cd, Se, Te, Sn, Tl, Ge, In, Ni, Co, As, Sb, Hg and others. The value of base metals, including noble metals, contained in the ores is often no more than 50-70% of the value of all metals in the ores.Conventional methods of enrichment of most polymetallic ores do not provide rich and pure selective concentrates with sufficiently high recovery of the corresponding metals of the same name. The recovery of lead in lead concentrate is 75-88%, zinc in zinc concentrate 78-85%, copper in copper concentrate 68-78%.
