Improved Method for the Recovery of Lead and other metals polymetallic Mineral Resources containing lead, and Concentrate polymetallic Compound made from the same

摘要

A method for the Recovery of metals from a mineral resource containing polymetallic Lead, zinc, and other metalsThe Method comprises the separation by Flotation of polymetallic mineral resource while only suppresses the Flotation of zinc and other metals in the measure that does not substantially affect the Flotation of lead to form a compound that contains Lead Concentrate and Tailings containing Zinc Concentrate; subjecting the composite to a recovery process in which a solution of lead acuOsa Fluoroborato fluorobu00f3rico FERRIC acid leached lead from Lead Concentrate, and lead is recovered from the solution by electrowinning; and further processing of the Concentrate leaching to recover at least an additional metal.
