HYDROMETALLURGIC PROCESS FOR TREATING LEAD CONTAINING SULFIDIC COMPOUNDS

摘要

The specification describes a hydrometallurgical process for treating a mixture of metal sulphides containing lead sulphide, wherein the sulphide mixture is treated with an aqueous lixiviating solution containing at least one chloride selected from the chlorides of copper, bismuth, antimony, arsenic and silver, the quantity of the said chlorides used being not more than 120% of that which is stoichiometrically required for the complete dissolution of the lead contained in the sulphides.
