Mineral processing - WikipediaHow lead is made - material, used, processing, product

Dewatering is an important process in mineral processing The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangueOnly half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteri Besides the ore itself, only a few raw materials are necessary for the refining of lead The ore concentrating process requires pine oil, alum, lime, and xanthate.
