How lead is made - material, used, processing, product, industry .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.lead oxide mining process,Oxide Lead Treatment & Extraction by Flotation & Gravity Methods .Oxidized ores give trouble from the time the ore enters the mill ore bin until the tailings reach the tailings.
Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture.
