Lead and Zinc Energy

2013. 11. 8.  Treatment of lead and zinc ores begins with milling. Milling is a multi-stage crushing and grinding operation. It involves coarse crushing followed by wet grinding. Crushing is usually a dry operation that utilizes water sprays to control dust. Primary crushing is often performed at the mine site, followed by additional crushing at the mill. The crushed ore is mixed with water

2020. 11. 2.  Standard crushers, screens, and rod and ball mills classify and reduce the ore to powders in the 65 to 325 mesh range. The finely divided particles are separated from the gangue and are concentrated in a liquid medium by gravity and/or selective flotation, then cleaned, thickened, and filtered. The concentrate is dried prior to shipment to the smelter.
