Ore processing – Waihi Gold

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along

Primary Lead Processing. Primary Lead production begins with sintering. Concentrated Lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. The mixture is blasted with hot air to burn off the Sulphur and sent to the smelter. Lead Melting Technology

Rockster's DUPLEX System for processing lead ore Mineral

T he P.B. Mining Company Ltd. was formed in 2014 and is specialized in the exploration of lead glance also named galena. Galena is the natural mineral form of lead sulfide. It is the most important ore of lead and usually contains about 1 – 2 % silver, a byproduct that far outweighs the main lead ore in revenue. Because of its low melting point, it is easy to liberate by smelting.
