smelting high grade silver and copper ore

Innovations in Copper Mineral Processing Technology

Reasons for Copper Ore Sorting cont. • Pre-concentrate feed into high-grade and low-grade stockpiles: – Optimize multiple process streams i.e. send ore to either mill, heap leach or smelter. – Allows smaller mills to be built or increase capacity of an existing mill. – Manage ore blending programs more effectively.

Copper Bottom Blowing Furnace Smelting

For copper metallurgy, bottom bowing furnace can treat copper oxide, copper sulfide ore, copper/nickel concentrates, copper scrap, brass and electronic waste material. The bottom blowing furnace has the advantages of less energy consumption, high utilization rate of oxygen and producing less off-gas amount with high SO 2 concentration.

Extraction Of Copper

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce), followed by tin, lead, and silver. To achieve the high temperatures required for smelting, furnaces with forced-air draft were developed; for iron, temperatures even higher were required. Smelting thus represented a major technological achievement.
