Copper - Sulphuric Acid

Mitsubishi Process. The process is a continuous, multi-step process which produces blister copper from concentrates in three interconnecting furnaces. Concentrate and oxygen-enriched air (30-35% O2) enter the smelting furnace through vertical lances and are smelted to produce a matte of 65% to 69% Cu and low-copper slag. Fuel must be burned to satisfy the heat balance in the smelter chamber. The high

Blister Copper - an overview ScienceDirect Topics

The three steps of copper extraction (roasting, smelting, and converting) can also be carried out continuously by using the Mitsubishi process or the Noranda process. The Mitsubishi process consists of three furnaces in series (a smelter, an electrical settling furnace, and a converter). The Noranda consists of a single furnace where the concentrate is converted into matte and blister copper as the material

Copper Ore Processing Methods

11/04/2017  The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.
