Stages of hydrometallurgical processes | PPT
The document summarizes the key stages of hydrometallurgical processes. It discusses three main stages: leaching, solution concentration and purification, and metal recovery. Leaching involves dissolving metals from ores using techniques like heap, vat, or agitation leaching. Solution concentration and purification removes impurities.

Concentration Of Copper Ores In North America
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few cases, however, leaching takes the place of concentrating, smelting, and refining, and in others ores are smelted without being concentrated. Copper ores have been milled since the early days of mining in the United States.
