Copper mineralization occurs in many forms and in a variety of geological settings.As such, there are various factors to consider when determining the value of different types of copper deposits.

Copper Ore Processing Methods

2 天前  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. The milling of copper ores as practiced in the larger

Metal Production from Concentrates Aurubis

Aurubis imports most of the copper concentrates directly from copper mines in different countries. Copper ore is primarily mined in Central and South America, the US and Canada, as well as Africa, Asia, Australia and to a lesser degree in Europe. Copper ores contain about 0.5-4 % copper and are already processed into a concentrate in the mine.

COPPER Copper production Repository

2008-12-16  About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
