pyrometallurgical process for copper minerals

pyrometallurgical process for copper minerals. A continuously growing demand for valuable nonferrous metals and therefore an increase in their prices at the metal exchanges makes it necessary and profitable to investigate alternative metal resources. Polymetallic deepsea nodules contain cobalt, copper, manganese, molybdenum and nickel, and are highly abundant on the

Pyrometallurgical Process - an overview - ScienceDirect

Because pyrometallurgical processes take place at high temperatures in which chemical reactions are fast, most steps in the overall process tend to proceed near equilibrium conditions. Therefore, the important principles involved in pyrometallurgical production of copper are related to the free energy/temperature relations and predominance-area diagrams; physical

COPPER Copper production - TU Delft

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

A TECHNO-ECONOMIC COMPARISON OF PYROMETALLURGICAL

About 90% of world copper production is produced pyrometallurgically from sulphide-based copper minerals, with the remainder from oxide-based copper minerals (Ayres . et al, 2002, Davenport . et al, 2002). Among the copper sulphide minerals, the main one is chalcopyrite (CuFeS. 2) comprising 50% of total copper production (CDAA, 2012). However, often

How Hydrometallurgy and the SX/EW Process Made Copper the ...

Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper
