AN INTRODUCTION TO COPPER EXTRACTION

2.2 OVERVIEW OF COPPER EXTRACTION The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks. The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor. When the crushed ore falls onto the

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Copper Production: How Is Copper Made? - ThoughtCo

26-09-2019  Currently, about 80% of global copper production is extracted from sulfide sources. Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill. Sulfide Copper Ores .

Innovations: Introduction to Copper: Mining Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
