Copper Mining and Processing: Everything you Need to Know

Mining Methods. However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task. Open pit mining is a technique used to extract copper ore near the earth's surface. Open pit mining is the most widely used technique of mining copper today.

The Extraction of Copper

Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Innovations: Introduction to Copper: Mining Extraction

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. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper

Copper Mining Using Acidothiobacillus

Copper is rarely found in its native form; most often it exists as ores made up of various copper sulfides and oxides that have little practical value of their own (Australian Atlas of Minerals, Resources, and Processing Centres). As such, methods for mining copper involve long and complex chemical processes to produce metal from the ores.

How Mining Works

The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies. Here's how it works. Ore, rock containing economically recoverable copper, is extracted from the bottom of the ore body. A void, or cave, is then created.
