Properties of Copper Ores - University of Arizona

Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores.

Sep 15, 2019  Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.

Copper Mining and Extraction Sulfide Ores

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The world’s largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.

Copper mining. From ore to copper.

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper

Azurite - Wikipedia

Azurite is a soft, deep-blue copper mineral produced by weathering of copper ore deposits. During the early 19th century, it was also known as chessylite, after the type locality at Chessy-les-Mines near Lyon, France. The mineral, a basic carbonate with the chemical formula Cu 3 (CO 3) 2 (OH) 2, has been known since ancient times, and was mentioned in Pliny the Elder's Natural History under ...
