Copper Mining and Extraction Sulfide Ores

Copper minerals and ore are found throughout the Earth’s crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock.

Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Innovations: Introduction to Copper: Mining

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.

Copper Mining and Extraction Copper Mining

Copper is extracted in large amounts from the Earth’s crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate ores.

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

These secondary copper minerals may form rich ore in the upper parts of many deposits, and owing to their characteristic green or blue colour, even small amounts are easily seen in the rocks in which they occur. Copper bearing minerals are commonly found in association with minerals which may contain gold, lead, zinc and silver.

Mining in Cornwall and Devon - Wikipedia

Mining in Cornwall and Devon, in the southwest of England, began in the early Bronze Age, around 2150 BC, and ended with the closure of South Crofty tin mine in Cornwall in 1998. Tin, and later copper, were the most commonly extracted metals.Some tin mining continued long after the mining of other metals had become unprofitable. Historically, tin and copper as well as a few other metals (e.g ...

The Basics of Copper Mining and Processing Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.

Impacts of copper mining on people and nature

The mining industry uses sulphuric acid in the extraction and treatment of copper. The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people’s skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage nearby buildings.

Ethical issues - Copper

The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron. Other precious metals were also used mainly for gilding or coinage. To begin with, many metals were obtained through open-pit mining, and ore was primarily extracted from shallow depths, rather than though the digging of deep mine shafts.

01-09-2020  Implementing ISR bioleaching with the in situ mining scheme requires extraction of a fraction of the ore to be able to form an ore bed with porosity adequate to operate in a trickle bed. This approach implies in practice a trade off with respect to the standard ISR practiced in uranium and copper oxides, in which none of the ore is extracted.
