how can a mining engineer extract copper out of the ground

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).

Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.在copperalliance上查看更多信息

Mining Methods 101: How the Metals We Need Are Extracted

Jul 06, 2016· Before that can happen, however, the ores must be excavated from the ground. Typically, this is done through two basic techniques: sub-surface (underground) and surface mining. Surface mining is both the less expensive of the two and the go-to method when the desired minerals are located near the surface of the Earth.

New approaches for extracting and recovering metals from

May 15, 2017· Extraction of copper (∼55%) was similar when Bor tailings were bioleached at 30° or 45 °C at pH 1.7 and in constant aerobic conditions (Fig. 3a and b). As with CLC tailings, concentrations of soluble iron declined after an initial rapid increase (at 45 °C), and there was greater evidence of co-precipitation of copper than in the case of

Copper Mining and Processing: Everything you Need to Know

The Basics of Copper Mining and ProcessingWhat Is Copper Used for?The Copper Mining ProcessMined 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. The oxides are smelted to produce matte, which then undergoes several refining processes.

Current Energy Requirements in the Copper Producing

Dec 20, 2013· An analysis of energy usage in the production of refined cathode copper was made from mining ore to cathode copper. In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the “recovery efficiency” of the metallurgical processes used to extract the copper. The mining and mineral concentrating energies are directly proportional to the

From Ore to Finished Product Copper

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
