Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops. In both mining techniques, the mined ore must be removed from the mine and transported to a plant for processing and refining. Trucks and trains are used for this purpose.

The pyrometallurgical production of copper from sulfide concentrates is a journey involving the gradual oxidation of copper concentrates in sequential steps. These steps are smelting, converting, and refining. The overall copper making process can be explained by using the copper–oxygen–sulfur predominance diagrams.
The final products of smelting and electrolytic refining are cathodes, cast often in the form of copper wirebars and cakes.* The casting are subsequently worked in various ways into wrought forms. Re-melted cathodes may also be cast into ingot bars suitable for the preparation of alloys.

Our main purpose, however, is to communicate the magnitude of the copper mining challenge to the broader public that is less familiar with upstream resource issues. To this end, the discussion is brief, non-technical, and focused on a single metal, diagram, and issue (vehicle electrification). All relevant methods and data are concisely ...
After mining, copper is produced by one of two process routes, pyrometallurgical (dry) or hydrometallurgical (wet). Smelting is a process of heating and melting ore to extract a metal like copper. Refining refers to any process that increases the grade or purity of the metal.
Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. Learn about how this process is carried out, along with examples and diagrams.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.
From its original home buried underground in a mine to its use in a finished product such as wire or pipe, copper passes through a number of stages. When it is recycled it can pass through some over and over again.
Copper mining typically involves several distinct stages, including exploration, extraction, concentration, and refining. Here's a brief overview of each of these processes: 1.
In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the …
Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap …
So the process of extracting cobalt from its ores is essentially the same as mining and refining copper, which we've already covered in this series. Briefly, crushed sulfide ore from vast open ...

Smelting and refining of copper cathodes are responsible for 20%–35% of the total emissions.6 ... models such as mining-specific energy efficiency (which one estimate showed could contribute to 7%–12% of the emissions reduction needed for the sector8), for example
The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample …
Direct and indirect greenhouse gas emissions from mining for green technologies need to be accurately and transparently accounted for, as highlighted by a case study of Chilean copper mining.
