    After producing the nickel matte, further processing is done via the SherrittGordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%. Electrorefining; A second common form of further refining involves the ...

    Smelting is a process of extracting metals from their ores at high temperatures. Ores are mostly chemical compounds of metal with other elements, like oxygen sulfur. Smelting utilizes heat, and a reduction agent like coal, to extract the other elements from the metal according to Cornish Mining World Heritage. This results in a more refined ...

  • Innovations: Introduction to Copper: Mining Extraction

    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. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is ...

  • Copper in Antiquity Ancient History Encyclopedia

    04/10/2017· Availability Mining. Copper was easily found in its metallic state in many areas of the ancient world, albeit in relatively small quantities. The shiny red, orange or brown metal was first used in the Balkans, Middle East, and Near East from 8000 to 3000 BCE. Egypt and Europe later followed suit and began to make their own copper artefacts. Soft and malleable, it was an ideal material to ...
