Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

  • Copper Mining and Extraction Sulfide Ores

    Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

  • Lime in Gold Ore Mining Process Flotation Cyanidation

    Aug 03 2019 · Lime has strong water absorption and reacts with water to become calcium hydroxide (Ca(OH)2) commonly known as slaked lime or slaked lime. It has little solubility in aqueous solution but it can further ionize calcium ions (Ca2 ) and hydroxide ions (OH-) in aqueous solution making the solution more alkaline.

  • ASARCO » Milling

    The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible. What doesn t float is called tailings because it goes out the "tail end" of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and re-used.

  • Stamp Mills for Processing Gold Silver Copper Ore

    A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. It uses heavy steel stamps to crush and break apart material releasing the valuable gold from worthless rock allowing for the extraction of gold for further refining.

  • Copper Ore Processing Methods

    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. The milling of copper ores as practiced in the larger
