  • Mining and mineral processing The lithosphere Siyavula

    Extraction techniques: Gold: Underground mining (shaft mining) and surface mining. Gold cyanidation is used. The ore is chemically treated to extract the gold. Iron: Surface mining (open pit mining). Smelting and chemical reduction. Phosphate: Surface mining (open pit mining). Treatment with acid. Coal: Surface mining (open pit mining). Underground mining is now starting to become more common.

  • Extracting Gold HowStuffWorks

    This causes gold to collect on the negative terminals. ­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold. Molds are used to transform the liquid gold

  • Gold extraction Wikipedia

    Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold

  • Extracting Gold HowStuffWorks

    Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In
