    Extracting Gold HowStuffWorks

    How Gold Works. Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon in pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank,

    Making Gold Green New Non Toxic Method for Mining Gold

    May 14, 2013·The new process also can be used to extract gold from consumer electronic waste. Current methods for gold recovery involve the use of highly poisonous cyanides, often leading to contamination of the environment. Nearly all gold mining companies use this toxic gold leaching process to sequester the precious metal.

    Types of Extraction S cool, the revision website

    Methods of extraction. Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is.
