  • Leaching Mining Fundamentals

    Leaching is a chemical process in mining for extracting valuable minerals from the ore. Leaching also takes place in nature where the rocks are dissolved by water. Post leaching, the rocks areleft with smaller proportion of minerals that they originally contained.

    The use of thiourea as an alternative lixiviant to gold cyanidation for processing goldbearing ores or concentrates was first developed by Soviet metallurgists in the 1940s. However, the interest for thiourea leaching of gold mainly came during the 1980s and 1990s to establish a parallel process.

  • Leaching in Metallurgy and Metal Recovery

    1) Vat Leaching: Also known as "agitated tank" leaching, the lixiviant comes into contact with the metal material in large vats or tanks, which can be stirred, enhancing the reaction kinetics. The metal containing solid, such as concentrate, ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching.

  • Hydrometallurgy

    For a high degree of metal extraction from an ore, the dissolution of the value metals must be as complete as possible, which is the primary consideration in the implementation of any leaching operation. Any valuable metal that remains unreacted in the ore, after leaching, constitutes a loss of the metal (Woollacott Eric, 1994:329).
