Leaching In Mineral Processing

  • Leaching (metallurgy) Wikipedia

    Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while impurity remain insoluble.These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings. Compared to pyrometallurgy leaching is easier to perform, requires less energy and is potentially much less harmful as no gaseous pollutionoccurs. Drawbacks of leaching include its lower efficiency and the oLeaching 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.
