  • Leaching (metallurgy) Wikipedia

    OverviewChemistrySee also

    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 o

    Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering– solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considere

  • Gold Metallurgy and Leaching Process

    Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes
