  • What Is the Percolation Leaching Process? - Xinhai

    The percolation leaching process is a common mineral processing method used in the treatment of abandoned pillar, surrounding rock, tailings and low-grade minerals. The percolation leaching process is a kind of leaching method in which the leaching agent penetrates the fixed ore bed in a top-down or horizontal manner by means of gravity or pressure. It is the key to ensuring the economic

  • Leaching - Mining Fundamentals

    2014-03-05  The leaching process in mining is carried out either as heap leaching or insitu leaching. Precious metals such as gold are extracted from their ores by a cyanide or ozone leaching process. Radioactive metals, such as uranium are extracted by the process of acid leaching. Choosing the appropriate leaching method for metal extraction is done based on economic and environmental viability.
