Vat leaching process

Jul 13, 2016 As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak cyanide solutions, water washes, aeration of the sand and solution, and rapid filling and discharging. It is a cheap and effective process for clean ores when fine grinding is not necessary for good extraction

    Vat-Leaching Process Vat leaching can be described as leaching in a bathtub inside a building. In Vat leaching the ore usually after size reduction (either as a finely crushed or a coarsely ground and de-slimed) is manually loaded into the vats. Vats are tanks built by bricks, cement and sand may be rectangular or circular with a partial filter

    Other articles where Vat leaching is discussed: gold processing: Cyanidation: …ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced. The huge heaps described above are sprayed with a dilute solution of sodium cyanide

    Nov 02, 2016 Gold Vat Leaching. Gold Leaching done in round vats, constructed of wood, concrete, or iron and steel. If wood is used it is covered by a coating of paraffin paint, or by a mixture of asphaltum and coal-tar. Concrete and brick vats are not now advocated owing to their great cost and less convenient working, and wooden vats suffer more than iron
