vat bottom Explanation: https://en.wikipedia.org/wiki/Tank_leaching In vat leaching the solids are loaded into the vat, once full the vat is flooded with a leaching solution. The solution drains from the tank, and is either recycled back into the vat or is pumped to the next step of the recovery process. . Vat leach units are rectangular containers (drums, barrels, tanks or vats), usually very big and made of wood or concrete, lined with material resistant to the leaching media. The treated ore is usually coarse. https://pt.wikipedia.org/wiki/Lixiviação http://www.cetem.gov.br/publicacao/extracao_de_ouro/capitulo... |
