    摘要: This invention provides an improved method of leaching precious and base metal values from ore comprising contacting a metal-bearing ore or ore concentrate with an oxidizing gas solution comprising a solution of an oxidizing gas dissolved in a perfluorinated liquid, said contact being made prior to or during extraction of the precious or base metal from the ore. In another aspect, this invention provides a method of destroying cyanide from a cyanide-containing solution comprising contacting said solution with a solution of an oxidizing gas dissolved in a perfluorinated liquid.
