  • Tank leaching - Wikipedia

    Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

    Carbon Adsorption In Recovery Of Gold From Cyanide Leach Solutions. It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject. Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until the 1970's, with the explosion of heap leaching of

    Metallurgy - Metallurgy - Leaching: Oxides are leached with a sulfuric acid or sodium carbonate solvent, while sulfates can be leached with water or sulfuric acid. Ammonium hydroxide is used for native ores, carbonates, and sulfides, and sodium hydroxide is used for oxides. Cyanide solutions are a solvent for the precious metals, while a sodium chloride solution dissolves some chlorides.

  • The Metallurgy of Cyanide Gold Leaching – An Introduction

    The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t). At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and cyanide solutions to form a high value electrolyte solution.
