  • Leaching (metallurgy) Wikipedia

    Chemistry. Leaching is done in long pressure vessels which are cylindrical (horizontal or vertical) or of horizontal tube form known as autoclaves. A good example of the autoclave leach process can also be found in the metallurgy of zinc. This reaction proceeds at temperatures above the boiling point of water, thus creating a vapor pressure inside...

  • Leaching Hazen Research

    The leaching process may employ one of a variety of chemicals such as dilute sulfuric acid, dilute aqueous cyanide, or other reagents. Methods for contacting ore and solution include agitating ground solids and solution (slurry) in open tanks, agitating slurry at a high temperature in a pressure vessel, or percolating solution through crushed ore that has been piled in a heap

  • Pressure leaching BioMineWiki Skellefteå

    Pressure leaching is the chemical dissolution of soluble minerals within a solid ore or concentrate carried out at elevated pressures and giving rise to a solution containing metals to be recovered. The process is carried out in closed autoclaves which permit higher temperatures (>220°C) and pressures (>20 atm) than are possible with open tanks.

    Elevated pressure conditions may be obtained, for example, by conducting a leaching process in a pressure vessel. Suitable pressure vessels include any type of closed environment or container in which a leaching process may be performed with application of elevated pressure levels. One of ordinary skill in the art would appreciate that

  • Pressure Oxidation Leaching Process

    Pressure Oxidation Leaching Process. At the end of the preoxidation period, the autoclave was cooled, and the autoclave solids were grab sampled. The remaining portion of the slurry was neutralized and then a 24hour carboninleach (CIL) cyanidation was conducted under standard conditions.
