  • Carbon in pulp

    This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon-in-Pulp or Carbon-in-Leach process The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as...

  • Gold CIL process

    Cyanidation ---carbon adsorption process is the most widely used in gold cyanide extraction process The principle in brief is the carbon could adsorb liquid gold from cyanide solution In 1970s , with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold , make recycle the carbon and reduce the cost , and easy to process the gold ....

  • MODULAR AND SITE

    Since 1972, KCA has provided lab testing, engineering and/or field services for over 1,000 different gold recovery projects KCA has fabricated more than 50 portable or modular carbon adsorption, carbon desorption, carbon stripping and Merrill-Crowe plants...

  • Dynamic simulation of the carbon

    In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank This paper presents a dynamic model that describes, with minor changes, the carbon-in-leach, the carbon-in-pulp, and the gold leaching ,...

  • Carbon Adsorption In Recovery Of Gold

    The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton...

  • Gold extraction

    In other cases, particularly when the gold is present in the ore as fine particles or is not sufficiently liberated from the host rock, the concentrates are treated with cyanide salts, a process known as cyanidation leaching, followed by recovery from the leach solution Recovery from solution typically involves adsorption on activated carbon ....

  • DYNAMIC SIMULATION OF THE CARBON

    gold extraction plants In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery...
