    Jan 01 2016 The lower adsorption of Cu CN 3 2 − and Cu CN 4 3 − onto activated carbon accounts for the use of high cyanide concentrations to improve the selectivity of gold over copper when this adsorbent is used for gold recovery. In contrast the use of low cyanide concentrations is used to promote selectivity and higher adsorption of Cu CN 2 − on to activated carbon as a copper removal .

    Gold Recovery And How To Choose The Right Process

    Free-milling gold can be further classified into low grade and high grade which helps determine the most economical and optimal gold recovery method. Low Grade. Low grade free-milling gold deposits contain less than 1 gt of gold. This low grade ore is crushed and heap leached to recover the gold. While heap leach recoveries are lower than in conventional gravity-cyanidation the savings in capital expenditure

    Oct 20 2014 Liberation Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen the ore should either be sufficiently porous for cyanide to reach the gold or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed – i.e. the gold is liberated.

    Crushed ore agglomeration and its control for heap leach

    Feb 01 2013 Weathered ores contain enough fines that cause severe issues for percolation. For example oxidized massive sulfide gold ores are so soft and permeable that even crushing below 75 mm does not increase gold recovery e.g. Filon Sur ore body Tharsis Spain and Hassai Mine Sudan. There can be serious issues in multiple lift and higher height .

    Aug 20 2017 Increased gold recovery from an ore can be obtained because additional gold may be liberated by finer crushing without encountering particle segregation during preparation of ore heaps. Particle segregation in unagglomerated materials can cause localized accumulation of fines that inhibit flow of leaching solutions.
