  • Gold CIL CIP Gold Leaching Process Explained CCD

    The carbon-in-pulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid. The ground ore overflowing the sizing device generally runs at 25 to 35 percent solids. First it is passed through a ...

    grade and nature of the ore and the number of leach reactors in series may range from 6 to 12. After leaching, the pulp is passed over a feed screen to ensure removal of tramp material such as -chips, plastics and grit larger than about 0.6 mm. This is done to minimize screen blocking in the adsorption section. After feed pre-screening the pulp flows through a cascade of well-mixed ...

    Leached pulp and carbon are transferred in a counter current flow arrangement between a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with low grade or tailings solution. At this tank the fresh carbon has a high activity and can remove trace amounts of gold (to levels below 0.01 mg/L Au in solution). As it moves up the train, the carbon loads to higher and higher concentrations of gold, as it comes in co

  • Carbon Adsorption In Recovery Of Gold - Mine

    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. If the ore is a high grade, it may be feasible to tank leach it. By high grade, it would probably be ...

    Heap leaching provides relatively low-grade, clear solutions from which the gold has to be recovered. In practice, carbon-in-solution (CIS) is generally used for the upgrading of the gold. With developments around gold-selective anion exchange resins over the past few years and the recent commercialization of a number of these resins, resin-in-solution (RIS) has become an alternative for the ...

  • Cyanide Leaching Mining SGS

    Heap leaching facilitates the profitable extraction of gold from very low grade ore. Prior to heap leaching, either run of mine (ROM) or crushed ore is heaped into structures 10 to 20m high that are stacked on an impermeable layer. A dilute cyanide solution is sprayed on the heap, percolates through the pile and dissolves the available gold. The solution is then directed into a pond. The ...
