Minor silver in the ore reported in the carbon in amounts of up to oz/ton. Gold adsorption rate data and an equilibrium adsorption curve for minus plus mesh carbon at ambient temperatures were developed and used in the successful application of a cascade design ://   A countercurrent, carbon-in-pulp, pilot plant test was made for the adsorption and recovery of gold on minus 6- plus mesh coconut carbon from cyanide leach slurries of the jig tailing. The ore was in two lots containing and oz/ton Au and was leached in cyanide solutions containing and pet NaCN, respectively, at pH   Carbon adsorption of gold, silver, and mercury from leach pulps or solutions is usually 90 to pct; however, the addition of lb/st CaS to the slurry reduced mercury and silver adsorption to between 0 and 8 pct and 0 and 6 pct, respectively, with all ores except the high-silver-copper 5-M :// Carbon-in-pulp silver adsorption from cyanide leach slurries of a silver ore / ([Washington, D.C.]: Dept. of the Interior, Bureau of Mines, []), by Stuart J.

  The carbon is then removed by screening, across a carbon screen, allowing the liquid and finely ground ore ( mesh) to pass through easily, and retaining the carbon on the screen. The carbon is then generally subjected to a heated solution ( deg to deg F) of (1%) sodium hydroxide and (%) cyanide and the gold is re-dissolved and   Improving the process performance of gold cyanide leaching reactors 3 literature (Equation [1]) shows that k L a is a function of mixing power intensity (P/V) and superficial gas velocity v s.

Carbon fines that are produced by abrasion pass through the inter-stage screens and move co-current with the pulp down the adsorption cascade. The barren pulp is screened at – mm to recover undersize carbon. Tailings are pumped to a 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 ?script=sci_arttext&pid=S

The introduction of activated carbon to recover gold from cyanide leach solutions in the last quarter of the 20th century had a breakthrough impact on the economics of gold ore processing, as the world gold industry entered a period of unparalleled expansion following the deregulation of Carbon-in-pulp silver adsorption from cyanide leach slurries of a silver ore / In a typical gold processing plant, gold is extracted from ore using an aerated alkaline cyanide solution and recovered from the solution by activated carbon (AC) through carbon in pulp (CIP) or   adsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it is shown that a variety of metal-cyanide species can be used to leach gold from certain refractory ://
