activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon-in-pulp (CIP) and the carbon-in-leach (CIL) processes, have been widely used since the 1970s. Due to the economic

High concentrations of 238U,232 Th and 226Ra in products were found to be at a level of 104 Bq/kg. Around the South China Mineral Processing Industry, radioactivity in soil and groundwater was ...
Get Price. Gold Carbon-in-pulp (CIP) production is the sequential leach, then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud ...
· However the preparation of a gold production report is often complicated by the large inventory of gold in the carbon in pulp (CIP) or carbon in leach (CIL) tanks used to adsorb leached gold from the solution. Indeed a 600 m 3 CIP/CIL loaded with 15 g/L of activated coal charged with 8000 g of gold/ton of coal may retain up to 72 000 g (2200 ...

Ore Leaching Process Gold recovery using the heap-leach method is based on the process of applying a leachate that usually contains about 100 to 600 parts per million (ppm) (0.01 to 0.06 percent) NaCN in a water-based solution to a large pile of crushed or run-of-mine rock and, occasionally, mill tailings (Hoye, 1987; van get price.
Effect of pH on Au Recovery in the Presence of 0.25% Stibnite (After Hedley & Tabachnick 1968) Extrapolating the above trend back to the ordinate axis we note that recovery is once again achieved at pH 8.9 but with the reservation that gold recovery will reduce somewhat, and cyanide consumption increase, as the free CN- ion is replaced by dissolved HCN at the lower pH.
carbon-in- pulp (CIP) or carbon-in-leach (CIL) processes for the recovery of gold directly from leach pulps. Instead, SGS will evaluate the following gold recovery options for your project: • Resin-in-pulp technology involving direct recovery of gold thiosulphate from the leach pulp by adsorption on strong-base anion exchange resin.
