2019-12-26Many definitions of the word slime have been attempted to Leaching Fine Gold but the one that best expresses its meaning from a practical point of view is that given by Park that it is that part of the pulverized ore that is not percolable on a commercial scale without the use of pressure. The consequences of this definition are that slime cannot be treated commercially by the same ...
2017-12-7Production Output The effect of pH on gold extraction. Condition 20 solid, 0.6 MPa, 300 min-1, 80C, 1 NaCN, 1 h Parga et al., 2007. The recovery of gold in the leaching process is the result of a chemical reaction which is pH dependant. Optimum levels of gold extraction can only occur when the pH is at the correct level. The extraction ...

2016-7-21The cyanide concentration played an important role in the efficiency of the gold transfer from the carbon to resin. An increase in cyanide concentration in the lixiviant from 200 to 1000 mgL at the lowest resin-to-carbon ratio tested 0.03 mm increased the gold recovery from 15 to 35, respectively, as shown in FIG. 4.
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold
