Processing Sulfide Ores. Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching, our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur. With the aggressive nature of our leach allowing us to process most ores in an hour,...
Figure 4 CIL/ CIP Process Flow Schematic. Both CIP and CIL are continuous processes, where activated carbon is added to the ore/ water pulp. The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen.
First, crush the ore. Then, a chemical process is generally used to extract the metal. In gold's case, I believe it's a leeching process involving an arsenic compound. The solution is essentially sprayed on a big pile of crushed ore, with a rubber mat underneath to catch the runoff.
The next step in the process was to separate the gold amalgam from any 'unreacted' (leftover) mercury. We did this by squeezing the crude amalgam through a small piece of chamois leather. Shiny metallic beads of mercury oozed through the leather, and left the gold amalgam behind.
The process of extraction of metal from the concentrated ore depends upon the nature of the ore as well as the nature of impurities present in the ore. Before the concentrated ore is subjected to final metallurgical operations in order to get the metal in the free state, the preliminary chemical treatment may be .
Extraction and beneficiation methods of gold ores and minerals. If done on this type of ore cyanide treatment, will consume more cyanide, recovery rate is low. Therefore, for this kind of ore processing, there are often first by flotation method, then can use the oxidizing roasting heating pressure leaching method to further treatment,...

Going for gold: Alternative processing methods. But "when it is used with copperammonia as an oxidant for treating gravity concentrates, the gold leach rate can be higher than cyanide, though thiosulfate consumption in the process can also be high," Breuer explained.
Dunn (1982) and Dunn et al. (1991) have extracted gold by chlorination using pyrometallurgical processes at temperatures lower than the ones mentioned above, from refractory minerals and alloys, with a previous roasting process.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
