On average about 70 of the contained silver is recoverable through cyanide leaching. The other 30 is contained in refractorypounds or is silica encapsulated. Tin occurs as cassiterite in very fine grained, hypogene intergrowths with quartz and as powdery aggregates likely derived from oxidization of tin sulfide stannite and sulfosalts teallite and franckeite. Quartz is the
Usage: CNLITE is used in the same way as sodium cyanide in heap leaching, pool leaching and agitation leaching of gold ore. The reagent can be dissolved in solution with gold cyanide extraction. When used, the CNLITE gold leaching agent must be agitated with alkaline water at normal temperature and then dissolved in slurry for gold leaching. Activated carbon is the best
Therefore, cyanide agent dosage is one of the key factors determining the gold dissolution. In general, the pulp should contain a certain amount of unbonded cyanogen, then the gold cyanide leaching can keep normal. And the specific dosage of cyanide agent should be determined according to the property of gold ore. 4. Pulp density
Cyanide Leaching process is the main method of extracting gold from the ore and the concentrate in modern time. It includes some basic steps, such as cyanide leaching, leaching pulp washing filter, pulp cyanide solution or cyanide gold extraction and smelting of finished products. Generally, two processes of gold extraction are used in cyanide gold extraction
