The nature and chemistry of an ore deposit determine the processing method used in gold production. There are many processing techniques for gold ore. The most common is cyanidation in carbon-in-leach CIL, carbon-in-pulp CIP or carbon-in-column CIC circuits. Metso has a wide range of valves ideal for CIL, CIP, and CIC processing.

Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

2020-4-3Various mineral processing methods are used, often in conjunction with one another, to extract the ore from its rock encasement. Comminution, hydrometallurgy, and pyrometallurgy are used to extract the gold. Comminution is often one of the first steps in gold extraction. Extractors break apart the hard rock containing the ore.

In the first method, a machine called a hydraulic giant uses a high pressure stream of water to knock the gold ore off of banks containing the ore. The gold ore is then washed down into sluices or troughs that have grooves to catch the gold. Dredging and power shoveling involve the same techniques but work with different size buckets or.

Gold ores are considered refractory if gold extractions from a conventional cyanidation process are less than 80 even after fine grinding. 1 Arsenic-bearing refractory gold ore has stones extremely difficult to deal with. In the stones, gold is locked up in arsenic mineral matrix as the form of microscopic or submicroscopic lattice.

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
