Just crush the ore in a mill and process it gravimetrically, ie spiral concentrators, shaker tables and other automatic panning devices. 2. Gold is the primry ore but so fine grained that it can't be seen with the naked eye. Crush the ore finely and leach it with cyanide. 3. Gold is associated with sulphides in a complex ore.

ORE PROCESSING The onsite mill processes up to 3,500 tons of ore daily. Gold is recovered using several unit operations. Once the ore is delivered to the mill, the grinding circuit reduces the ore to a very fine particle size (about half of the size of a grain of table salt). This is the first step in separating the gold from the rest of the rock.

The process began with roasting (burning) the ore for six weeks in the open air. This reduced the sulfur content but spewed sulfur dioxide into the air. Then the ores were smelted in a furnace. The gold, silver and copper settled to the bottom of the liquid. Workers skimmed the worthless slag from the surface of the matte, the amalgam of minerals.

The three most commonly used processes for gold ore separation are: gravity separation, flotation and cyanidation. Among them, gravity separation is a commonly used process in placer gold mines, flotation is mostly used in rock gold mines, and cyanidation is suitable for refractory gold ores such as oxide ore and flotation concentrate.

In the process flow, the gold ore is firstly subjected to flotation operation, and a small amount of concentrate obtained by flotation is then subjected to cyanidation leaching. Compared with all-slime cyanidation, this process does not require fine grinding and leaching of all minerals, which is more time-saving, labor-saving and money-saving. 2.

Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
