8 Types of Gold Ore- Properties and Ways to Process. Gold mainly appears in the form of natural gold and minerals in the ore such as pyrite, tellurium ore, sphalerite, and gold in gangue, etc. About 70% to 75% of the gold in the deposit is in the form of natural gold, while the other 20% occurs in the form of telluride. The remaining 5% to 10%

Refractory Gold. The last type of gold deposit is called refractory gold, and it is the most difficult type to extract. It can be defined as any ore that responds poorly to a conventional gravity-cyanidation process with examples including copper porphyry, complex sulfides, arsenopyrite and lead-zinc associations.

The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is 0.8-1.1 g/t. The leaching solution is spread at the top of the pile and the pregnant solution will have to percolate through the pile.

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold

effective adsorbents for gold cyanide, and resin processes (RIC, RIL, RIP), have been developed that are analogous to the carbon adsorption processes. In many cases, it can be demonstrated that processing of a gold ore with a resin will generate superior economic returns compared to carbon, yet the resin processes have been slow to gain

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Ore is stockpiled (1) 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 (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry.
