1. Less sulfide containing gold ore. Gold is the only recycling object, other minerals or no industrial value or only by-product recovery. Sulfide is mainly pyrite, with little content, sometimes with a small amount of copper, zinc, lead, molybdenum and other minerals. The natural gold particle size in this ore is relatively coarse, the product is single, and the simple flotation process can be used to better recovery.


2. Sulfide containing gold ore. This kind of ore pyrite or arsenopyrite content, also has the recovery value. The gold grade is low, the change is not big, the natural gold grain is relatively small, and is wrapped in the pyrite. It is easy to select gold and sulfide from this type of ore, but the separation of gold and sulfide requires more complex process.

3. Multi metal gold bearing ore. This kind of ore in addition to gold sometimes also contain metallic minerals of copper, lead and copper, lead, zinc, silver, tungsten, antimony etc., they also have separate mining value. Its main characteristics is sulfide minerals account for a considerable proportion (10% ~ 20%); natural gold in addition to closely and pyrite, mostly with copper, lead and other minerals closely associated; natural gold particles are different, of this kind of ore need complicated metallurgical process flow.

4. Gold bearing gold ores. In addition to natural gold, there are a considerable amount of gold in the form of gold in the form of low temperature hydrothermal deposit.
