Flotation of Gold and Gold-Bearing Ores

Differential flotation of the iron sulfides (Poling and Beattie, 1984) pyrite, pyrrhotite, and arsenopyrite is a unique process in the gold industry. There is scope on some gold mines for differential flotation of pyrite from arsenopyrite, or vice versa (Draskic et al., 1984, Beattie et al., 1992, Kogan et al., 1986). This is due to the fact ...

In the process of extraction of iron from iron pyrite ore, …

In case of iron pyrite the ore particles are magnetic in nature hence it can be concentrated using magnetic separation. Also as the formula FeS 2 suggests - does have sulphur atoms. Froth floatation is mainly used for sulphide ores. So, we can definitely use froth flotation process for concentration.

4 Extraction Processes for Gold-Pyrite Ore

In process IV, we first treat the ore by flotation, then roast the flotation concentrate, and do cyanidation afterwards. After all these, we do a secondary cyanidation to lean liquid and tailings. This process is suitable for processing ore that contains both non-sulfide gold and fine-grained gold encased in sulfide. 3.

The Importance of pH in Flotation

To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit.

Physiochemical separation of iron ore

The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5 ) (OH) 4) and gibbsite (Al (OH) 3 ). Some progress has been made in using flotation to separate kaolinite from hematite. High levels of phosphorus in iron ore attract a penalty because this makes steel brittle.
