Furthermore, it was found that PEO could function as a "collector" for quartz due to its affinity to air-water interface and quartz, and it could increase quartz entrainment when used at high dosages. Selective flocculation and depression of the quartz gangue during chalcopyrite flotation could only be achieved at low PEO dosages.

Fluorite mineral has rich colors. It is important fluoride minerals for the industry. Fluorite mineral common grows with calcite, dolomite, quartz, barite, pyrite, galena, blende and so on. Fluorite mineral has similar characteristics with calcite, barite and other common gangue minerals. It is difficult to separate them with flotation.

Calcination can be employed to separate calcite gangue; however, it should be applied after quartz flotation to avoid the formation of CaSiO 3 phase. To improve the flotation performance, the amount of < 45 μm particles should be reduced, and an alternative method is avoiding over-grinding.

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.

Gangue minerals, once separated by mineral dressing processes of (most of) the valuable ore minerals and dumped in mine tailings may be a significant environmental impact. In particular, oxidation of pyrite, a common gangue mineral, is one of the main sources of acid mine drainage. Re-use. Minerals that were once thought of as gangue, and were dumped, may later find a commercial use.

The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon.
