Gangue Mineral - an overview | ScienceDirect Topics

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.

Aug 01, 2017 · Micro-flotation on single and mixed minerals and bench scale flotation tests on a low-grade complex pyrochlore-bearing ore were conducted with the objective to assess the flotation behavior of ilmenite as a gangue mineral in the flotation of pyrochlore with benzohydroxamic acid as a collector and sodium hexametaphosphate as a dispersant/depressant.

Mineral processing - Concentration | Britannica

Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...

Gangue - Wikipedia

Minerals that were once thought of as gangue, and were dumped, may later find a commercial use. When this happens, the old dumps are often reworked to extract the wanted mineral. For example, in copper mines in the 19th century the mineral arsenopyrite was dumped until arsenic became popular as an insecticide later in the century.

Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

During flotation, the ore is treated with reagents (chemicals) to encourage the valuable sulfide minerals to float and suppress the non-valuable minerals. Unfortunately, not all of the economic elements are contained within sulfide minerals (e.g. they may exist in oxides) and non-valuable gangue minerals can also float (e.g. talc and clays ...
