If everything apart from nickel and copper is designated as gangue, then IGF is point 0.497 and 99.05% gangue in feed. The same is seen for a plot of gangue floatability against per cent gangue inflow feed.

Flotation of Iron Ore: A Brief Review

Jul 30, 2020  In some iron ores, removal of non-quartz gangue minerals is also essential, which has been the subject of several studies [16,19–23]. These non-quartz gangue minerals include alumina-containing minerals, phosphorus-containing minerals, iron-bearing carbonates, and iron-bearing silicates. The presence of

May 01, 2017  It is possibility because of increase of iron and apatite minerals into the concentrate in the higher pH which results in the decrease of the P 2 O 5 relative floatability. This behavior is due to the fact that pulp pH value plays a significant role in flotation through its influence both on mineral floatability and reagent function.

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.

Gangue - Wikipedia

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.
