The grade of weathered tungsten ore becomes lower, and it is embedded in a large amount of ore mud, which is prone to mudification, resulting in poor mineral surface activity, which seriously affects the recovery of tungsten ore.
Fluorite can be roughly divided into seven types: single-type fluorite, quartz-type fluorite, sulfide-type fluorite, calcite-type fluorite, barite-type fluorite, siliceous rock-type fluorite, and carbonate-type fluorite. Depending on the type of fluorite, its beneficiation methods are also different.
According to the properties of different phosphate ores, the beneficiation processes used are also different. At present, commonly used phosphate ore beneficiation processes at home and abroad include forward flotation, reverse flotation, scrubbing and desliming processes, gravity separation, roasting and digestion, etc.
The presence of silicon and sulfur in bauxite has a significant negative impact on production quality, so the development of effective desilication technology is crucial. This article will explore several commonly used physical desilication methods.
Due to the complex composition of high-arsenic gold ore, the gold is generally embedded in pyrite and arsenopyrite in fine, microscopic and submicroscopic particles. Pure arsenic gold ore is rare.
Graphite is an important carbonaceous non-metallic mineral. Its beneficiation methods mainly include flotation, gravity separation and electrostatic separation. Among them, flotation has become the most commonly used beneficiation method due to its wide applicability and excellent natural floatability of graphite.
In order to further improve the purity of quartz sand, a series of physical and chemical methods need to be used to deeply purify it. Acid leaching is a key process for removing metal impurities in quartz sand
As a non-metallic mineral that is easy to float, fluorite's flotation process becomes complicated because it often coexists with non-metallic minerals such as barite, quartz, calcite, and sulfide minerals such as galena, sphalerite, and pyrite.
Phosphorus is mainly found in phosphate ore in nature, so mining phosphate ore has become the main way to obtain phosphorus. With the development of mineral processing technology, we have evolved from manual sorting and panning to two major methods: physical and chemical beneficiation.
Phosphate ore is an important chemical raw material. It can be used to produce phosphate fertilizer, yellow phosphorus, phosphoric acid, phosphide and other phosphates. It is widely used in agriculture, medicine, food, matches, dyes, sugar, ceramics, national defense and other industrial sectors
