Phosphate ore is an important mineral resource. The purpose of phosphate ore dressing process is to improve the grade and recovery rate of phosphate ore, so as to efficiently utilize phosphate ore resources.
The main treatment methods for copper oxide ore include flotation, separation, leaching and combined methods. Among them, flotation is widely used because of its environmental protection, low cost and simple process.
Kaolin is an important industrial mineral raw material, widely used in ceramics, papermaking, coatings and other industries. In the production process of kaolin, iron removal is a key step, because iron impurities will affect the whiteness and application performance of kaolin.
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
