Tungsten ore is an important metal ore, and due to its importance in industrial production, the mining and sorting of tungsten ore has always been a key research field in the mining industry. In the process of tungsten ore sorting, a series of sorting methods need to be adopted to improve the grade and recovery rate of tungsten ore. This article will introduce several common methods for tungsten ore separation.
heavy medium sorting method
The heavy medium separation method is a separation method based on density difference. It divides ores into different density grades by using the density difference of heavy medium. In tungsten ore sorting, the commonly used heavy media are magnetic liquid, Baryte, heavy liquid iron, etc. The heavy medium separation method is suitable for ores with particle size greater than 0.5mm and can achieve high separation efficiency.
Flotation method
The 
flotation method is a separation method based on physical and chemical properties, which adsorbs reagents on the surface of the ore to interact with water, thereby achieving the separation of the ore. In the selection of tungsten ore, commonly used flotation reagents include xanthate, black powder, copper green, etc. The flotation method is suitable for ores with particle size less than 0.5mm and can achieve high separation efficiency.
Gravity magnetic separation method
The gravity magnetic separation method is a separation method based on magnetism and gravity, which adsorbs magnetic substances on the surface of the ore and utilizes the magnetism and gravity of the magnetic substances to classify the ore into different levels. In the selection of tungsten ore, commonly used magnetic substances include iron oxide, iron oxide magnetic powder, etc. The gravity magnetic separation method is suitable for ores with particle size less than 0.5mm and can achieve high separation efficiency.
Reselection method
Gravity separation method is a gravity based separation method that divides ore into different grades by utilizing the difference in gravity of the ore. In tungsten ore sorting, commonly used gravity separation equipment includes gravity separators, spiral separators, etc. The gravity separation method is suitable for ores with particle size greater than 0.5mm and can achieve high separation efficiency.
Magnetic separation method
Magnetic separation method is a magnetic based separation method that uses the magnetism of magnetic substances on the surface of the ore to classify the ore into different grades. In the selection of tungsten ore, commonly used magnetic substances include iron oxide, iron oxide magnetic powder, etc. The magnetic separation method is suitable for ores with particle size less than 0.5mm and can achieve high separation efficiency.
In summary, there are many methods for tungsten ore sorting, each with its applicable ore size and sorting effect. In practical applications, it is necessary to select appropriate sorting methods based on the properties and sorting requirements of the ore to improve the grade and recovery rate of tungsten ore.
