Beneficiation technology of copper tungsten ore

Copper tungsten ore is an important metal ore that has received widespread attention due to its widespread applications in military, aviation, aerospace, and other fields. However, the beneficiation technology of copper tungsten ore is a relatively complex problem. This article will introduce the beneficiation technology of copper tungsten ore and its operating steps.

1、 Beneficiation technology of copper tungsten ore

The beneficiation technology of copper tungsten ore mainly includes three methods: gravity separation, flotation, and chemical beneficiation.

1. Reselection

Gravity separation is a common method in copper tungsten ore beneficiation. The principle of this method is to separate minerals by gravity according to the density difference of minerals. Gravity concentration mainly includes two methods: heavy medium beneficiation and Baryte beneficiation.

Heavy medium beneficiation is to put ore into heavy medium and separate minerals through density difference of medium. Baryte beneficiation is to put ore into Baryte and separate minerals through the difference of crystal density.

2. Flotation

Flotation is an important method in copper tungsten ore beneficiation. The principle of this method is to separate minerals through the action of bubbles based on their surface properties. Flotation mainly includes two methods: direct flotation and reverse flotation.

Direct flotation is the process of placing ore into a flotation cell and separating the minerals through the action of bubbles. Reverse flotation is the process of placing an ore into a flotation cell, first flotation non valent minerals, and then flotation valence minerals.

3. Chemical beneficiation

Chemical beneficiation is a new method in copper tungsten ore beneficiation. The principle of this method is to separate minerals through chemical reactions based on their surface properties. Chemical beneficiation mainly includes three methods: oxidation leaching, sulfide leaching, and cyanide leaching.

The oxidation leaching method involves placing the ore in an oxidant and separating the minerals through an oxidation reaction. The sulfurization leaching method involves placing the ore in a sulfurization agent and separating the minerals through a sulfurization reaction. The cyanide leaching method involves placing the ore in a cyanide agent and separating the minerals through a cyanide reaction.

2、 Operation steps of copper tungsten ore beneficiation technology

The operational steps of copper tungsten ore beneficiation technology mainly include ore crushing, ore grinding, gravity separation, flotation, and chemical beneficiation.

1. Ore crushing

Ore crushing is the first step in copper tungsten ore beneficiation. Ore crushing is mainly carried out using equipment such as jaw crushers, cone crushers, and impact crushers.

2. Ore grinding

Ore grinding is the second step in copper tungsten ore beneficiation. Ore grinding is mainly carried out using equipment such as ball mills, short end cone mills, and roller mills.

3. Reselection

Gravity separation is the third step in copper tungsten ore beneficiation. Gravity concentration mainly includes two methods: heavy medium beneficiation and Baryte beneficiation.

4. Flotation

flotation is the fourth step in copper tungsten ore beneficiation. Flotation mainly includes two methods: direct flotation and reverse flotation.

5. Chemical beneficiation

Chemical beneficiation is the final step in copper tungsten ore beneficiation. Chemical beneficiation mainly includes three methods: oxidation leaching, sulfide leaching, and cyanide leaching.

3、 Summary

The beneficiation technology of copper tungsten ore is a relatively complex problem that requires multiple methods to be used. Gravity separation, flotation, and chemical beneficiation are the three main methods in copper tungsten ore beneficiation, each of which includes multiple specific operational steps. In practical operation, it is necessary to select appropriate beneficiation techniques and operating steps based on the specific situation of the ore to achieve the optimal beneficiation effect.
