How to screen out copper and tungsten mines

Copper and tungsten ores are common metal ores with extensive applications in industry and production. However, in order to accurately separate copper and tungsten ores from the mixed ore, a series of screening operations are required. In this article, we will provide a detailed introduction to the screening methods for copper and tungsten mines to help readers better understand this process.

1、 Characteristics of Copper and Tungsten Mines

Before conducting screening, we need to understand the characteristics of copper and tungsten mines. The main component of copper ore is copper. Common copper ores include Chalcopyrite, Pyrite, Hematite, etc. Tungsten ore is mainly composed of tungsten, and common tungsten ores include Wolframite, Scheelite, stannite, etc. The density of copper ore and tungsten ore is different, and the density of copper ore is 8.9-9.3g/cm ³， And the density of tungsten ore is 18.5-19.3g/cm ³， This provides a foundation for subsequent filtering operations.

2 II. Screening Methods for Copper and Tungsten Mines

1. Magnetic separation method

Magnetic separation is a commonly used method for screening copper and tungsten ores. This method utilizes the characteristics of magnetic materials to separate copper and tungsten minerals from other minerals. Copper and tungsten ores have weak magnetic properties and usually require magnetic separation in high intensity magnetic fields. Magnetic separators are usually composed of magnetic induction coils, magnets, and sorting slots, which can be adjusted based on the magnetic strength of the ore.

2. Reselection method

The gravity separation method is a method of separating minerals by gravity. Copper ore and tungsten ore have different densities and can be separated by gravity separation. The gravity separator is usually composed of a feeding trough, a vibrator, a sieve, and a discharge trough, which can be adjusted according to the density of the ore.

3. Flotation method

Flotation method is a method of separating minerals by their surface properties. Copper and tungsten ores have different surface properties and can be separated by flotation. Flotation machine is usually composed of feed chute, agitator, gas supply, foam separator and discharge chute, which can be adjusted according to the surface properties of ores.

3、 Screening process for copper and tungsten mines

The screening process for copper and tungsten ores typically includes the following steps:

1. Coarse screening: The raw ore is separated into larger stones and smaller ore particles through coarse screening.

2. Magnetic separation: The ore is separated from copper and tungsten ore through a magnetic separator.

3. Gravity separation: The ore is separated from copper and tungsten ore through a gravity separator.

4. Flotation: The ore is separated from copper and tungsten ore through a flotation machine.

5. Selection: The separated copper and tungsten ores are selected to obtain pure copper and tungsten.

4、 Precautions

During the screening process of copper and tungsten mines, the following issues need to be noted:

1. Selection of filter: select appropriate filter according to different ore characteristics to improve screening efficiency and precision.

2. Adjustment of screening conditions: Adjust the screening conditions based on different ore characteristics to achieve the best screening effect.

3. Equipment maintenance: Regularly inspect and maintain the screening equipment to ensure its normal operation and long-term use.

In a word, the screening of copper ore and tungsten ore is a complex process, and appropriate screening methods and equipment need to be selected according to different ore characteristics. Through reasonable screening processes and operations, copper and tungsten ores can be effectively separated, improving the efficiency and quality of industrial production.
