Tungsten tin beneficiation method

Tungsten tin beneficiation method

Tungsten tin is an important metal mineral resource widely used in aviation, military industry, electronics, communication and other fields. The tungsten tin beneficiation method refers to the process of selecting, separating, and purifying tungsten tin ores. This article will introduce some common tungsten tin beneficiation methods and operating steps.

1、 Reselection method

The gravity separation method refers to the method of separating minerals by utilizing their physical and chemical properties. This method is suitable for minerals with obvious characteristics such as different mineral densities, colors, and magnetic properties. The commonly used gravity separation equipment includes gravity concentrators, flotation machines, magnetic separators, etc. The operation steps are as follows:

1. Crush the ore to a certain particle size, usually 0.5-3 millimeters.

2. Feed the ore into a gravity concentrator and use gravity to separate the ore.

3. Feed the ore separated by the gravity concentrator into the flotation machine and use bubble adsorption to separate the ore.

4. Feed the ore separated by the flotation machine into the magnetic separator, and use the magnetic effect to separate the ore.

5. Finally, tungsten tin ore and waste are obtained.

2、 Chemical method

Chemical method refers to the method of separating minerals by utilizing their chemical properties. This method is suitable for minerals with significant differences in chemical properties. The commonly used chemical methods include leaching, precipitation, extraction, etc. The operation steps are as follows:

1. Crush the ore to a certain particle size, usually 0.5-3 millimeters.

2. Send the ore into a leaching tank and add chemical reagents for leaching.

3. Send the leaching solution into a sedimentation tank and use sedimentation to separate the minerals.

4. Send the precipitated minerals into an extraction tank and use an extractant to separate the minerals.

5. Finally, tungsten tin ore and waste are obtained.

III. Comprehensive method

Comprehensive method refers to the method of combining multiple mineral processing methods. This method is suitable for minerals with complex mineral properties that are difficult to separate. The commonly used comprehensive methods include gravity separation chemical method, flotation chemical method, etc. The operation steps are as follows:

1. Crush the ore to a certain particle size, usually 0.5-3 millimeters.

2. Feed the ore into a gravity concentrator and use gravity to separate the ore.

3. Feed the ore separated by the gravity concentrator into the flotation machine and use bubble adsorption to separate the ore.

4. Send the ore separated by the flotation machine into a leaching tank and add chemical reagents for leaching.

5. Feed the leaching solution into a sedimentation tank and use sedimentation to separate the minerals.

6. Send the precipitated minerals into an extraction tank and use an extractant to separate the minerals.

7. Finally, tungsten tin ore and waste are obtained.

In summary, there are various methods for tungsten tin beneficiation, including gravity separation, chemical method, comprehensive method, etc. The specific method to be selected depends on the physical and chemical properties of the ore. During operation, attention should be paid to protecting the environment, saving resources, improving beneficiation efficiency and product quality.
