Tungsten and tin ore gravity separation

Tungsten and tin ore gravity separation

Tungsten ore and tin ore are two common non-ferrous metal minerals that have extensive applications in industrial production. However, due to the high amount of impurities in the ore, it is very difficult to directly extract high-purity tungsten and tin. Therefore, it is necessary to undergo gravity separation to separate impurities from the ore and improve the purity of tungsten and tin. This article will introduce the operational steps and precautions for tungsten and tin ore gravity separation.

1、 Operating steps for tungsten and tin ore gravity separation

1. Crushing and screening of ore

Firstly, it is necessary to crush and screen the tungsten and tin ores. The purpose of this step is to divide the ore into different particle sizes in preparation for subsequent beneficiation operations.

2. Reselection operation

Gravity separation is the core operation in the process of tungsten and tin ore gravity separation. During the re selection process, it is necessary to utilize the physical and chemical properties of minerals to separate impurities and improve the purity of tungsten and tin. The reselection operation usually includes the following steps:

(1) Flotation: Using the difference in mineral density to separate impurities from tungsten and tin ores.

(2) Gravity beneficiation: use the density difference of minerals to separate the impurities in tungsten ore and tin ore.

(3) Magnetic separation: Utilizing the magnetic differences of minerals to separate impurities from tungsten and tin ores.

3. Slag treatment

During the re selection process, a certain amount of slag will be generated. Slag contains some useful metal elements, such as iron, copper, etc. Therefore, it is necessary to treat the slag and extract useful metal elements from it to reduce environmental pollution.

Notes on tungsten and tin ore gravity separation

1. Pay attention to safety during the re selection process

During the re selection process, some chemical reagents and equipment are required. These chemical reagents and equipment may cause harm to the human body, so it is necessary to pay attention to safety. Operators need to wear protective gloves, masks, and other protective equipment to ensure their safety.

2. Environmental pollution needs to be controlled during the re selection process

A certain amount of wastewater and exhaust gas will be generated during the re selection process of . These wastewater and exhaust gases contain some harmful substances, such as heavy metal ions. Therefore, it is necessary to treat wastewater and exhaust gas to reduce environmental pollution.

3. Energy consumption needs to be controlled during the re selection process

During the gravity separation process, some equipment is required, such as flotation machines, gravity concentrators, magnetic separators, etc. These devices require a large amount of energy consumption, so it is necessary to control energy consumption and reduce its impact on the environment.

In short, tungsten and tin ore gravity separation is a very important industrial production process. By gravity separation, impurities in the ore can be separated and the purity of tungsten and tin can be improved. During the re selection operation, attention should be paid to safety, environmental pollution, and energy consumption issues to ensure the safety and environmental protection of the production process.
