Tungsten tin gravity separation process flow

Tungsten tin alloy is an important material widely used in fields such as electronics, aerospace, and chemical engineering. However, in the production process of tungsten tin alloy, due to limitations in raw materials and process conditions, some quality problems often occur, such as impurities and coarse grains. In order to improve the quality of tungsten tin alloy, it is necessary to undergo re selection treatment. This article will introduce the tungsten tin gravity separation process and its operating steps.

I. Tungsten Tin Gravity Separation Process Flow

The tungsten tin gravity separation process mainly includes grinding, flotation, gravity separation, and selection processes. Among them, grinding and flotation are the pre processing of tungsten tin gravity separation, mainly used to separate impurities and useful minerals from the raw materials; Re selection and selection are the core links of tungsten tin re selection, mainly used to improve the grade and recovery rate of tungsten tin alloys.

1. Grinding

Grinding is the process of grinding raw materials to a certain particle size, with the aim of improving flotation efficiency. Grinding is generally carried out using a ball mill, and the particle size of the ore after grinding should be controlled below 0.074mm.

2. Flotation

Flotation is the process of separating raw materials after grinding, with the aim of separating useful minerals and impurities. Flotation is generally carried out using air flotation or reagent flotation methods. In the flotation process, it is necessary to select appropriate reagents and flotation conditions based on the physical and chemical properties of minerals to improve flotation efficiency.

3. Reselection

Gravity separation is the process of separating useful minerals after flotation, with the aim of improving the grade of tungsten tin alloys. Re-selection is generally carried out using the heavy medium sorting method or the vibration sorting method. In the process of gravity separation, it is necessary to select appropriate heavy media and separation conditions based on the density and particle size of minerals to improve the gravity separation effect.

4. Selection

Selection is the process of purifying useful minerals after re selection, with the aim of improving the purity of tungsten tin alloys. Selection is generally carried out using methods such as flotation, chemical leaching, or electrolysis. In the selection process, it is necessary to select appropriate purification methods and conditions based on the chemical properties and preparation requirements of minerals to improve the selection effect.

2、 Operating Steps

1. Grinding operation steps

(1) Feed the raw ore into a ball mill for grinding, and the grinding time should be controlled within 2-4 hours.

(2) Screen the ground ore and collect the ore with a particle size less than 0.074mm.

2. Flotation operation steps

(1) Send the ground ore into the flotation tank, add an appropriate amount of reagents and water, and stir.

(2) Inject air or nitrogen into the flotation cell to float useful minerals in the ore and sink impurities.

(3) Collect useful minerals after flotation, and dispose of impurities.

3. Steps for reselection operation

(1) Feed the useful minerals after flotation into the gravity separation tank, add heavy medium and water, and stir.

(2) Adjust the density and flow rate of the heavy medium based on the density and particle size of the minerals, so that useful minerals settle to the bottom.

(3) Collect the useful minerals after re selection, and dispose of the waste.

4. Selected operation steps

(1) Send the useful minerals after re selection into the selection tank, add an appropriate amount of reagents and water, and stir.

(2) Select appropriate purification methods and conditions based on the chemical properties and preparation requirements of the minerals, and perform selective treatment.

(3) Collect the selected useful minerals and dispose of the waste.

III. Summary

The tungsten tin gravity separation process is an important process that separates impurities and useful minerals from raw materials, improving the grade and recovery rate of tungsten tin alloys. Grinding, flotation, gravity separation, and selection are the main steps of tungsten tin gravity separation. It is necessary to select appropriate reagents and flotation conditions based on the physical and chemical properties of the minerals to improve the flotation effect. During the operation process, it is necessary to strictly control the parameters and conditions of each link to ensure the quality and preparation efficiency of tungsten tin alloy.
