Tungsten ore beneficiation process flow

Tungsten ore beneficiation process flow

Tungsten ore is an important metal mineral resource widely used in aviation, aerospace, electronics, chemical and other fields. The mining and beneficiation process of tungsten ore is crucial for improving the grade and recovery rate of tungsten ore. This article will introduce the operating steps and precautions of the tungsten ore beneficiation process flow.

1、 Overview of tungsten ore beneficiation process flow

The tungsten ore beneficiation process includes steps such as ore crushing, grinding, flotation, gravity separation, and selection. Among them, flotation is the most critical step in tungsten ore beneficiation, which directly affects the grade and recovery rate of tungsten ore. The main purpose of the tungsten ore beneficiation process is to separate impurities and useful components from tungsten ore, thereby improving the grade and recovery rate of tungsten ore.

2、 Operating steps of tungsten ore beneficiation process flow

1. Ore crushing

The purpose of tungsten ore crushing is to break the raw ore into appropriate particle sizes, which facilitates the subsequent beneficiation process. Ore crushing is usually carried out using equipment such as jaw crushers, cone crushers, and roller crushers.

2. Grinding

The purpose of tungsten ore grinding is to further refine the broken particles of the ore and improve flotation efficiency. Grinding is usually carried out using equipment such as ball mills, rod mills, and AG mills.

3. Flotation

The purpose of tungsten ore flotation is to separate useful components and impurities from tungsten ore, thereby improving the grade and recovery rate of tungsten ore. Generally, Chalcopyrite, Pyrite and brass cobalt ore are used as collectors in flotation to separate tungsten ores.

4. Reselection

The purpose of tungsten ore gravity separation is to further separate impurities from the flotation tungsten ore, improve the grade and recovery rate of tungsten ore. Gravity separation is usually carried out using equipment such as heavy medium separation, heavy liquid separation, and centrifugal separation.

5. Selection

The purpose of tungsten ore selection is to further separate impurities from the tungsten ore after gravity separation, thereby improving the grade and recovery rate of tungsten ore. Selection is usually carried out using equipment such as gravity beneficiation, magnetic separation, and electric separation.

3、 Precautions for tungsten ore beneficiation process flow

1. In the process of ore crushing and grinding, appropriate crushing and grinding equipment shall be selected according to different ore characteristics to avoid excessive or insufficient crushing.

During the flotation process, appropriate collectors and dosage should be selected based on the characteristics of the ore and flotation test results to ensure flotation efficiency and recovery rate.

3. In the process of re selection and selection, appropriate separation equipment and process flow should be selected based on the characteristics of the ore and the results of beneficiation tests to ensure separation efficiency and recovery rate.

In the tungsten ore beneficiation process, strict control should be exercised over parameters such as pH value, concentration, and temperature of the slurry to ensure the stability and controllability of the beneficiation process.

In short, the tungsten ore beneficiation process is a complex task that requires selecting appropriate equipment and process flow based on the characteristics and process requirements of the ore, and strictly controlling the operating parameters of each link to ensure the grade and recovery rate of the tungsten ore.
