Gravity beneficiation process flow of Wolframite

Wolframite is one of the most important tungsten resources in the world. The mining and beneficiation process of Wolframite has always been the focus of mining workers. In the beneficiation process of Wolframite, gravity beneficiation process is a common beneficiation method. Its process flow is simple, cost is low, and recovery rate is high, so it is favored by mining workers. This paper will introduce the gravity beneficiation process of Wolframite in detail, hoping to provide some references for everyone.

1、 Overview of gravity beneficiation process of Wolframite

The gravity beneficiation process flow of Wolframite mainly includes several steps, such as ore crushing, grinding, gravity concentration and concentration. Among them, gravity concentration is the core link of gravity beneficiation process. Through gravity concentration, tungsten minerals in Wolframite can be separated from non-metallic minerals such as quartz, so as to improve tungsten grade. Below, we will provide a detailed introduction to these steps.

2、 Detailed explanation of gravity beneficiation process flow of Wolframite

1. Ore crushing

Ore crushing is the first step of Wolframite beneficiation. Its purpose is to crush the raw ore into Granularity suitable for grinding. Jaw crusher is usually used for ore crushing, and the Granularity of crushed ore is generally 10-20mm.

2. Grinding

Grinding is the second step of Wolframite beneficiation, which aims to grind the ore to a finer Granularity for subsequent gravity beneficiation. The common grinding equipment includes ball mill and rod mill, and the Granularity of ore after grinding is generally 0.074-0.2mm.

3. Reselection

Gravity separation is the core link of Wolframite gravity beneficiation process. Its purpose is to separate tungsten minerals from non-metallic minerals such as quartz in Wolframite through gravity separation, so as to improve tungsten grade. Gravity separation is usually carried out using equipment such as spiral separators, central cyclone separators, and shakers. The grade of tungsten concentrate after gravity separation is generally around 50% -70%.

4. Selection

Cleaning is the last step of Wolframite gravity beneficiation process, which aims to further improve the grade of tungsten concentrate and meet the requirements of industrial production. The commonly used selection equipment includes vibrating screens, centrifuges, air flotation separators, etc. The grade of tungsten concentrate after selection can reach over 80%.

3、 Summary

Through the detailed introduction of Wolframite gravity beneficiation process, we can see that gravity beneficiation process is a simple, low-cost and high recovery beneficiation method. In the process of Wolframite beneficiation, gravity beneficiation process has important application value and can provide strong support for Wolframite mining and beneficiation. Of course, different mining and ore characteristics can also have an impact on the selection of beneficiation processes, which need to be selected based on actual situations.
