Process flow of tungsten tin ore beneficiation

Tungsten tin ore is an important metal ore, containing high levels of tungsten and tin elements, and is an important raw material for manufacturing tungsten steel and tin alloys. The beneficiation process of tungsten tin ore refers to the process of separating useful minerals from waste rock. This article will introduce the operating steps and precautions of the tungsten tin ore beneficiation process flow.

1、 Overview of tungsten tin ore beneficiation process flow

The beneficiation process of tungsten tin ore includes steps such as crushing, grinding, flotation, and gravity separation. Among them, flotation and gravity separation are the core steps and the most critical links of tungsten tin ore beneficiation.

2、 Operation steps of tungsten tin ore beneficiation process flow

1. Crushing

After crushing the tungsten tin ore, the particle size of the ore is moderate, making it easy for subsequent grinding and flotation. There are various ways of crushing, commonly used being jaw crushers and cone crushers.

2. Grinding

grinding is the process of further refining the crushed ore to make its particle size more uniform. There are two types of grinding methods: dry grinding and wet grinding. Dry grinding is suitable for ores with smaller particles, while wet grinding is suitable for ores with larger particles.

3. Flotation

Flotation is the process of separating useful minerals from waste ore after grinding. The principle of flotation is to utilize the differences in physical and chemical properties of mineral surfaces to raise useful minerals and bubbles to the liquid surface, thereby achieving separation. The conditions for flotation include the type and dosage of reagents, stirring strength, bubble size and quantity, etc.

4. Reselection

Gravity separation is the process of further purifying useful minerals from the flotation concentrate after flotation. The principle of re selection is to separate useful minerals from waste rocks by utilizing differences in physical properties such as gravity, centrifugal force, magnetism, and electricity. The conditions for re selection include the type and specifications of beneficiation equipment, the level of beneficiation, etc.

3、 Notes on the beneficiation process of tungsten tin ore

1. Each step in the tungsten tin ore beneficiation process should be strictly controlled to ensure standardized operation and avoid misoperation.

During the flotation and gravity separation processes, attention should be paid to controlling the type and dosage of reagents to prevent improper use of reagents from affecting the beneficiation effect.

During the beneficiation process, attention should be paid to protecting the environment and avoiding pollution caused by the discharge of wastewater and waste residue.

4. In the selection and specifications of beneficiation equipment, it should be determined based on the properties of the ore and the requirements of beneficiation level, to avoid poor beneficiation effect caused by improper equipment.

In short, the beneficiation process of tungsten tin ore is a very important work, which is of great significance for improving the quality and development value of tungsten tin ore. Only by strictly following the operating steps and precautions can we ensure the maximization of beneficiation effect and production efficiency.
