Gravity beneficiation test of tungsten tin tailings

Tungsten tin tailing is the waste produced in the mining process of tungsten Xikuangshan Mine, which contains a certain amount of valuable metal elements such as tungsten and tin. The comprehensive utilization of tungsten tin tailings has always been one of the difficulties in the later stage of mining, and the gravity beneficiation technology of tungsten tin tailings is currently a relatively mature treatment method. This article will introduce the operational steps and test results of the gravity beneficiation test for tungsten tin tailings.

1. Test Purpose

The purpose of this experiment is to explore the applicability of gravity beneficiation technology for tungsten tin tailings and optimize operating parameters, providing reference for subsequent engineering applications.

II. Experimental Principles

The gravity beneficiation technology of tungsten tin tailings is a method of separating useful and useless minerals in the ore through the action of gravity. Under the action of gravity field, minerals with higher density will settle down, while minerals with lower density will float on top. By adjusting the size and direction of the gravity field, the separation of minerals with different densities in the ore can be achieved.

3、 Test steps

1. Sample preparation

Firstly, a certain amount of tungsten tin tailings samples need to be collected from the mine, and processed through crushing, screening, and other processes to prepare samples that meet the test requirements.

2. Test equipment

The equipment used in this experiment includes a gravity concentrator, vibrating screen, water pump, water tank, etc.

3. Test operation

Add the prepared sample to the gravity concentrator and achieve the separation of minerals with different densities in the ore by adjusting the size and direction of the gravity field. The separated minerals are screened through a vibrating screen to obtain minerals with different particle sizes. Finally, the mineral samples were sent to the laboratory for laboratory analysis and the test results were obtained.

4、 Test results

After testing, we obtained the following results:

1. The gravity beneficiation technology for tungsten tin tailings has a high recovery rate of over 90% for tungsten and tin.

2. During the experiment, it was found that the operating parameters of the gravity concentrator have a significant impact on the test results and require optimization and adjustment.

Through the analysis of the experimental results, we have drawn some conclusions and suggestions that can provide reference for future engineering applications.

Conclusion and Outlook

This experiment has demonstrated the applicability and advantages of gravity beneficiation technology for tungsten tin tailings, while also identifying some problems and shortcomings. We will continue to conduct in-depth research and exploration of this technology, further optimize operating parameters and equipment structure, and improve the comprehensive utilization efficiency of tungsten tin tailings.
