Gravity beneficiation test of tin tailings

Gravity beneficiation test of tin tailings

Tin tailings refer to the waste produced in the process of extracting tin from tin ore mountains. After processing these waste materials, useful metal and non-metallic minerals can be obtained. Among them, gravity beneficiation is a commonly used processing method. This article will introduce the specific steps and precautions for the gravity beneficiation test of tin tailings.

1、 Preparation before testing

Before conducting the gravity beneficiation test of tin tailings, some preparatory work needs to be done. Firstly, it is necessary to collect samples of tin tailings and conduct chemical analysis to determine their composition and content. Secondly, it is necessary to prepare various experimental equipment, including vibrating screens, spiral separators, gravity concentrators, etc. Finally, a detailed experimental plan needs to be developed, including the steps of the experiment, parameter settings, and data recording.

2、 Test steps

1. Vibration screening

Firstly, the tin tailings sample is graded through a vibrating screen. The purpose of this step is to divide the raw materials into different particle size levels for subsequent processing. Usually, the mesh size of the vibrating screen is 2mm, 5mm, 10mm, etc.

2. Spiral sorting

Next, the tin tailings samples with different particle sizes separated by vibration screening are processed using a spiral sorting machine. The purpose of this step is to separate minerals with different particle sizes for subsequent gravity beneficiation processing. Normally, the spiral diameter of a spiral sorting machine is 300mm and the spiral speed is 30r/min.

3. Gravity beneficiation

Finally, the tin tailings samples that have undergone spiral sorting treatment are processed through a gravity concentrator. The purpose of this step is to separate minerals of different densities to obtain useful metallic and non-metallic minerals. Normally, the length and width of the beneficiation tank in a gravity concentrator are 2000mm and 500mm, with a tilt angle of 5 degrees.

3、 Precautions

When conducting gravity beneficiation tests on tin tailings, the following points need to be noted:

1. Sample selection: Tin tailings samples should be representative and reflect the actual production situation as much as possible.

2. Equipment selection: Choosing appropriate equipment can better adapt to the needs of the experiment.

3. Parameter setting: Reasonably set various parameters according to the needs of the experiment to achieve the best experimental effect.

4. Data recording: During the experiment, it is necessary to carefully record all data for subsequent analysis and summary.

In summary, the gravity beneficiation test of tin tailings is a commonly used treatment method that can effectively extract useful metallic and non-metallic minerals. When conducting experiments, it is necessary to carefully develop a test plan, select appropriate equipment and parameters, in order to achieve the best test results.
