Sand tin re selection test

Sand tin gravity separation test is a commonly used ore dressing method that can effectively separate sand tin ore, improve the grade and recovery rate of tin. This article will introduce the operating steps and precautions of sand tin gravity separation experiment, helping readers better understand and master this ore beneficiation technology.

1. Experimental Principles

The sand tin gravity separation experiment is to separate the sand tin ore through different density separation liquids, in order to improve the tin grade and recovery rate. In the experiment, the sand tin ore is first subjected to rough selection, intermediate selection, and selection steps to obtain selected tailings and selected tin concentrate. Then, the selected tailings and the selected tin concentrate are re selected separately, resulting in high-grade tin concentrate and low-grade tailings.

2、 Test steps

1. Sample preparation

Crush and grind the tin ore sample to prepare a sample that meets the test requirements.

2. Rough selection

Place the prepared sample into a roughing machine for roughing to obtain roughing tailings and roughing tin concentrate.

3. Successful selection

Place the rough selected tin concentrate into the intermediate separator for intermediate selection, and obtain the intermediate tailings and intermediate selected tin concentrate.

4. Selection

Put the selected tin concentrate into the concentrator for selection, and obtain the selected tailings and tin concentrate.

5. Reselection

Separate the selected tailings and the selected tin concentrate for gravity separation to obtain high-grade tin concentrate and low-grade tailings.

6. Analysis of experimental results

Calculate and analyze the grade and recovery rate of sand tin ore based on the experimental results, and evaluate the experimental effect.

3、 Precautions

1. During sample preparation, attention should be paid to the degree of fragmentation and grinding to ensure the uniformity of the sample and meet the test requirements.

During the testing process, attention should be paid to the operation and maintenance of each machine to ensure the normal operation of the test.

When calculating and analyzing the grade and recovery rate based on the experimental results, attention should be paid to the accuracy and reliability of the data to avoid errors.

IV. Conclusion

The sand tin gravity separation test is an effective ore dressing method that can improve tin grade and recovery rate, providing important technical support for the development and utilization of sand tin ore. During the experiment, attention should be paid to the operation and maintenance of each step to ensure the accuracy and reliability of the experiment.
