White tin ore gravity separation test

White tin ore gravity separation test

In recent years, with the continuous improvement of people's awareness of environmental protection, the mining industry has gradually developed towards green environmental protection. White tin ore is a common mineral resource, but it contains a lot of impurities, which pose certain risks to the environment and human health. Therefore, how to effectively concentrate white tin ore is one of the urgent problems to be solved in the current mining industry.

We conducted a series of experiments to find a feasible method for white tin ore gravity separation. This article will provide a detailed introduction to our experimental process and results, as well as operational steps and precautions.

Test process

Firstly, we need to conduct preliminary screening and washing of the collected tin ore to remove large impurities and sediment. Next, we conducted gravity separation experiments on the samples of white tin ore, mainly using methods such as heavy medium beneficiation, flotation, and magnetic separation.

In the heavy medium beneficiation experiment, we used a medium density of 2.9g/cm ³ Separation of heavy media. Firstly, the white tin ore sample is crushed to a certain particle size, and then mixed with a heavy medium for sorting through a hydraulic classifier. After multiple experiments, we have determined the optimal proportion of heavy media and sorting conditions, and achieved good sorting results.

In the flotation experiment, we used the air flotation method for sorting. Crush the tin ore sample to a certain particle size, and then contact it with bubbles to separate it from water. After multiple experiments, we have determined the optimal bubble size and flotation conditions, and achieved good separation results.

In the magnetic separation experiment, we used the high gradient magnetic separation method for sorting. Crush the tin ore sample to a certain particle size, then mix it with magnetic materials and use a high gradient magnetic separator for sorting. After multiple experiments, we have determined the optimal proportion of magnetic materials and sorting conditions, and achieved good sorting results.

Test results

Through the experiments of the above three methods, we have achieved good results in the gravity separation of white tin ore. Among them, the effects of heavy medium beneficiation and flotation are relatively similar, resulting in higher tin grade and lower impurity content; The effect of magnetic separation is slightly inferior, but it still has a certain sorting effect for some difficult to remove magnetic impurities.

Operating Steps

1. Conduct preliminary screening and washing of the collected tin ore to remove large impurities and sediment.

2. Conduct gravity separation tests on the samples of white tin ore, using methods such as heavy medium beneficiation, flotation, and magnetic separation.

3. In heavy medium beneficiation experiments, a medium density of 2.9g/cm is used ³ Separation of heavy media.

4. In the flotation experiment, the air flotation method is used for sorting.

5. In the magnetic separation experiment, the high gradient magnetic separation method is used for sorting.

6. Determine the optimal sorting method and conditions based on the experimental results.

matters needing attention

During the testing process, it is important to maintain the cleanliness and safety of the laboratory.

2. When conducting heavy medium beneficiation experiments, attention should be paid to controlling the density of the medium and separation conditions to avoid excessive or insufficient separation.

3. During the flotation test, pay attention to controlling the bubble size and flotation conditions to avoid too large or too small foam.

When conducting magnetic separation experiments, attention should be paid to controlling the proportion of magnetic materials and sorting conditions to avoid the occurrence of magnetic impurities not being sorted.

epilogue

Through this white tin ore gravity separation experiment, we have achieved good separation results and operational steps. In future mining production, we will continue to explore more environmentally friendly and efficient ore gravity separation methods, making contributions to the development of green mining.
