In today's increasingly depleted mineral resources, how to efficiently develop and utilize mineral resources is a problem that every mining practitioner faces. As a common mineral resource, the mining and utilization of placers have always been of great concern. However, due to the small particles of quartz sand in placers and the presence of many impurities, its utilization rate is not high. Therefore, the research and application of placer gravity separation technology is particularly important. This article will introduce a beach placer gravity separation experiment to explore an efficient method of placer utilization.

1、 Overview of the experiment

The samples for this experiment are from a coastal placer mine, where the main minerals are quartz sand and feldspar. The particle size of quartz sand is smaller and the impurity content is higher. The experiment aims to improve the utilization rate and quality of quartz sand through gravity separation technology, while reducing the content of impurities, providing technical support for the efficient utilization of sand ore.

2、 Test steps

海滨砂矿重选试验 1. Preparation of sand ore samples

Firstly, it is necessary to prepare sand ore samples. Crush, screen, and wash the sand ore samples to obtain fine powdered quartz sand with a particle size of 0.074mm or less, which is used as the raw material for the gravity separation test.

2. Determination of the re selection process flow

Determine the gravity separation process flow based on the characteristics of sand ore samples and experimental objectives. This test adopts the heavy medium beneficiation process, that is, quartz sand is immersed in heavy medium, and the density difference of heavy medium is used to separate quartz sand and impurities.

3. Operation of reselection test

Place the prepared quartz sand sample into the gravity separation equipment, add heavy media, set appropriate stirring time and intensity to separate the quartz sand and impurities. Then, the separated quartz sand is dried, screened, and other processes are carried out to obtain high-quality quartz sand products.

3、 Test results

The quality of quartz sand products obtained through re selection experiments has been significantly improved. The content of quartz sand has increased from 70% to over 90%, and the content of impurities has also been significantly reduced. The experimental results indicate that the heavy medium beneficiation process is an efficient gravity separation technology that can effectively improve the utilization rate and quality of sand ore.

4、 Conclusion

The application of gravity separation technology in this seaside sand ore gravity separation experiment has successfully improved the utilization rate and quality of quartz sand, providing technical support for the efficient utilization of sand ore. At the same time, the experimental results also indicate that the heavy medium beneficiation process is an efficient gravity separation technology that can be widely applied in the mining and utilization of placers.
