Lab Mineral Gravity Concentration Testing


Laboratory mineral gravity concentration testing is a method of separating minerals based on their density differences. It is widely used in the mining industry to separate valuable minerals from waste and has proven to be an effective technique for many types of ores. This process uses specially designed gravity separation equipment. Results obtained in gravity separation tests can provide valuable information on particle size distribution, recovery and process efficiency under controlled conditions.

Work Principle
Lab gravity concentration testing is used to determine the settling rate of particles in liquid or gaseous media. Grind the ore sample into a suitable size, and then put it into a small jig, spiral chute, shaker, centrifuge and other equipment. When the ore is subjected to centrifugal force, heavier particles settle to the bottom while lighter particles remain near the surface. To optimize this process, by using different equipment and parameters.

Main Testing Steps

Step 1: Sample Preparation

The representative ore sample is collected and crushed into small particles of uniform size. After crushing, the material is thoroughly mixed and divided into smaller samples for testing.

Step 2: Equipment Selection

The test equipment mainly includes lab jig, spiral chute, shaking table, centrifugal concentrator, etc. Select according to the nature of the material to be tested. Then determine the equipment specifications and key parameters to be evaluated during testing.

Step 3: Testing

Send the prepared materials into the equipment, run according to the predetermined parameters and conduct the lab testing.

Step 4: Analysis

The separated finished products are collected, usually with different concentrate grades. The finished product is analyzed using assay techniques to determine its composition and quality.

Step 5: Optimizating

During the process, test parameters or equipment settings can be modified to optimize separation performance, such as adjusting particle size, feed rate, water flow rate, inclination angle, etc.

Step 6: Reporting

Evaluate the separation efficiency, recovery rate, concentrate grade, etc. Record the overall technological process of mineral processing, the equipment and specifications, parameters and other relevant details required for laboratory testing.
