Gravity beneficiation test of seaside placer ore

With the continuous development of technology, ore beneficiation technology is also constantly innovating. Among them, gravity beneficiation technology is a relatively mature beneficiation method. Today, we will introduce a gravity beneficiation test method for coastal sand mines based on gravity beneficiation technology.

1、 Overview of coastal placers

Coastal placers refer to placers located near the coastline. This ore is mainly composed of quartz and heavy minerals, such as Magnetite, Ilmenite, Rutile, etc. Due to the complex composition of coastal placers, traditional beneficiation methods are not effective, so new technical means need to be adopted.

2、 Gravity beneficiation technology

Gravity beneficiation technology is a beneficiation method that utilizes the differences in specific gravity of different minerals to separate ores through the action of gravity. The principle is to place the ore on an inclined plane and use gravity to separate it into two parts: heavy minerals and light minerals. Heavy minerals slide down the slope, while light minerals rise along the slope, achieving separation.

3、 Test steps for gravity beneficiation of seaside placers

1. Collecting ore samples: Firstly, a certain number of ore samples need to be collected from coastal placers for testing.

2. Crushing ore: Crush the collected ore sample to make it uniform in size.

3. Design of beneficiation slope: Design a suitable beneficiation slope based on the properties of the ore. The angle and length of the beneficiation slope are important factors that affect the effectiveness of gravity beneficiation.

4. Conduct gravity beneficiation test: Place the crushed ore sample on the beneficiation slope, and adjust the slope angle and water flow rate to separate the ore sample into two parts: heavy minerals and light minerals.

5. Heavy mineral recovery: The separated heavy minerals are recovered for subsequent processing and utilization.

4、 Advantages of Gravity Beneficiation Test for Seashore Placer Mines

1. Good beneficiation effect: The composition of coastal placers is complex, and traditional beneficiation methods are ineffective. However, gravity beneficiation technology can effectively separate the ore into heavy and light minerals, improving the beneficiation effect.

2. Simple equipment: The equipment of gravity beneficiation technology is relatively simple and does not require a large amount of equipment investment, reducing costs.

3. Environmental protection and energy conservation: Gravity beneficiation technology does not require the use of chemicals and does not generate wastewater and waste gas, making it more environmentally friendly and energy-saving.

5、 Summary

The gravity beneficiation experiment of seaside placer ore is a new beneficiation method based on gravity beneficiation technology. This method has the advantages of good beneficiation effect, simple equipment, environmental protection and energy conservation. In practical applications, reasonable design and adjustment can be made based on the properties of the ore and the beneficiation requirements to achieve the best beneficiation effect.
