Seashore sand tin is an important non-metallic mineral resource widely used in fields such as architecture, glass, ceramics, and chemical engineering. However, there are many technical difficulties in the mining and beneficiation process of coastal sand tin, which require professional technical personnel to solve. This article will introduce the operational steps and precautions for selecting seaside sand tin technology, helping readers better understand this field.
1、 Mineral processing principle
beneficiation refers to the process of separating useful and useless minerals mixed in ore through physical, chemical, or other methods. The principle of selecting seaside sand tin is to use the differences in its physical and chemical properties to separate it using methods such as gravity separation, flotation, and magnetic separation. Among them, gravity separation refers to the use of mineral density differences for separation; Flotation refers to the use of differences in the hydrophilicity and hydrophobicity of minerals for separation; Magnetic separation refers to the use of magnetic differences in minerals for separation.
2、 Beneficiation operation steps
1. Crushing: Crush the collected coastal sand tin to meet the particle size requirements for beneficiation.
2. Grinding: Grinding the crushed ore to make its fineness suitable for beneficiation operations.
3. Gravity separation: Use a gravity separator to separate the heavy minerals from the ore. The gravity separator is a kind of equipment that uses mineral density difference for separation. Its working principle is to put ore into water, use the buoyancy of water to float light minerals, and sink heavy minerals into the water bottom.
4. Flotation: Flotation is performed on the re selected ore, utilizing the differences in hydrophilicity and hydrophobicity of the minerals for separation. Flotation machine is a kind of equipment that uses the surface properties of minerals for separation. Its working principle is to put ores into water and add reagents to form foam on the surface of useful minerals and sink hydrophobic minerals into the water bottom.
5. Magnetic separation: Magnetic separation is performed on the ore after flotation, utilizing the magnetic differences of the minerals for separation. A magnetic separator is a device that uses mineral magnetism for separation. Its working principle is to place the ore in a magnetic field, and use the difference in mineral magnetism to adsorb magnetic minerals onto the magnetic poles. Non magnetic minerals flow through the magnetic poles.
1. During the beneficiation process, it is necessary to control the dosage and type of reagents to ensure the beneficiation effect.
2. Mineral processing equipment requires regular maintenance and repair to ensure its normal operation.
During the beneficiation process, attention should be paid to environmental issues to avoid pollution to the environment.
The selection of seaside sand tin technology is an important technical field that requires professional technical personnel to operate. This article introduces the principle, operating steps, and precautions of mineral processing, hoping that readers can have a deeper understanding of the technology of selecting coastal sand tin.Seashore Sand Tin Selection Technology
