How to Use Dredge Pump to Get Silica Sand in Thailand?

Silica sand is a naturally occurring granular material composed mainly of silicon dioxide (SiO₂). It is commonly found in the form of fine particles and is produced through weathering, erosion, and sedimentation processes.

How about the Silica Resources in Thailand?

Thailand is rich in silica sand resources. Silica sand in Thailand is mainly distributed in the following areas:

Main distribution areas:

Sudan region:

Places such as Songkhla and Phuket contain high-purity silica sand, which is mainly used in construction and industry.

Central region:

Silica sand is also mined in places such as Pathum Thani and Rayong.

What is the Application of Silica Sand?

Thailand's silica sand is widely evaluated for construction materials, glass manufacturing, casting, and other industrial uses. Due to its quality, Thailand's silica sand is also competitive in the international market.

How to Get Silica Sand?

The process of extracting silica sand usually includes the following steps:

1. Exploration and Evaluation

Geological exploration: Determine the location, size and quality of silica sand deposits through geological survey and exploration.

Sample analysis: Samples are extracted for laboratory analysis to evaluate the silica content and impurity content.

2. Mining method

A Open-pit mining

A commonly used method, suitable for shallowly buried silica sand deposits. The silica sand is excavated directly by stripping away the top layer of soil. Use an excavator to remove soil and remove impurities from the surface. Use an excavator to collect the sand, then transport it to a conveyor belt and transport it to a suitable storage yard. This method is simple, but the personnel and machine costs are relatively expensive. As the excavation depth increases and rainwater increases during the rainy season, effective drainage is required.

B River sand mining:

In rivers or lakes, mechanical equipment is used to extract deposited silica sand.

There are currently 2 ways:

A: Silica sand will accompany iron ore sand, and generally the depth of deep ash exceeds 15m. A simple submersible sand pump is used to extract it with a high-pressure water gun.

B: Silica sand accompanies kaolin to form a sticky sand layer, which cannot be solved by ordinary methods. It is necessary to use a hydraulic suction dredger and then pump it out. Through the relay pump unit, long-distance transportation can also be achieved.

Underground mining: In some cases, underground mining may be required, but this is not common in silica sand mining.

3. Processing and handling

Cleaning: The extracted silica sand is cleaned to remove impurities and fine particles.

Screening: The silica sand is classified by particle size through screening equipment to meet different application requirements.

Drying: If necessary, dry to reduce moisture content.

4. Transportation and storage

Packaging: The processed silica sand is packaged, usually in bags or bulk.
