1、 Overview

Silicon ore mainly contains quartz and chalcedony, and the content of silicon dioxide is also high. In order to improve the comprehensive utilization rate of silicon ore, mineral processing is necessary. What are the beneficiation equipment for silicon ore? In order to solve this problem, Jinqiang has configured a set of efficient silica separation equipment based on the properties of silica ore. The following is a brief introduction to several important equipment in silica separation equipment.

2、 Silica separation equipment

1. Jaw crusher - crushing equipment.

The jaw crusher is mainly used for the primary crushing operation of raw silicon ore, mainly for crushing silicon blocks into uniformly sized particles. The crushed silicon ore fully meets the requirements for the feed inlet of the next equipment ball mill. This equipment has the characteristics of high crushing efficiency, easy operation, large crushing ratio, and long service life. It is a good silicon ore crushing equipment.

2. Ball mill - grinding equipment.

A ball mill is used to grind silica ore. Compared to other grinding equipment on the market, this equipment has the following advantages.

A. All components are processed with good steel, and the equipment has strong wear resistance and impact resistance, which not only prolongs the replacement cycle of vulnerable parts, but also extends the service life of the equipment.

b. The main bearing adopts large diameter double row self-aligning roller bearings, reducing friction and energy consumption during the working process.

c. The operation is very convenient, the working process is pollution-free, and to a certain extent, the surrounding environment is improved, meeting national environmental standards.

d. Due to the lack of inertial impact, the equipment operates more stably, improving the grinding efficiency of the equipment, and the particle size of the silicon ore product is also very uniform.

3. Flotation machine - Flotation equipment.

The use of a flotation machine as a flotation operation for silica ore has the following advantages in improving concentrate grade.

A. The processing capacity of silicon ore is large, with a unit time processing capacity of 3-4 times that of a general flotation machine, and the equipment energy consumption is also very low.

b. Easy to maintain, the flotation cell has no operating components, a compact internal structure, and a relatively small footprint.

c. The degree of automation is also very high, saving time and effort, saving a lot of costs for silicon ore processing plants, and the wear resistance of various components is also very good.

d. There is almost no noise during the construction process, with high flotation efficiency and no restrictions on the construction environment.

4. Dryer - Drying equipment.

The dryer is mainly used for drying the silica slurry after flotation. This equipment has high drying efficiency and is easy to operate and maintain. In addition, it also has characteristics such as stable operation, energy conservation and consumption reduction, affordable price, and low-carbon environmental protection. It is a very good silicon ore drying equipment.

3、Silica separation and purification process flow

There are many processes for silica separation and purification, which are generally determined based on the variety, content, occurrence status, and product quality requirements of impurities in silica. Common silica separation and purification processes are as follows:

（1） Wiping - Grading, Desliming

During the process of weathering, accumulation, and mineralization of silica, many clay based and iron based mineral deposits form cementitious or cohesive deposits on the surface of silica. The commonly used process for purifying this type of silica is to use wiping, grading, and desliming processes to remove clay impurities, mineral deposits, muddy iron, and some thin film iron. This process is generally used as a pre-treatment process before the selection of raw ore to effectively remove muddy impurities from mineral deposits.

（2） Wiping Desliming Magnetic Separation

Generally speaking, common impurity mineral deposits in silica, such as weak magnetic minerals such as limonite, tourmaline, hematite, and biotite, can only be removed by using magnetic separation technology. In practical production, wet strong magnetic machines are often used for separation.

（3） Rod grinding wiping desliming magnetic separation flotation acid leaching

After wiping, magnetic separation, and flotation separation, the low impurity mineral particles (including monomers and aggregates) in the raw silica ore have been basically eradicated and cleaned. The purity of silica can generally reach 99.5% -9.9%, which is basically satisfactory for most industrial uses of silica. However, in order to further develop into ultra-high purity silica, it is necessary to perform acid leaching treatment on impurities that are connected on the surface of silica particles in a mottled and inclusion manner. Depending on the requirements of different industrial uses for different impurity mineral deposits (Fe, AL, Ti, Cr) of silica, different concentrations and ratios of mixed acid leaching treatment must be carried out. For example, a certain silica rock ore has a silicon dioxide content of 99.76%, containing fine inclusions, and the primary impurity mineral deposits Fe, AL Ti and others exist in the form of clay deposits and iron oxides. After the process of rod grinding, wiping, desliming, magnetic separation, flotation, and acid leaching, high-purity silica with a silicon dioxide content of over 99.99% is obtained.
