Sphalerite beneficiation equipment and beneficiation process
Sphalerite is a typical sulfide ore. It is mainly composed of iron and zinc. It has a variety of colors, generally brown, light yellow, reddish brown, black, etc. It is used in chemical, metallurgy, environmental protection, glass and other industrial fields The uses are very wide.
Sphalerite is rich in valuable elements. In order to improve the comprehensive recovery and utilization rate of sphalerite, it is usually necessary to perform mineral processing on sphalerite.
Sphalerite beneficiation process
1. Jaw crusher
Jaw crusher is a crucial crushing equipment in the beneficiation process of sphalerite. It can crush sphalerite into particles of reasonable size, thus laying the foundation for the further processing of sphalerite. The big advantage of our company’s jaw crusher is that it is very flexible and can crush any type of sphalerite. The processing capacity of sphalerite is very large. It is a better choice for sphalerite crushing equipment.
2. Ball mill
Ball mill is a kind of sphalerite grinding equipment with a wide range of applications on the market. It has advantages that the same type of equipment in the market cannot surpass in terms of structure, quality and efficiency, mainly in the following aspects:
(1) The structure is more advanced: the overall structure design of the ball mill is very novel and advanced, and the technical parameters are designed very reasonable. Not only the volume is reduced to one-third of the original, but the weight is also reduced by more than half, and the operation and maintenance work are very good. Simple and easy.
(2) The quality is more reliable: All parts are made of high-quality wear-resistant materials, and the wear resistance and corrosion resistance are more than three times that of ordinary ball mills, and the service life can be extended by 8-10 years.
(3) Higher grinding efficiency: Compared with the same type of ball mill on the market, the grinding efficiency of this equipment has been increased by more than 50%. It is currently a highly efficient sphalerite grinding equipment on the market.
3. Flotation machine
The flotation machine is the core equipment in the zinc blende beneficiation process. It plays an irreplaceable role in improving the grade of zinc concentrate. The advantages of this equipment are mainly manifested in the following aspects:
(1) Safe and stable operation: The structure design is very compact, the technical parameter design is relatively reasonable, the failure rate is low, and the flotation process is very safe and stable.
(2) Lower operating cost: The equipment has a relatively large suction capacity, low energy consumption during operation, and low maintenance costs. Therefore, the total flotation cost is ultra-low, which can save at least 10% for the concentrator every year. A cost investment of about 10,000 yuan.
(3) High degree of automation: The equipment is equipped with a control system that combines automatic control, electric control and manual control. The degree of automation is greatly improved, and the adjustment and control are simpler and easier.
(4) The price is economical: our company independently undertakes all aspects of the research, development, production and sales of the flotation machine, and the expected profit is extremely low. Therefore, our company’s price positioning for the flotation machine is extremely low.
Since the sphalerite slurry after flotation contains a certain amount of water, it needs to be dried by a dryer. Our dryer not only has the structure of light weight, high degree of automation, simple operation and easy maintenance, etc. Advantages, at the same time, it has high drying efficiency, high output, flexible adaptability and other performance advantages, and it occupies an ultra-high share in the market.
Sphalerite beneficiation process
First, the mined sphalerite ore is crushed into particles of a certain size by a jaw crusher and then sent to a ball mill for grinding treatment. The ground sphalerite is classified by a spiral classifier to classify qualified sphalerite The mineral material is sent to the flotation machine for flotation processing. At this time, the corresponding flotation agent is added, and the flotation concentrate is sent to the finished product silo.
