Mine Tailings Treatment

With the development of economy, the demand for mineral products increased significantly, the scale of mining development increased, resulting in the number of beneficiation tailings will continue to increase; coupled with the number of available metal ore grade is decreasing, in order to meet the growing mineral products Demand, the scale of mineral processing is increasing, so the number of beneficiation tailings will also be a substantial increase, and a large number of tailings, to the mining, the environment and the economy caused a lot of problems. So how to deal with tailings? What are the tailings treatment?

1, tailings storage. The amount of tailings for a plant is large and must be properly stored;

2, tailings water reuse. In order to reduce the consumption of fresh water and tailings water emissions, to reduce the tailings of the water pollution, tailings water reuse to pay attention.

3, tailings water purification. Drainage to the tailings of the plant, if the impurity content exceeds the national health standards, tailings water must be purified after the discharge.

Mine Tailings treatment system dedicated to the tailings of the mud separation, mud can be graded treatment to achieve the purpose of mud and water separation;

Set the mechanical and electrical control as one of the mine tail mud water treatment system;

Tailings Treatment System The surface coating is durable and ensures that the system is used in applications where wear and corrosion are large.

Mine Tailings treatment system characteristics

(1) low energy consumption, high dehydration rate, easy installation and use, easy maintenance;

(2) tailings centrifuge to achieve tailings slag dry speed manually adjustable, the most important thing is to automatically start the device automatically control the protection;

(3) tailings centrifuge without filter cloth, do not have to backwash water, can be applied to a variety of materials to choose the actual situation.

Tailings treatment system applications

Applicable to all kinds of tailings mud treatment, slime dehydration, washed quartz sand, construction mud dehydration, washing field sand field mud sludge treatment.

Tailings treatment system advantages

The general concentration of 18% -30% of the tailings slurry, after my company’s tailings treatment system after treatment, tailings sludge moisture content of 10% -30%, and even some coarse sand tailings can reach 10% Fully meet the tailings dry pile, the treated water is clear and transparent (optional flocculant) to achieve the standard of recycling.

 

Mine Tailings Treatment

Mine tailings treatment is based on the size of tailings, graded treatment, graded use, that is, the hydrocyclone graded coarse sand (about 40%) filling the underground goaf and tail sand filling filling column, efficient centrifugation Filter filter, the dry sand stacked in the vicinity of the plant on the hillside, and the cover soil.

In the sedimentation tank, sewage treatment tank for secondary sewage treatment of 70 ~ 80% of the tailings water back to the plant re-use. The invention uses the small overflow dam of the sedimentation tank and the sewage treatment tank instead of the traditional tailings dam.

Tailings are the least valuable part of the target component in the beneficiation operation and are no longer suitable for sorting under current economic conditions. With the socio-economic and sorting technology development, tailings in the useful components can also be further recycling. While the other components in the tailings are not completely useless waste, according to its nature and composition can be comprehensive utilization, to achieve non-waste emissions, which is the full use of resources and environmental protection common requirements.

Tailings are misplaced resources, and their harmfulness is caused by improper handling. The hazards of tailings are mainly reflected in the harmfulness of elements and the harm of solid waste. The harmfulness of the elements is the flotation agent ions and other ions in the tailings. With the flow of water and air into the surrounding environment, it causes serious environmental pollution The tailings are the main components of industrial solid waste, and the accumulation of tailings is caused by the accumulation of land, vegetation destruction, land degradation, desertification and dust pollution, water pollution and so on.

From the protection of the environment and the full use of resources from the point of view, people put forward tailings, no tail emissions and other requirements. Now the overall idea of ​​tailings comprehensive utilization is:
1. In the tailings comprehensive physical and chemical analysis, based on the re-election of the use of the value of the tailings re-election;
2. After the re-election after the tailings for simple processing As a building material or the use of tailings filled with mined areas;
3. The tailings for finishing, the production of high value-added building decoration materials; 4. Temporary can not use the tailings as ecological restoration materials for ecological restoration and reconstruction.
