Integrated solutions for mining and processing plants
Chemical Engineering Solutions company offers comprehensive solutions for mining companies for dewatering enriched products based on fast filter presses and thickeners.
Every modern mining and beneficiation enterprise faces the problem of environmental protection, since in the ore processing processes, a huge amount of water resources are used to remove solid tailings, the dewatering of which is necessary to obtain purified water and return it to the production cycle.
We offer an effective solution to this problem based on a complex filtration unit consisting of a fast filter press and a high-performance thickener.
Process diagram:
Several stages of pulp dewatering at mining and beneficiation enterprises can be distinguished.
These include thickening and filtration processes, which allow achieving a high degree of solid concentration in the suspension up to 85% by weight.
The initial flow with a low solids content enters the thickener, where the liquid is clarified and solid particles are concentrated under the action of mass forces.
After clarification, the water is returned to the production cycle, and the thickened flow with a solid mass content of up to 70% is pumped into the filtration unit, where the final stage of dehydration takes place on filter presses to produce a cake.
High speed filter-presses
High productivity of filter-presses is a key factor in the harsh conditions of the mining industry, where effective results are required using special high-tech equipment.
Chemical Engineering Solutions company designs and supplies rapid filter presses of the FPF 1500 and FPF2500 models for coal and mining industry.
Advantages:
- High productivity due to the expansion of the entire plate package
- Consistently low moisture content of the sludge (concentrate)
- Plate design for working with abrasive pulps
- 100% automation of the filtration process
- Measuring moisture and cake weight during the cycle
- Quick replacement of free-hanging napkins from the plates
- Shaking and washing of fabrics every cycle
Thickener
There are several stages of processing a mixture of water with gangue (pulp) in the mining and processing industry.
One of them is the thickening stage, the purpose of which is to obtain a highly concentrated suspension (or sediment) and clarified liquid as the final product.
During thickening, special equipment is used - thickeners, they are used to recirculate waste water or chemical reagents, increase the concentration of solids in tailings sent for storage, as well as control water consumption at various stages of the ore processing and beneficiation process.
Thickeners are an important link in the technology of mineral processing, used to increase the concentration of minerals and prepare for the subsequent filtration process. The high-performance thickener with a central hydraulic drive and an automatic rake mechanism lifting system is a modern equipment for separating solid and liquid phases by gravity sedimentation, designed taking into account all advanced technological solutions. The thickener consists of a round section tank with a support structure, a bridge with a central drive, a feed well, a rake system, a flocculant dosing system, a foam collection system, and pumps for removing thickened product. For outdoor placement, the thickener is also equipped with a full-size cover, thermal insulation, and a heated room above the central drive mechanism.
