Product Overview
Description
Product Description
After long-term experimentation and research, the R&D team has successfully developed a low-cost and highly active sustained-release alkaline material - Crabm product. This product can not only block the contact between acidic minerals and water to inhibit the production of acidic wastewater, but also release alkaline groups to neutralize the formed acidic water, ensuring that the discharged water is in the neutral range. Under the long-term action of the Crabm, a dense passivation film will form on the surface of the acidic ore, preventing further oxidation of pyrite.
1) Crabm-SF/N is suitable for the treatment of sulfur-containing gangue piles. It is used to evenly drill holes at a certain density, and the Crabm-SF/N material is grid sprayed on the surface and inside of the gangue piles. Under the action of water, the material gradually disperses evenly;
2) Crabm-SF is suitable for the old kiln water accumulation area in the goaf. Holes are drilled at different positions to inject Crabm-SF material into the accumulation area. Under the action of hydraulic power, it naturally homogenizes, neutralizes acidic water quality, and gradually passivates the surface of the ore;
3) Crabm-C is suitable for mining sections in goaf areas. Crabm-C material can be directly slurried and sprayed onto the mining section to prevent ore oxidation and form a passivation layer on the surface of the ore.

Conclusions from real applications
1. Analysis of experimental water quality
Clear and iconic characteristics of treatment technology and products for acidic mine contaminated water sources
》The treated water quality can maintain a neutral pH value for a long time.
》The treated water quality can maintain a stable low content of Fe and iron ions for a long time
》Maintain a low level of SO sulfate ion content in the treated water quality
2. Colony analysis of experimental water quality
Microscopic observation of the presence of microorganisms in the experimental group water clearly confirmed the presence of point like microbial colonies, indicating that the material did not cause significant damage to the ecological environment of water quality and still maintained a good biological environment.
3. SEM analysis of test materials
The morphology of the particle surface was observed and confirmed by electron microscopy to indicate the deposition of nano based small particles on the surface of the particles in the experimental group. In contrast, there was no similar deposition of small particles on the surface of the raw ore particles without product addition.
