The primary ore of the mining plant is a polymetallic ore. In addition to high content of useful minerals, the ore also contains a large amount of impurities such as clay and quartz. The existence of these impurities makes ore separation more difficult and tailings treatment difficult. In addition, the mine's wastewater contains a large amount of suspended solids and heavy metal ions, seriously affecting the surrounding environment.

In response to the above problems, a PAC solution is adopted:

Ore separation: Add PAC to the grinding process to improve the flotation effect of useful minerals and reduce the impact of impurities, thereby increasing the recovery rate of ore dressing.

Tailings treatment: Combine PAC with other agents to chemically consolidate tailings, reduce the footprint of tailings ponds, and reduce environmental risks.

Wastewater treatment: PAC is applied to the wastewater treatment system, and the suspended solids and heavy metal ions in the wastewater are removed through the flocculation of PAC, so that the wastewater can be discharged up to the standard.

After implementing the PAC solution, the mining plant achieved the following results:

Improve mineral processing recovery rate: By using PAC, the flotation effect of useful minerals has been significantly improved, and the mineral processing recovery rate has increased by more than 10%.

Reduce the risk of tailings: Through the joint action of PAC and other agents, the chemical consolidation effect of tailings is obvious, and the footprint of tailings ponds is greatly reduced, which effectively reduces environmental risks.

Standard discharge of wastewater: After using PAC, the treatment efficiency of the wastewater treatment system is significantly improved, suspended solids and heavy metal ions in the wastewater are effectively removed, and the discharge of wastewater meets the standard.

By applying PAC in the mining process, the mining plant has achieved remarkable results in ore separation, tailings treatment and wastewater treatment. The application of PAC not only improves the recovery rate of ore dressing, reduces the risk of tailings, but also realizes the discharge of waste water up to the standard, creating good economic and environmental benefits for the mining plant. Therefore, it is recommended to promote the application of PAC technology in mining plants in Inner Mongolia and other regions to promote the sustainable development of mineral resources and environmental protection.
