Mining

Polyacrylamide (PAM) is mainly used as a flocculant and sedimentation aid in copper mining processing to improve the efficiency of solid-liquid separation. In the process of copper ore dressing and tailings treatment, the wastewater contains a large amount of mineral particles and suspended matter. PAM can cause these particles to aggregate quickly to form larger flocs, accelerate sedimentation and separation, and thus improve the clarity of the water. This helps to reduce the pollution of mining wastewater to the environment and improve the recycling rate of water resources. In addition, PAM can also improve the dehydration performance of tailings slurry, reduce water content, reduce the land occupation of tailings storage, and improve mine production efficiency. Through these effects, PAM effectively improves the treatment effect of mineral processing wastewater in copper mining processing, reduces environmental pressure, and promotes the recycling of resources.

Polyacrylamide (PAM) is mainly used for flocculation sedimentation, solid-liquid separation and tailings dehydration in gold mining. In the process of gold ore dressing and smelting, the wastewater contains a large amount of suspended particles, ore mud and metal impurities. PAM can promote these fine particles to aggregate into larger flocs, accelerate sedimentation, and improve the clarity of wastewater. This can not only improve the recycling rate of mineral processing wastewater, but also reduce pollution to the environment. In addition, PAM can also be used for tailings dehydration treatment to help reduce the water content of mud, making tailings easier to store and handle, thereby reducing land occupation and subsequent processing costs.

Polyacrylamide (PAM) is mainly used as a flocculant and thickener in aluminum ore mining to improve solid-liquid separation and sedimentation efficiency. In the process of aluminum ore beneficiation and red mud treatment, PAM can cause the fine mineral particles suspended in the wastewater to aggregate into larger flocs, accelerate their sedimentation and separation, and significantly improve the clarity of the wastewater. This process not only improves the recycling rate of water resources, but also effectively reduces the content of suspended solids in the wastewater and reduces the risk of environmental pollution. In addition, PAM helps to reduce the moisture content of the mud in the dehydration treatment of red mud, making the tailings easier to handle and store, reducing the land area and environmental burden.

Polyacrylamide (PAM) is mainly used for flocculation sedimentation, solid-liquid separation and tailings dehydration in iron ore mining. In the iron ore beneficiation process, the slurry wastewater contains a large number of fine mineral particles and suspended matter. PAM can cause these particles to aggregate into larger flocs, accelerate sedimentation, and improve the clarity of wastewater, thereby increasing the recycling rate of water resources. In addition, PAM can also be used for tailings dehydration treatment to help reduce the water content of tailings slurry, making it easier to store and transport, reducing land occupation and environmental pressure. At the same time, PAM can also optimize the iron ore beneficiation process, improve the concentrate recovery rate, and reduce the waste of mineral resources.

The main roles of polyacrylamide (PAM) in phosphate mining industry treatment include slurry thickening, tailings dewatering, wastewater treatment, and in phosphogypsum stockpile management, PAM can be used to enhance the solidification effect of the stockpile, prevent dust pollution, and improve the stability of the stockpile. By optimizing the solid-liquid separation and wastewater treatment process, it reduces resource waste and environmental pollution, providing important support for the green production of the phosphate mining industry. In addition, PAM can be used for tailings slurry dewatering treatment to reduce the water content of the slurry, making the tailings easier to stockpile and transport, thus reducing land occupation and environmental protection pressure. At the same time, PAM can also optimize the phosphorus ore beneficiation process, improve concentrate recovery and reduce resource waste.

Lead-zinc mines need to discharge a large amount of wastewater in the development of these wastewater, these wastewater quality is complex, high content of suspended solids, easy to cause damage to the environment, if you do not treat these wastewater in a timely manner, it will not only cause a waste of water resources, but also the environment around the vein of the mine will cause serious damage. Therefore, polyacrylamide can be used to purify and recover the wastewater from lead and zinc mines. Polyacrylamide can improve the flotation process, increase the recovery rate of concentrate and reduce the waste of mineral resources. In tailings treatment, PAM can reduce the water content of tailings slurry, make it easier to stockpile and transport, reduce the floor space and subsequent treatment costs.

Polyacrylamide (PAM) is mainly used for flocculation and settlement, solid-liquid separation and coal slurry water recovery in coal washing mining treatment. In the process of coal washing, a large amount of coal sludge and suspended particles are mixed into the wastewater, PAM can make fine coal particles and impurities quickly gather into larger flocs through strong flocculation, accelerate the settlement and improve the degree of clarification, which can help to recover the usable coal dust and reduce the waste of resources. In addition, PAM can enhance the dewatering efficiency of the thickening pond and filter press equipment, reduce the water content of coal slurry, make the filter cake easier to store and transport, and reduce the pressure of tailings stockpiling.

Polyacrylamide (PAM) is mainly used for flocculation and sedimentation, solid-liquid separation and tailings dewatering in fluorite mining processing. In fluorite beneficiation process, the slurry wastewater contains a large number of fine particles and suspended matter, PAM through flocculation to promote the rapid aggregation of these particles to form larger flocs, accelerate the settlement, improve wastewater clarification, reduce pollutant emissions. At the same time, PAM can optimize the flotation process, improve the recovery rate of fluorite concentrate and reduce the waste of resources. In the tailings dewatering process, PAM can reduce the water content of the tailings slurry, making the tailings easier to stockpile and transport, reducing the land occupation and environmental protection pressure.

The role of polyacrylamide (PAM) in manganese ore treatment is mainly reflected in slurry thickening, tailings dewatering, flotation auxiliary and wastewater treatment. Through its strong flocculation performance, PAM can effectively promote the fine particles in the slurry to gather into larger flocs, accelerate the settlement, improve the processing efficiency of the concentration pool, and reduce the time of slurry concentration. In addition, PAM can remove suspended matter, mineral particles and pollutants from wastewater in wastewater treatment, reduce the chemical oxygen demand (COD) and suspended solids (SS) of wastewater, ensure that the wastewater meets the environmental protection emission standards, and support the recycling of water resources.

Selection of polyacrylamide products as mining and metallurgical production coagulant aid, flocculant, dewatering agent, widely used in mining, mining, mining and metallurgical wastewater treatment, sludge dewatering treatment and other processes. At present, it has been successfully applied to iron ore, copper, gold and silver, molybdenum, vanadium and uranium mines and other industries in the field of mining and metallurgy, including coal, copper, gold, aluminum ore beneficiation; magnesium oxide, zinc, iron and steel, aluminum smelting wastewater treatment; part of the non-ferrous metal wet smelting and extraction of rare earth elements also play an important role in the process. In the beneficiation process, the slurry wastewater contains a large number of suspended particles and mineral impurities, PAM can promote the rapid aggregation of fine particles, accelerate the settlement, improve wastewater clarification, and reduce pollution emissions. At the same time, PAM can also optimize the flotation process and improve the recovery rate of mineral resources.
