The mineral processing industry relies heavily on water for various operations, including crushing, grinding, and flotation. This extensive use of water generates large volumes of wastewater containing fine mineral particles, clays, and residual processing chemicals. Effective treatment of this wastewater is essential for environmental protection and operational efficiency. NINGBO INNO PHARMCHEM CO.,LTD. highlights the significant contribution of Anionic Polyacrylamide (APAM) as a key chemical auxiliary in mineral processing water treatment.

In mineral processing plants, the separation of valuable minerals often involves processes that create a high concentration of fine suspended solids in the process water. These fine particles, if not removed, can interfere with subsequent processing steps, lead to losses of valuable material, and cause environmental issues if discharged untreated. APAM is widely used as a flocculant and settling aid to aggregate these fine mineral particles, facilitating their removal from the water stream.

The mechanism of action for APAM in mineral processing is its ability to adsorb onto the surface of these fine mineral particles. The polymer's anionic charge can neutralize the surface charges of the particles, which are often negatively charged due to surface chemistries or the presence of naturally occurring clays. This charge neutralization reduces the repulsive forces, allowing the particles to come into closer contact. The long polymer chains then act as bridges, physically linking multiple particles together to form larger, more robust flocs. These larger flocs settle much faster and more completely in thickeners or clarifiers compared to the individual fine particles.

The benefits of using APAM in mineral processing are substantial. Firstly, it significantly improves the efficiency of solid-liquid separation processes, leading to clearer supernatant water. This improved water clarity allows for a higher rate of water recovery and recycling within the plant, which is crucial for water conservation in often water-scarce mining regions. Reduced water consumption lowers operational costs and lessens the environmental footprint of mining operations. Secondly, the enhanced settling of fines can also help in recovering valuable fine-grained minerals that might otherwise be lost in the tailings stream.
