The mining industry faces significant challenges related to water management and tailings disposal. Efficient separation of solids from liquids and the recovery of process water are crucial for both environmental compliance and economic viability. Polyacrylamide (PAM) has emerged as a vital chemical additive, significantly improving the efficiency of these processes, particularly in tailings dewatering and water recovery. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier of high-performance PAM, offers solutions that address these critical needs in the mining sector.

PAM in Tailings Management: Dewatering and Consolidation

Tailings, the waste material left over after the process of separating the valuable fraction from the uneconomic fraction of an ore, often exist as fine slurries. Dewatering these tailings is essential to reduce their volume, lower transportation costs, and promote faster consolidation, allowing for more efficient land use and reclamation.

High molecular weight anionic or non-ionic PAM is commonly used as a flocculant in tailings management. When added to the tailings slurry, PAM molecules bridge the fine mineral particles, forming larger, denser flocs. These flocs settle more rapidly, facilitating the separation of water. This process is often employed in thickeners and clarifiers to increase solids capture and reduce the volume of water requiring further treatment or disposal. The efficiency of dewatering is directly related to the molecular weight and charge density of the PAM used, as well as the mineralogy of the tailings.

For mining operations, sourcing consistent and high-quality PAM is paramount. Our range of PAM products is engineered to provide superior flocculation and dewatering performance, helping to improve water recovery rates and reduce the environmental footprint associated with tailings disposal.

Water Recovery in Mining Operations

Water scarcity is a significant concern in many mining regions. Efficient water recovery from tailings streams and other process water allows mines to reuse water, reducing their reliance on fresh water sources and minimizing discharge volumes. PAM plays a critical role in this by:

  • Clarifying Process Water: PAM aids in removing suspended solids from process water, making it suitable for reuse in various stages of mining operations, such as dust suppression or slurry preparation.
  • Improving Thickener Efficiency: By promoting faster settling of solids in thickeners, PAM increases the throughput of these units and enhances the clarity of the overflow water, which can often be recycled.

The selection of the appropriate PAM type and grade is crucial for maximizing water recovery and ensuring compliance with discharge regulations. Factors such as the pH of the process water, the type of minerals present, and the concentration of dissolved solids all influence PAM performance.
