The use of Na-CMC in mineral processing: as a filter aid and inhibitor

In the mining process, especially in flotation and drilling processes, the quality and filtration efficiency of the filtrate are crucial. Na-CMC is an ideal filtration aid due to its excellent thickening and water retention properties.

Na-CMC can increase the viscosity of the slurry, thereby improving the settling speed of solid particles and the quality of filter cake formation. This helps separate solids and liquids more efficiently, reducing filtration time.

Using Na-CMC can significantly reduce the suspended solids content in the filtrate, resulting in a clearer filtrate. This is particularly important in mining operations where high purity filtrate is required, such as those used in electrolytic refining.

In the ore flotation process, selectively inhibiting the surface activity of certain minerals is an important step to successfully separate valuable minerals. Na-CMC has the following advantages as an inhibitor:

1. Na-CMC can selectively adsorb on the surface of certain minerals, such as silicates and oxide minerals, reducing the hydrophobicity of their surfaces, thereby inhibiting the floating of these minerals during the flotation process.

2. By suppressing unwanted minerals, Na-CMC can improve the enrichment efficiency and concentrate quality of target minerals (such as copper, lead, etc.). This helps reduce impurities in subsequent smelting processes and improves metal recovery.

3. Compared with other inhibitors, Na-CMC is an environmentally friendly and safe polymer compound that can effectively reduce the amount of chemical reagents required in the flotation process, reducing production costs and environmental pollution.

In actual mining operations, through the rational use of Na-CMC, mining companies can optimize their processes, improve resource utilization, and reduce environmental impact.
