Mineral Processing Additives

Using the right combination of collectors, dispersants, and frothers, mining and mineral processing companies can optimize the efficiency of the froth flotation process and increase the recovery of valuable minerals from their ores. The process involves adding certain chemicals or additives to the ore slurry to make the targeted minerals selectively attach to air bubbles and rise to the surface as a froth. Several types of chemicals are used in the froth flotation process, and three common additives include Xanthate, PNS Poly Naphthalene Sulfonate, and Tall Oils.

Modifiers such as Sodium Carbonate and Sodium Silicate are commonly used in froth flotation cells to improve the efficiency of the flotation process and increase the recovery of valuable minerals such as zinc, copper, molybdenum, pyrite, and galena.

In addition to their technical benefits, using Sodium Carbonate and Sodium Silicate can also provide economic benefits by increasing the recovery of valuable minerals and reducing the cost of reagents. Therefore, they are widely utilized in froth flotation cells in the mining industry.

Using Sodium Carbonate and Sodium Silicate as modifiers in froth flotation has been extensively studied and documented. For example, a study by Zhang et al. (2021) investigated the effect of Sodium Carbonate on the flotation of galena and found that it significantly improved the flotation performance by increasing the recovery of galena. Another study by Li et al. (2018) showed that adding Sodium Silicate improved the flotation performance of copper oxide minerals.
