Alkylated phosphorothionate and cationic collectors: BASFRecent Research Landscape

Silicate impurities in iron ore reduce smelting efficiency and increase processing costs. This lever utilizes specific hydroformylation by-products and iron chelators to selectively separate gangue minerals from high-grade ore.

What technical problems is BASF addressing in Alkylated phosphorothionate and cationic collectors?

Low mineral recovery selectivity

(23)evidences

Ineffective removal of silicate impurities from iron ore during alkaline flotation. Improving selectivity reduces gangue content in the final mineral concentrate.

Fine particle recovery inefficiency

(3)evidences

Small mineral particles lack sufficient mass for traditional separation and often remain suspended or lost in tailings. Agglomeration and carrier-assisted separation overcome the surface area to mass ratio limitations that prevent effective capture.
