Experimental and DFT insights into the oxidation-induced deterioration of sodium butyl xanthate adsorption on pristine and hydroxylated (001) surfaces of carrollite (CuCo2S4)

Cobalt is a strategically important metal, but its efficient recovery from increasingly complex ores remains challenging. Flotation is widely used to recover cobalt sulfide minerals such as carrollite, with xanthates serving as common collectors. However, surface oxidation can im...

Selective lepidolite–quartz flotation using an environmentally benign collector dodecylbenzenesulfonate isopropanolamine activated by Ca2+

Efficient separation of quartz from low-grade lepidolite ores by flotation remains difficult because the two minerals share similar surface chemistry. In the present work, dodecylbenzenesulfonate isopropanolamine (LAS) was introduced as an environmentally benign collector, with C...
