Aqueous two-phase system (ATPS) extraction combined with a natural deep eutectic solvent
(NADES) is an environmentally friendly separation process. In this work, ATPSs were …

The growing demand for nickel increases the interest in its extraction from secondary
sources, such as mine flotation tailings. This paper proposes the use of activated carbon as …

Recently, cyanide leaching has been progressively inhibited by environmental pollution and
long processes. In this study, the effect of leaching conditions on the extraction of gold was …

Naphthalene sulphonate was used as a blanking agent to treat a gold ore with an 87% preg-
robbing index with the aim of improving the gold recovery during carbon-in-leach (CIL). The …

Low-concentration gold recovery from thiosulfate solutions (Au (S 2 O 3) 2 3–) was vital for
the application of thiosulfate leaching instead of traditional cyanide leaching in gold …

This paper describes the chlorination roasting-water leaching process for the volatilization
separation of gold, zinc and simultaneous vanadium recovery from carbonaceous gold ore …

The serious hazards posed by inhalable coal dust to the safety, air purity, and health of coal
miners can be effectively alleviated through the use of appropriate dust suppressants. The …

The sequential bio-treatment of refractory carbonaceous gold ore is a promising solution to
recover gold effectively by environmentally friendly technology, which includes bio-oxidation …

Several efforts are made to find various green alternatives for carbonaceous matter (CM)
degradation in carbonaceous gold ores. The deleterious effect of CM is observed during …

Two carbonaceous gold ores (ZAFB and ZAFV) underwent sequential biotreatment to
expose gold and minimize preg-robbing before cyanidation. These included comparable …
