The new rules also state that permits for the export of un-beneficiated lithium will not be granted unless the exporter operates an Approved Processing Plant (APP) or has obtained a permit to operate an APP that will be completed and fully operational within two years of the export permit's issuance. The permit must also be granted with the prior …

Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were low …

In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation …

Problems related to the effective processing of refractory gold ores containing carbon and arsenic are discussed. In the search for technologies for the extraction of gold from such ores, including those obtained from the Sayak-4 gold deposit, pyrometallurgical processing represents a possible direction. The results of an …

A Buhera-based Lithium mining company has stated its intentions to establish a world-class mineral processing plant in the country. In the company's presentation at the Chamber of Mines Annual Conference and Exhibition held in Victoria Falls last week, MAX MIND INVESTMENTS, the owners of the Sabi Star lithium project said the facility will …
