Gold-bearing ore from a Russian deposit that contains 4.9 g of gold per ton of ore, 0.2% antimony, and 0.3% arsenic was subjected to concentration. The flow chart that was developed for recovering antimony while concentrating the gold-bearing ore (Fig. 1 ) includes collective flotation of the sulfide minerals and selective flotation to separate ...

Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …

Refractory gold ore generally refers to ore with less than 80% cyanide leaching rate. There are many reasons for refractory behavior: gold is locked within pyrite/arsenopyrite (Zhang et al., 2016b), carbon-containing substances exist and gold combines with arsenic, antimony and other characteristic elements (Xing et al., 2019). In …

The southern Tibet Au Sb metallogenic belt in the Himalayan orogen consists of more than 50 gold, gold–antimony and antimony lode deposits, and associated placer gold deposit.The deposits are hosted in a Mesozoic metamorphosed turbidite sequence of the Indian passive continental margin.The Zhemulang Au deposit, Mazhala Au Sb …

A free milling gold ore and a "synthetic" preg-robbing gold ore, which was prepared by adding activated carbon to the free milling gold ore, were also tested to confirm the validity of the method adopted. ... Process flow …

Preparation of Antimony Sulfide and Enrichment of Gold by Sulfuration–Volatilization from Electrodeposited Antimony. Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the….

The southern Tibet Au Sb metallogenic belt in the Himalayan orogen consists of more than 50 gold, gold–antimony and antimony lode deposits, and associated placer gold deposit. The deposits are hosted in a Mesozoic metamorphosed turbidite sequence of the Indian passive continental margin. The Zhemulang Au deposit, Mazhala Au Sb …

Orogenic antimony-gold deposits contribute significantly to the global antimony resource base. China's orogenic antimony-gold deposits are primarily in southern Tibet. Investigations indicate that antimony combines and migrates with sulfur hydroxides in ore-forming fluids. Previous research on fluid inclusions in orogenic …
