Aside from antimony ore grade, this decision falls on the mineral's association with other metals, for e.g. lead, copper, iron, mercury, arsenic, silver and gold, as well as other parameters such as ore matrix and type (sulfide or oxide). ... Many simple and complex low-grade antimony sulfide ores can be processed through …
1. Introduction. At present, more than 35% of China's gold resources (with a total amount of more than 1,000 tons) are difficult to be exploited and smelted, and about 700 tons of gold ores with high arsenic, antimony or sulfur are difficult to be directly cyanide leached (Lei et al., 2016).However, as the gradual depletion of easy-to-treat gold ore …

INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure …

Evidence for the occurrence of antimony can be traced back to antiquity. 1 The name comes from the Greek, anti and monos, meaning 'metal not found alone'. 2 Indeed, antimony is usually found as the sulfide ore, stibnite, Sb 2 S 3, the black form of which was used by ancient Egyptian women as a cosmetic for darkening their eyebrows …
