Abstract Scope |
South Africa's economy is built on gold mining, the sector is an important foreign exchange earner, with gold accounting for more than one-third of exports. But due to decrease in high grade gold ores, the need therefore arises to investigate ground-breaking approaches for sustainable pretreatment of complex gold ores (CGO). Despite CGOs mineral composition (MC) assisting in figuring out their responsiveness to conventional treatment processes, the challenge of low degree of liberation remains. Hence, this paper presented a revised insight into pre-treatment methods for enhanced liberation and recovery of gold from CGO in South Africa. This aim was achieved by reviewing publications on the different pretreatment methods. It was concluded that it is important to develop cost-effective pretreatment method or combination of methods depending on MC of CGO for low cost and higher gold recovery rates in order to guarantee a sustainable gold industry in South Africa. |
