Book Description
The depletion and expensive processing of nickel-rich sulphide deposits have posed a threat to the steel-making industry, where nickel is used as an alloy element. Processing of nickel sulphide ores by pyrometallurgy has also proven to be a challenge due to associated high energy requirements, strict environmental regulations on carbon emissions, expensive construction material and maintenance. Mining companies along with researchers are now challenged to develop new mining and metallurgical technologies which will be energy-efficient, cost-effective and environmentally friendly for processing lean nickel sulphide and low-grade laterite ores. Previously stockpiled low-grade nickel laterite ores are currently the potential alternative source of nickel for the steel-making industry. Hydrometallurgy has emerged as the most suitable processing method with low energy requirements and inexpensive construction materials. This study is aimed at finding an economic and environmentally friendly process suitable for atmospheric pressure leaching of nickel and cobalt from the Waterval Boven, Mpumalanga, low-grade nickel laterite ore using sulphuric acid (H2SO4)

Leaching of Low Grade Nickel Laterite Ore from Waterval Mine in Mpumalanga Through Electrochemical Process

Book Description
The depreciation of high grade sulphide ores has resulted to the use of low grade laterites to meet the global nickel demand. Available low grade laterite ore reserves in South Africa are underutilised. Suitable metallurgical process for recovery of nickel from these reserves is not yet implemented because the mineralogy is not well understood. Hence, in this research the mineralogy and recovery of nickel from low grade laterites was studied through electrochemical process. The research shows that it is feasible to selectively recover nickel from the low grade laterite ore using electrochemical leaching method. It is recommended that optimization of the electrochemical cell design be looked into to evaluate the possibility of scaling up for industry application.
