____________________________________________________________________________________________1 Introduction In recent years, there is an increasing focus on the utilization of low-grade nickeliferous laterite ores, along with the growing demand for stainless steel and the declining of sulphide ores and high-grade nickeliferous laterite ores[1-4]. Nickeliferous laterite ore deposits are formed by the chemical weathering......
