Abstract: As a result of the excessive consumption of nickel sulphide ore and the preponderance of laterite-nickel resource, such as shallow burial depth and low exploitation cost, the investigation of laterite-nickel ore utilization is more and more significant.The laterite-nickel ore genesis is very complex, and it is often formed via each other substitution of nickel, iron and magnesium in crystal lattice.Therefore, the nickel and cobalt is existed in mineral crystal lattice and it is impossible to be concentrated by using mineral processing.The pyrometallurgical and hydrometallurgical processes for treatment of high grade laterite-nickel ore have many advantages such as low production cost and low energy consumption.Therefore, an in-depth understanding of characteristics of laterite-nickel ore will aid to select a low cost and low pollution treatment technology, and it is a key step in successful utilization of laterite-nickel ore.
