1. Introduction

Laterite ore is a major primary source of nickel and cobalt production along with sulfide ore. There are various processes that have been implemented for extracting nickel from laterite ore. Basically, those processing technologies use pyrometallurgy, hydrometallurgy or a combination of these routes dependent on the ore type, the availability of energy and some other specific factors [ 1 ] .
