In the western part of Turkey, there are low-grade lateritic nickel ores. They mainly occur as limonitic laterites with saprolite layers and, to a lesser extent, as serpentinic laterites. Extraction of nickel from these low-grade lateritic ores (those containing less than 2.0 wt% Nickel) is becoming more important because of the shortage of high-grade nickel sources. Also cobalt which is a precious metal is found in lateritic layers of nickel.The objective of this study is to recover nickel and cobalt from these ores under the optimum conditions by using hydrometallurgical methods.
