Nickel is an essential base metal in modern industries. About 60% of nickel is used to make stainless steel. In recent years, the market price of nickel metal and the volume of production of primary nickel and ore have been increasing. Therefore, the demand in laboratories for accurate and fast analysis to determine multiple metal elements in ores is growing.

At mining sites, laboratories are often required to perform high volumes of analyses, up to a few hundred samples per day. However, wet chemical analysis, the conventional analytical technique for multiple metal determinations, is difficult to perform this scale because the method is time-consuming and requires significant analytical skill.

This note demonstrates the improved method to determine multiple elements in nickel sulfide ores by the pressed powder method, which can cover from Run-Of-Mine to concentrate.
