STAL Processing: An Effective Method for Nickel Ore Extraction
Roasting process is a water separation from nickel-ore. Leaching stage is a metal separation using sulfuric acid. From this stage, the main product is mixed-hydroxide precipitate (MHP) with 30% nickel concentration. And the last stage is MHP purification process using electrowinning method. In fact, Indonesia has a 9.4 billion ton that mostly low-content nickel under 1.7%. By implementing STAL

Nickel Ore and Metals Analysis
This article examines contemporary routine and umpire quality methods for the analysis of nickel ores, nickel metal and nickel alloys. Sample preparation and sampling are also discussed, but the emphasis is on sample preparation and analysis, since sampling is all too often done by people not part of the analytical laboratory.

Nickel beneficiation process,process design for beneficiation of nickel
Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The most important method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods.
