MINING AND PROCESSING : The mining methods differ with respect to the type of ore being mined. Since nickel is composed in two types of ores, both of them are mined differently. The sulfide ores are mined using underground mining methods though open-pit mining can also be done in early stages. The laterite ores are mined through applying earth

Processing Nickel Ores. One Mine''s Nickel Processing of Pyrrhoite, Chalcopyrite and Pentalandite Ores. The ore is crushed to -5 inches in primary cone crushers, then reduced to -1/2" in short head cone crushers. The ore is then ground to -100 mesh in ball mills. Using wet magnetic separators the magnetic ore is separated (pyrrhotite) and

2.EXTRACTION OF NICKEL • The extraction of nickel and ferronickel from laterite and sulfide ores • Laterite ores occur as saprolite, smectite and limonite layers because of their different compositions and mineralogy, they require different methods of extraction (Cu₈Ni₁₆Fe₁₀) • Saprolite , which has a relatively low iron content, is smelted. Limonite and smectite ores, which

The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

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
