The processing of laterite ores for the recovery of nickel and cobalt has increased as the reserves of exploitable sulphide ores have become depleted. The pressure acid leach process (PAL) has become the preferred option for the treatment of laterite ores. Difficulties associated with the poor settling characteristics of the pulp in the counter current decantation (CCD) circuit after pressure ...

Nickel Laterite deposits Flashcards | Quizlet

Why are nickel laterites a becoming cheaper alternative to nickel sulphide deposits? Due to their presence at the surface they can be mined in open pits (cheaper). Also the advancement of extraction techniques allows extraction of lower grade ores (High pressure leach techniques). Getting easier to beneficiate.

Nickel and cobalt values are enriched in the fines fractions of both the limonite and Saprolite ores, and the beneficiation process consists of rejecting the principally siliceous coarse fractions using conventional wet ore sizing equipment. Typical mass rejections of 6070% are achieved at a nominal nickel recovery of 6065%.

Laterite nickel ore is the most abundant nickel ore resource in the world. The nickel in laterite is in the state of a disseminated structure, and the effect of traditional mineral processing is quite poor. Only the large gangue minerals with a low nickel content and low rate of decay can be removed by wet or dry beneficiation. So far, no ...
