laterite nickel process in cuba

PRESENT AND FUTURE OF NICKEL IN CUBA PROCUBA

Ruiz explained that the manufacturing factories today only extract nickel and cobalt, but since the beginning of nickel production in Cuba, more than 70 years ago, the industry’s tails are preserved, which contain 45 percent iron.

Treatment of Nickel-Cobalt Laterites

1. Nickel and cobalt can usually be solubilized from laterites using sulphuric acid at atmospheric pressure, just below boiling point. However, this generally requires a massive quantity of acid, which can render the process uneconomic. The main reason for this is that for limonitic ores in particular, the

Critical metals (REE, Sc, PGE) in Ni laterites from Cuba

Ni (± Co) laterite deposits account for about 60% of the current world's annual Ni production and host 60 to 70% of the world land-based Ni resources (Butt and Cluzel, 2013). In this context Cuba and the Dominican Republic host some of the world's most important Ni laterite deposits.
