The acid pressure leach process for the treatment of low magnesium lateritic ore has been in operation at the Pedro Sotto Alba Plant in Moa, Holguin, Cuba since 1959. The plant was originally constructed by Moa Bay Mining Company, a subsidiary of Freeport Sulphur, and was taken over by the Cuban Government in 1960. The plant recommenced operations in 1961, under Cuban management, and after a series of problems encountered during start up were eliminated, production gradually increased and improvements were made to the recovery of nickel and cobalt.
