Nickel mining with the CNA Pentos

Nickel laterite in the Sorowako and Petea area of South Sulawesi, Indonesia, is classified into one of two main types, depending on the bedrock and silica-to-magnesia ratio in the mineralization: West Block and East Block. The East Block mine is high-recovery, low-olivine (60­–65%)parent rock, whereas West Block is low-recovery, high-olivine (80–90%)parent rock. Petea is a mainly lateritic landform with below-average nickel content.
