Nickel ore
Indonesian laterite ore falls into two main types with different chemistry and processing routes. The parameters below define what we match on; actual values are confirmed per cargo.
Lower-profile laterite with higher nickel and magnesium content and lower iron. The primary feed for rotary kiln–electric furnace (RKEF) smelters.
Upper-profile laterite with high iron and low magnesium content. Commonly processed by high-pressure acid leaching (HPAL).
Nickel ore
Laterite nickel forms as ultramafic rock weathers in tropical conditions. Iron-rich limonite accumulates near the surface; magnesium-rich saprolite lies beneath it, above the parent bedrock.
