We produce two types of nickel ore, namely saprolite ore and limonite ore. Our saprolite ore comes in two types: high-grade and mid-grade, while our limonite ore are high-iron and low-grade. Most of our high-grade saprolite ore are sold to Pacific Metals Co., Ltd. (PAMCO), who use the material as feed for its ferronickel smelter.

Based on the data obtained within this work, we can conclude that the leaching of nickel from native ore with a solution of sulfuric acid does not lead to its higher recovery. To intensify the process of converting nickel into solution, it is necessary to apply intermediate operations, including low-temperature sulfation, drying, and roasting.
