Carrascal Nickel Corporation mines nickel ores from LATERITE, LIMONITE, SAPROLITE, which are originally formed from the deep weathering of bedrock in tropical and subtropical regions.
LATERITE is a soil type mineral commonly rusty-red rich in iron and aluminum. It is formed in hot and wet tropical areas.
LIMONITE is a common brown, black or yellow amorphous secondary mineral that consists of hydrated ferric oxides and is a source of iron.
SAPROLITE is a soft thoroughly decomposed and porous rock, often rich in clay, formed by the in-placed chemical weathering of igneous, metamorphic or sedimentary rocks.
