saprolite nickel ore grade:

Our Business — Nickel Asia Corporation

High-grade saprolite ore has a nickel content of about 1.7% while mid-grade saprolite ore has a nickel content of between 1.3 to 1.6%. Most of our high-grade saprolite ore were sold to Pacific Metals Co., Ltd. (PAMCO), who use the material as feed for its ferronickel smelter. Our mid-grade saprolite ore were sold to Japanese and Chinese clients.

Saprolite - Wikipedia

Saprolite (from Greek σαπρος = putrid + λιθος = rock) is a chemically weathered rock (literally, it means "rotten rock"). More intense weathering results in a continuous transition from saprolite to laterite.. Saprolites form in the lower zones of soil horizons and represent deep weathering of the bedrock surface. In lateritic regoliths – regoliths are the loose layer of rocks ...
