What is the difference between limonite and saprolite?

The limonite and saprolite ore fractions can generally be distinguished by their lithologies; the limonite fraction being highly enriched in iron due to very strong leaching of …

Exploration and mining of lateritic gold deposits (Part I): Ore

In saprolite deposits, gold primarily exists as residual primary material, with some secondary gold and minimal dispersion. Under specific arid conditions characterized by …

DESCRIPTIVE MODEL OF LATERITE-SAPROLITE Au

THE DNi PROCESS™

The DNi Ni Process™ is a unique technology which can process the full laterite ore profile (limonite, saprolite, and transition zone) with nitric acid, and which extracts all the metals contained in the feed. Boasting a 99% nitric acid …

Why Megascopic Analysis Falls Short in Classifying Limonite, …

In lateritic nickel exploration, the differentiation between limonite, saprolite, and rocky saprolite is essential for resource estimation, metallurgical planning, and mine scheduling.

Limonite

In the Dahlonega gold belt in Lumpkin County, Georgia gold was mined from limonite rich lateritic or saprolite soil. The gold of the primary veins was concentrated into the limonites of the …
