Saprolite Wikipedia

Saprolite is a chemically weathered rock. Saprolites form in the lower zones of soil profiles and represent deep weathering of the bedrock surface. In most outcrops its color comes from ferric compounds. Deeply weathered profiles are widespread on the continental landmasses between latitudes 35°N and 35°S. Conditions for the formation of deeply weathered regolith include a topographically moderate relief flat enough to prevent erosion and to allow leachingof the products of chemical weathering. A second conditi

Pre-concentration of nickel in laterite ores using

Sep 01, 2019 Nickel was upgraded in two samples of saprolite and the intermediate zones by gravity separation using the Falcon concentrator. The Ni grade increased by 17% and 36% for the saprolite and intermediate samples (i.e. ore S and I), respectively. The proportion of fine particles in the ores increases after gravity separation.

Processing of Nickel Laterite Ores on the Rise

Most laterite ore deposits are made up of both limonite (iron rich) and saprolite layers, with the thickness of each layer varying significantly across different deposits. Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, while saprolites are
