Low grade nickel saprolites are not treated. The Caron process for nickel laterite treatment produces residues that still contain significant quantities of un-leached nickel and cobalt. The Starved Acid Leach Technology (SALT) was developed to recover nickel and cobalt from these lean resources. Relatively small amounts of acid are applied to ...

The bacterial leaching of flotation concentrate of copper-nickel sulfide ores (Jinchuan mine in China) containing chalcopyrite and pentlandite was studied using Thiobacillus ferrooxidans. About 75 percent of nickel in the concentrate was dissolved after 42 days of bacterial leaching, but the extraction of copper was only 14 percent. In order to enhance …

The fabric of the saprolite is related to the original lithic fabric, which is most obvious in the lower saprolite (Fig. 1).As the primary minerals weather, voids develop and secondary minerals are formed, which can cause the break-up of the lithic fabric in the upper saprolite (see also Stoops & Schaefer, 2010, this book).Saprolites on gneiss, …

Every year, more than 2.25 Mt of nickel are extracted from mines worldwide. SS accounts for two-thirds of all nickel demand worldwide (Fig. 5). Moreover, half of the yearly global nickel demand comes from China. Ten years ago, China's nickel usage accounted for less than 20% of world demand. India's nickel requirement is roughly 45,000 t,

High-iron limonite ore has a nickel content of less than 1.0% and an iron content of 48 to 50%. Low- grade limonite ore has a nickel content of 1.0 to 1.2% and an iron content of at least 30%. Our high-iron limonite ore were sold to Chinese customers who use the material as feed for blast furnaces for production of low-grade NPI.

In this work, we have applied the results of these tests to the flotation of a nickel ore that contains pentlandite, pyrrhotite, pyrite and talc. The outcome has been the development of a flowsheet (Senior et al., 1991 ) which offers the prospect of a selective separation of the pentlandite from the pyrrhotite and the talc. 2.

It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., …

In general, the type of bedrock influences the nature of the saprolite. Saprolites are commonly deep on quartz-rich lithologies such as granite, granitic gneiss, schists and sandstones, but they are shallow to nonexistent on quartz-free calcareous, basaltic and mafic lithologies. 3. General Micromorphological Features.
