Lateritic Nickel Ore Deposits Ore Deposits Technology

Lateritic Nickel Ore Deposits - Ore Deposits. Typical nickel laterite ore deposits are very large tonnage, low-grade deposits located close to the surface. They are typically in the range of 20 million tonnes and upwards (this being a contained resource of 200,000 tonnes of nickel at 1%) with some examples approaching a billion tonnes of material.

In this Example the lateritic nickel ore was supplied by the Hanna Mining Company and the higher pH range was used illustrating the differential flotation of the host rock minerals over the nickel. The ore was ground for 30 minutes using a ball charge at a density of 50 percent solids in the presence of 59 lbs. per ton of sodium silicate. Learn More

Bioleaching of Sukinda laterite using ultrasonics

Apr 01, 1995 Substrate Lateritic nickel ore obtained from Sukinda was ground to 105 ,um and was used for leaching. Elemental analysis of ore was carried out by atomic absorption spectrophotometry after acid digestion. 2.2. Microorganism The fungi strain A. niger, isolated earlier from lateritic nickel ore by enrichment culture using 2% potato dextrose ... Learn More

Lateritic nickel ore deposits and similar topics

Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. Wikipedia. Garnierite. General name for a green nickel ore which is found in pockets and veins within weathered and serpentinized ultramafic rocks. It forms by lateritic weathering of ultramafic rocks and occurs in many nickel laterite deposits in the world. Learn More

Laterite Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate ... Learn More

US4410498A Acid leaching of nickel from serpentinic

Sulphuric acid leaching has been used in the treatment of lateritic ores for the recovery of nickel and cobalt therefrom. However, in order to obtain good extraction from these ores, prolonged treatment using acid of high strength and also using high pressures and recycling steps have been necessary. In the improved method of the invention nickel and cobalt is solubilized from high-magnesia ... Learn More

Nickel Laterite Ore Deposits Weathered Serpentinites

Apr 01, 2013 Nickel laterite ores account for over 60% of global nickel supply. They are the product of intensive deep weathering of serpentinites under humid tropical conditions. Nickel is concentrated to over 1.0 wt% and is hosted in a variety of secondary oxides, hydrous Mg silicates and smectites. The formation, mineralogy and grade of the deposits are controlled by the interplay of lithology, tectonics, … Learn More
