RNC Minerals Begins Testwork to Produce Nickel and Cobalt

Apr 09, 2018· RNC believes that Dumont concentrate is highly suitable for this approach because of Dumont's industry leading nickel and cobalt content in concentrate and relatively low iron content In addition to demonstrating the process, quantities of nickel and cobalt salts will be made available for customer testing and analysis RNC's Roasting Approach.

Nickel ore processing

In the processing of nickel, typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder Water is added to create a pumpable slurry, which is treated with reagents during the flotation process in order to concentrate the nickel Smelting processes the concentrate further, creating nickel-rich matte, while impurities.

Long Harbour

Nickel concentrate from Voisey’s Bay are shipped to Long Harbour to be processed into finished nickel and associated copper and cobalt products In designing the LHPP, Vale sought to develop a new, more efficient process for processing Voisey’s Bay concentrate than traditional smelting and refining In advance of commercial plant.

Business

The new hydrometallurgical process that Vale developed will process the nickel concentrate directly to metal products without first having to smelt the concentrate The concentrate will be processed in a pressurized vessel where it will react with oxygen and sulphuric acid to produce an impure solution of nickel, cobalt and copper.

Copper-Nickel ores

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails Pentlandite and iron sulphides are depressed by raising the pH.

Nickel Concentrate

Nickel was first discovered by Alex Constedt in 1751 The nickel atom has a radius of 124 pm and a Van der Waals radius of 184 pm In its elemental form, nickel has a lustrous metallic silver appearance Nickel is a hard and ductile transition metal that is considered corrosion-resistant because of.

Process Development

Leaching of nickel-copper matte and recovery of platinum group metals Sherritt’s matte leach process uses sulphuric acid leaching in a combination of atmospheric and/or pressure leaching steps to quantitatively dissolve nickel and copper in nickel-copper matte and produce a high-grade platinum group metal (PGM) concentrate for refining.
