Processing of oxidized nickel ores with

A method for processing nickel ores with ammonium chloride is considered. The results of thermodynamic calculations for the reactions of the oxide components of nickel ore with ammonium chloride are given. Thermogravimetric and kinetic investigations were performed. The technological sequence of the separation of oxidized nickel ores into individual oxides was developed.

Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

June 2018 Loss Prevention Liquefaction of Mineral Ores and

Ores and Mineral Concentrates June 2018 Introduction Solid bulk cargoes such as unprocessed mineral ores and refined mineral concentrates may appear to be in a relatively dry granular state when loaded, however, they may still contain sufficient moisture to become fluid under the stimulus of the compaction and vibration that occurs during a voyage. The resulting cargo shift can be sufficient

Microwave Treatment of Ultramafic Nickel Ores: Heating

responsive minerals in ultramafic nickel ores should also allow the temperatures required for serpentine dehydroxylation (600–700 C [21]) to be achieved during microwave treatment. The objective of this paper is to explore the microwave heating of ultramafic nickel ores and effects on the mineralogy, ore grindability, specific surface area and pentlandite liberation. The results are

Importance of Microscopic Studies in Mineral Dressing

Al and Mg are present in the chromite mineral itself or as separate gangue. Ore dressing will be of help only in the latter case. An ore from Byrapur Chromite Mines, Mysore, gave on analysis, a Cr/Fe ratio of 1.41. Under microscope no iron-bearing mineral other than chromite was noticed and hence the entire iron content was attributed to the com-

Copper-Nickel ores - Danafloat

Copper-Nickel ores. Pentlandite ((Ni,Fe)S) is the most important nickel sulphide mineral and is often associated with nickel-containing pyrrhotite and chalcopyrite. Gangue minerals can include talc and other troublesome silicates which must be dispersed and/or depressed. Recovery and separation entails floating all three sulphide minerals into a bulk flotation concentrate at natural pH or at

ESG and Nickel - Benchmark Mineral Intelligence

The benefit of treating a laterite ore pyrometallurgically is that you utilise a greater percentage of the resource as the iron and nickel become a product, by way of example for 1,000,000 tonnes of ore mined, you might make 300,000 tonnes of product with a nickel grade of 6-10%. The remaining residue is usually a dry glass type material that is inert and can be used for earthworks or just

Mineralogy and crystal chemistry of a low grade
