Investigation of the flotation performance of nickel

The effects of configuration of the stirred tank and energy input on the flotation performance of nickel ores were systematically investigated in this paper. Flotation tests revealed Flotation of sulfide nickel ores is usually carried out at alkaline pH in order to separate pentlandite selectively from iron sulfides. Alkaline pulp depresses efficiently Effect of some process variables on flotability of sulfide nickel ores

Copper Nickel Flotation 911 Metallurgist

The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct With the vigorously growing demand of the steel industry, corrosion resistance alloys, clean energy industries, and a variety of engineered infrastructure or technology, high-grade nickel ores are being exhausted gradually in the world.

Production of Nickel Concentrate from Ground Sulfide Ore

This chapter explains the process of nickel concentration from ground sulfide ore, the starting material. This is necessary because mined nickel sulfide ores contain between 1% and 3% Ni only andNickel-copper sulfide ore deposits are found at the base of mafic and ultramafic bodies. All their host rocks, except the Sudbury Igneous Complex, are thought to be mantle derived melts. The Sudbury Igneous Complex is thought to be the product of complete melting of continental crust. In the case of mantle-derived magmas, a high degree of partial melting Formation of magmatic nickel-sulfide ore deposits and

This critical pH of sulfide flotation is different from the critical pH of the PZC for flotation of nonsulfide minerals. Figure 18. Flotation domain of Chalcopyrite is another major mineral for nickel sulfide ores that must be considered when choosing extractive processes. Major nickel sulfide deposits are found in Canada, Russia, SouthSimplified flow sheets of representative flotation plant operations are given to illustrate how these principles are applied for the commercial separation of sulphide minerals from their ores. Various novel techniques that take advantage of controlling the electrochemical and physical behavior of the flotation system are also presented.Principles and practice of sulphide mineral flotation

Nickel Sulfide an overview ScienceDirect Topics

Nickel sulfide minerals such as pentlandite can, in general, be separated from their gangue by flotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of variety of activators, depressants and dispersants. Since nickel sulfides contain other sulfides such as pyrrhotite, pentlandite and chalcopyrite, the enrichment of nickel The ore grades at Raglan and Voisey’s Bay are much higher than in the Sudbury region. However, since the production from Nickel Rim South Mine was brought online, Glencore’s flotation plant Strathcona started processing a higher grade ore with 1.57% Ni and 2.85% Cu (). 2.2 Challenges in Processing of Nickel-Copper Sulphide OresNi/Co–Cu Sulphide Ores, Key Contributors to Sustainability

Some factors that affect beneficiation of sulphide nickel–copper ores

The previous work of Kirjavainen and Heiskanen (2007) also reported that fine serpentine would cause problems in copper-nickel sulfide ores flotation processes, for example, by increasing the viscosity of the pulp. Dispersing agents were commonly used to decrease the coagulation of slurries.The direct hydrometallurgical processing of nickel sulfide concentrates and whole ores may be a remedy to these issues and hydrometallurgy offers several advantages over pyrometallurgy such as(PDF) The Direct Leaching of Nickel Sulfide Flotation
