Directly use priority flotation or partial priority flotation process: When the copper content in the ore is much higher than the nickel content, this process can be used to select copper into a separate concentrate. The advantage of this process is that copper

The Effect of Oxidation on the Flotation Behaviour of

In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.

A Comparative Study of Kinetics of Flotation of a Copper

Copper-nickel ore from INCO mines, Sudbury, Ontario, Canada was used in the experiments. The approximate ore composition was pentlandite 4-5%, chalcopyrite 4-5% and pyrrhotite 30-35%. The ore was ground in a polyurethane lined rod mill with stainless steel charge to avoid any external iron getting into the flotation system.

The effect of sodium carbonate on the flotation performance of a nickel ore was studied and the mechanism investigated. The flotation results show that lizardite minerals in the ore interfere with the flotation of pentlandite,

Pentlandite oxidation in the flotation of a complex nickel

Jan 01, 2011 1. Introduction. Pentlandite flotation in Western Australia has historically been difficult due to a low nickel grade and large amounts of serpentine minerals (Senior and Thomas, 2005).The hypersaline water used in the flotation plants makes the traditional serpentine dispersants ineffective (Wellham et al., 1992).In the past 10 years, many studies have been conducted and nickel recovery

Enhanced methods for nickel recovery from low-grade ores

All nickel ores have relatively low nickel content, the classification is as follows: high-grade nickel ore has Ni content greater than 1.8%, middle-grade nickel ore has Ni content between 1.3-1.7%, low-grade nickel ore has Ni content between 0.6-1.2%. Nickel is continuously mined, even at these low percentages of ores, because it is in high

Flotation Reagents’ Types and Working Principles CNFREE

Flotation reagents refer to the agent that used in mineral flotation process, which can adjust the flotation behavior of minerals thus achieving a good effect of mineral separation.Currently using flotation reagents is the most flexible, effective, and convenient method of controlling flotation process.The commonly used flotation reagents can be mainly divided into three types according to

recovery and grade of PGMs from UG2 ore by flotation. Flotation is a process of separating minerals from one another: this technique depends primarily on the difference in the wettability of the particles. This concept is broad and researchers continuously carry out test works to find optimum conditions to improve both grade and recovery of PGMs.
