the beneficiation process of nickel ore,copper-nickel

Sep 24, 2020 The flotation of copper-nickel ore has the following four basic processes. 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 concentrate with low nickel content can be directly obtained

The present study focused on the re-processing of copper and nickel from mine tailings. In this work, recovery of copper and nickel from mine tailing by combined process of flotation and high pressure oxidative leaching were considered. In the first stage, effects of flotation parameters including collector type, collector dosage, and pH and pulp density were examined

Jan 06, 2016 Nickel ore dispersion before flotation using different reagents was investigated on a bench scale to improve metallurgical recovery and selectivity. The nickel ore had a content of 0.8 pct nickel and 14.5 pct MgO. A positive linear correlation between MgO and Ni was found. Carboxy methyl cellulose, both pure and combined with Na2CO3, was the best dispersant used
