An Investigation of Millerite (beta-NiS) Flotation Behaviour in Alkaline Solutions in Cu-Ni Sulphide Mineral Flotation Separation
DownloadFall 2021
In the Sudbury Basin nickel deposit, the presence of a less common nickel sulphide mineral – millerite (beta-NiS) has a substantial impact on the Cu/Ni flotation separation efficiency. In this study, the flotation chemistry of millerite in alkaline solutions was investigated with pure minerals...
