  Oxidative Dissolution of Low-Grade Ni-Cu Ore and Impact on Flotation …

  2022113 · This paper investigated the effect of mineral surface oxidation on the floatability of Kevitsa low-grade Ni-Cu ore. Physicochemical measurements, ethylene diamine tetra acetic acid (EDTA) extraction, and oxygen uptake experiments were carried out with slurry and recycled process water samples obtained from the Kevitsa Cu-Ni …

  A Review on the Application of Starch as Depressant in Iron Ore Flotation

  2020112 · The present paper attempts to highlight different facets of starch as an iron ore depressant. It reviews the important research papers that discuss the origin and chemistry of starch, starch-iron oxide interaction mechanism, and the application of different types of starches and their alternatives in iron ore flotation.

  Investigating the Mineralogy of an Oxidised South …

  2022731 · Little work has been done to quantitatively relate the surface oxidation to flotation performance which makes it inherently difficult for processing plants to optimise flotation conditions for oxidised ores. There is mineralogical contrast which has important implications for potential processing.

  The selective flotation of pentlandite from a nickel ore

  199561 · Abstract. Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject pyrrhotite. Concentrates have therefore been of moderate grade containing as much pyrrhotite as …

  Potential Use of Oxygen Depleted Air In Nickel Sulphide …

  2018820 · The first flotation stage concentrates mainly copper minerals. The copper middling is re-floated to obtain nickel concentrate. During the industrial process of copper-nickel ore, it was observed that significant amount of nickel sulphides was lost to the tailings during the nickel flotation.
