  Pulp chemistry in sulphide mineral flotation - ScienceDirect

  1991111 · Pulp chemistry in sulphide mineral flotation. Variations in the oxidizing conditions of the pulp and their subsequent effects on flotation were examined for three types of natural sulphide ore, a complex pyrite ore, a sphalerite-galena ore and a chalcopyrite ore. Different gas mixtures ranging from pure nitrogen to pure oxygen were …

  Optimize flotation process of Mo–Bi sulfide ore for cleaner production ...

  202141 · This study aims to optimize the traditional flotation process of Mo–Bi sulfide ore by using the difference in natural floatability of minerals for cleaner production. Single-mineral flotation tests demonstrate that the natural floatability of the sulfide minerals investigated decreased in the following order: molybdenite > bismuthinite > pyrite.

  Redox potential control during flotation of a sulphide mineral ore

  2017815 · Redox potential (Eh) control can play a critical role during sulphide mineral flotation by influencing the reactions on the surface of the minerals and consequently the flotation behaviour. Such control is usually a combined function of dissolved oxygen and pH control but can also be achieved by using appropriate chemical modifiers.

  Gold Flotation - 911 Metallurgist

  2016713 · Gold Flotation Though the gold recovery methods previously discussed usually catch the coarser particles of sulphides in the ore and thus indirectly recover some of the gold associated with these and other heavy minerals, they are not primarily designed for sulphide recovery. Where a high sulphide recovery is demanded, flotation methods are …

  2020723 · Water chemistry is one of the most important parameters affecting flotation performance. Various types of ions can dissolve and accumulate in process water depending on ore mineralogy, reagent scheme, grinding medium and chemistry of mine site water. Sulfur-based ions (sulfate, thiosulfate, polythionate) are generally observed in flotation of …
