Nov 1, 2021In reality, to separate the required minerals from gangue, it is necessary to add many flotation reagents to enhance the hydrophilic/hydrophobic behaviors of different mineral surfaces. Therefore, the interaction between water molecules and the mineral surface is indispensable to the establishment of flotation theoretical systems.
2022-4-3 Flotation is an efficient method for separating minerals. The development of various flotation medicaments and the specific use in production practice, as well as the new development of flotation technology, have greatly improved the efficiency of flotation and expanded the scope of application of flotation; due to the increase in the types of flotation equipment, the Mineral ...
Greater mineral liberation. More permanent attachment of particles to bubbles. Coarse pulps on the other hand have in their favor the following arguments: Easier attachment of particles to bubbles. Increased flotation machine capacity. Decreased power consumption for flotation.
Flotation rate differences of the minerals as a function of pH under conditions of starvation collector usage also showed promise. Scheelite and fluorite float most rapidly with sodium oleate in slightly acidic (pH 4-7) solutions whereas calcite floats most rapidly near pH 10.
At a macro-level, efficiency in flotation can be driven using holistic engineering approaches. For example, Hatch offers two solutions — Mine to Mill and Grade Engineering — that aim to increase the overall efficiency of mineral processing operations, inclusive of flotation.
