• Flotation ore dressing Britannica

    Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

    Principle of operation. Before froth flotation can , the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains.This process is known as liberation.The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required.

    The beneficiation of fluorite ore is gravity separation and flotation process. The specificity of fluorite flotation: 1. Because industrial making hydrofluoric acid require calcium fluorite content>98% and silica <1%, fluorite flotation generally use 5-7 stages concentration; 2. When the PH of ore pulp is 8-11, the floatability is good. Another, increasing the temperature of ore pulp can
