Froth Flotation Process Used in the Lead Zinc Sulfide Ore,

The lead-zinc sulfide is often associated with a variety of valuable components, such as lead, zinc, copper, sulfur and other useful minerals, whose floatability is obviously different, which determines the different froth flotation process of lead and zinc sulfide ores.

The identification tests showed that the sample is a mixture of quartz, chalcopyrite,Froth flotation - Wikipedia,Before froth flotation can work, 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. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes a…

Lead Zinc Sulfide Separation by Sequential Flotation

In the majority of the zinc operations, sphalerite (ZnS) is associated with galena and often sulfides of iron and copper. It is therefore essential to arrange the flowsheet not only for recovery of the valuable minerals, but also to selectively separate them into products acceptable to the smelters for ultimate conversion into metal.

The main lead minerals are galena and lead alum. It applies the flotation sulphide ore - desilting - flotation oxidation ore processing technology according to the characteristic of lead ores. The final recovery rate of lead concentrate isFroth flotation - Wikipedia,As an example, sodium ethyl xanthate may be added as a collector in the selective flotation of galena (lead sulfide) to separate it from sphalerite (zinc sulfide). This slurry (more properly called the pulp) of hydrophobic particles and hydrophilic particles is then introduced to tanks known as flotation cells that are aerated to produce bubbles.
