Zinc Flotation Process

During flotation of Galena (lead) and sphalerite (zinc), why do we have to depress sphalerite first to effectively separate them?

The zinc tailings pass over a Wilfley Table which gives the operator a constant, visual picture of the efficiency of the zinc flotation machine, and also recovers additional zinc values. Zinc concentrates are fed to a Wilfley Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a Thickener.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Flotation separation and recovery of lead and zinc concentrates from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved quite effectively. Silver often provides highly significant economic value, if not the greatest value, with the silver most often associated with the galena mineralization which is fortuitous …

Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz.

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.

In spite of the fact that the basic treatment process is sequential lead–zinc flotation, in a number of operating plants several alternatives are used.

Most zinc is used in the galvanizing steel process. Other uses include the automotive, construction, electrical, and machinery industries. Zinc compounds include agricultural chemicals, paints, pharmaceuticals, and rubber.

Zinc Sulfate Centrifugal Flotation. Fill a 15 ml centrifuge tube with ZnSO 4 solution (1.18 specific gravity) and pour into a glass dish. Using a tongue depressor, push the feces (2 to 3 grams, a piece the size of a grape) through the strainer into the ZnSO 4 solution in the dish. Using a funnel, pour the ZnSO 4-fecal mixture back into the centrifuge tube.

Zinc. Zinc is often found in nature together with lead in sulfide ores. The metals are separated during refining. As zinc is resistant to corrosion and easy to apply, much of it is used to protect iron and steel-based products. Uses of zinc. Zinc is used as coating to protect iron and steel from corroding in the atmosphere, water and soil.
