Silver Gold Recovery Flotation Process -

The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class ...

Advantages and Disadvantage of Froth Flotation

The froth flotation method is that the mineral selectively attaches to the air bubble by flotation reagent based on the physical and chemical properties of mineral surface. It is not difficult to see that the first two methods mainly rely on the nature of the ore itself, while the froth flotation method mainly relies on the added flotation reagents for separation based on the nature of the ore itself.

Flotation Froth - an overview ScienceDirect Topics

The use of froth in flotation is twofold. First, froth is used to convey the mineral-laden bubbles from the froth–pulp interface to the concentrate launder. Second, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp (Figure 13). The froth cleaning process can be improved by spraying (wash) water upon the surface or inside the upper layer of the froth. The spraying increases the volume of water draining through the froth
