Gold Flotation Process

The Basic Principle Flotation Process
In the flotation process of the major steps that must be done include:the process destruction of rock minerals, milling, flotation, drying and smelting : 

The process of destruction of rocks minerals and grinding
In this process of rock minerals that have been taken from the mine site and then destroyed by the machine to obtain a fine grain of sand to free metal-containing granules for further processing. In the destruction of mineral rocks of machine tools can use a stone crusher machine, so the minimum size of rock minerals can reach between 28 mesh

The Process of Flotation 
At this stage after a mineral ore that is refined inserted into the machine agitator tank which is usually also called a flotation cell to produce a pulp slurry concentrate.

In the process of this flotation Reagent Which In Use Is a form of lime, bubble and collectors. Froth forming a bubble that is stable and that float to the surface as a froth flotation cell. Collector reagents react with the surface of the precious metal sulfide mineral particles making the surface is water repellent. surface of the mineral-bound water molecule is released and will be changed to hydrophobic. Thus the collector end of the hydrophobic molecules will be bound hydrophobic molecules from the bubble, so the mineral ore can be adrift. Collector has a molecular structure similar to the detergent hydrophobic sulfide mineral grains are attached to the air bubbles that rise from the slurry zone into the froth that floats on the surface of cells.
 Valuable mineral-laden froth which resembles a metallic detergent foam, and foam concentrate that has been lifted from the drain into the upper lip and into the trough flotation machine is in use as a valuable mineral collection
The Process of Drying and Smelting: 
Valuable minerals that have been collected in the form of concentrates and mineral ore slurry 65% solids by weight in dry with the dryer until the water content there is only 9%. After all selasai dried it is ready for its mineral ore in the smelting process.
