MINING

Froth flotation Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Extraction of Gold

The electrolytic process was introduced in 1863 by Charles Watt at Sydney, started in 1878 by Wohlwill at Hamburg, and in 1902 by Tuttle at the Philadelphia Mint. In the goldchloride method the electrolyte is a solution of auric chloride containing free hydrochloric acid, the crude metal forming the anode, and pure sheet gold the hode.

Dewatering Problems Troubleshooting Guide

Dewatering Too Slow, Too Fast The most common problems related to dewatering involve slow or variable drainage and response to vacuum. Slow dewatering may involve quotslow initial drainagequot on the forming table, low solids after vacuum appli ion, low solids after wetpressing, or just a consequent lower operating speed of the paper machine.
