The major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs. Also, it has been reported that the cost of installing a column flotation circuit is approximately 25–40% less than an equivalent mechanical flotation circuit (Murdock et al., 1991).

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 gold-chloride method the electrolyte is a solution of auric chloride containing free hydrochloric acid, the crude metal forming the anode, and pure sheet gold the cathode.

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 "slow initial drainage" on the forming table, low solids after vacuum application, low solids after wet-pressing, or just a consequent lower operating speed of the paper machine.
