Design And Operation Of The Hydrochem Flotation Column

Hydrochem Developments Ltd. has developed and put into full scale operation a novel type of vertical flotation column incorporating a multiplicity of mechanically agitated stages. Characteristics of this flotation column include a low height to diameter ratio, high upgrading factors and the possibility of modifying geometry and operation to specific flotation requirements. A commercial unit is currently handling up to 100 tpd rougher concentrate at Dickenson Mines Limited, Balmertown, Ontario. Design parameters and plant performance will be discussed.
