Flotation Machines Mineral Processing Metallurgy

5/6/2018· It is usual to prepare the pulp for flotation by adding the reagents to the grinding circuit or in a conditioning tank ahead of the flotation section, but soluble frothers such as pine oil and quick acting promoters such as the xanthates can be added at the head of the machine if desired, since the air lift provides enough agitation to emulsify and distribute them throughout the pulp. It is not as a rule advisable to introduce reagents into the air lift

Flotation level measurement techniques explained April

Level measurement of a flotation cell is not as straightforward as it first sounds because we actually measure the depth of the froth. Of interest in a flotation cell is how deep the froth is above the slurry, as this determines the grade of the resulting concentrate. The typical range for a froth depth is 600 mm from the top of the flotation cell, the launder, down to the slurry interface
