In flotation machine processing, to be diligently observe the foam color, foam thickness and scrape the voice changes which is optional, good judgment for the control of a screening method. Nickel ore sorting process, roughing operations are mainly watching real heavy foam, the foam layer is thicker, more uniform bubble size is, most are not the first tank to tank, foam thickness, there is an obvious color changes; bubble blown foam whether the tank chirping sound, in order to better determine the index.
If flotation machine rougher thin foam tank, foam and large number of small scene, bubble glossy color did not change significantly, boiling tank flotation machine, scraped surface foam and foam with the slurry tank fell into a crackling sound, flotation definitely poor. Burghardt observed foam color scan and selected areas of the constituency, the main judge tailings grade and concentrate grade, whether low and high. Last row of foam color is generally shallow surface metallic luster best explanation mineral sorting structured; flotation tank with a gloss dead a foam flotation reagents and other instructions to adjust the appropriate process conditions conducive tailings reduced.
Flotation machine concentrate on domestic goods panning method is difficult to determine the grade of the high and low, can only control the selection of tank foam layer 200-300mm over for good, non-featured operating scraped into the concentrate pulp products, this will help to get high-quality boutique either roughing or fine-election must go to comply with certain principles, because it is not only the right way to improve production efficiency, but also on some of the maintenance and upkeep of flotation devices, increasing its life and can provide more profit for the user. In addition, learn more about some of the issues flotation, flotation beneficiation is very helpful in the production line.
