Laboratory Flotation Testing An Essential Tool for Ore
2016-11-22 A test of a slow floating platinum ore, for instance, may require 45 minutes to an hour to reach completion and thus the first concentrate can be collected after two minutes of flotation. A faster floating copper porphyry flotation test, however, may finish in five minutes and a first concentrate may need to be collected after 20 seconds.
