On-Stream Analysis

There are many variables in a flotation concentrator, some of which are outside the actual flotation stage, which affect metallurgical performance. The number of such variables which can now be measured on a continuous basis has increased significantly over the past 20 years. They can be broadly classified under the headings of physical, chemical, and elemental. In this paper reference is made to a number of such variables, and comment is made on the state of the art in their measurement. Although not confined to development in Australia, particular reference is made to the considerable Australian contribution in this area of Technology.
