FROTH FLOTATION CONTROL

摘要

The present invention is concerned with model-based control of a froth flotation process for concentrating a desired target mineral from ground ore. It exploits real time information about a surface tension of a pulp or flotation solution comprising the minerals. The surface tension represents exemplary additional information about the surface chemistry in the flotation process, and as such enables a refinement of a pulp model used in control of the flotation process. Ultimately, operational efficiency of a froth flotation plant is increased.
