Froth image analysis based on MIA could become the alternative to some instrumentation problems of flotation columns, for instance, to monitor water entrainment. If froth color and/or texture is related to water content, it is possible to build a regression model linking froth image characteristics to the water hold-up of the concentrate.

Metallurgist Mineral Processing Engineer

Problem solving is a process and in many operations this ability is absent. All too often many changes are made together without a solution resulting, on more confusion. Most plants learn to live or survive their problems, not to solve them. The primary strengths of our metallurgists are in Grinding and Froth Flotation Systems in which we:
