Abstract Scope The reputation of the flotation process to the economies of the industrial world is huge. This method is based on gravity separation that employs the idea of applying rising gas bubbles as the transport medium. Usually, following the selective attachment of bubbles to particles, viz. PGMs. These solid particles are transferred from the body of water to the surface forming a foam. Xanthate is a typical collector that is commonly used in the flotation process. The vital part is to dose the optimal amount of collector in the process. Too much will be costly and challenging to remove afterwards. It is therefore crucial to dose the optimal amount. Mintek has been working on the development of Xanthoprobe, which is an online instrument for measuring xanthate concentrations and is currently looking into developing a control system for xanthate in froth flotation plants. The findings are discussed in this paper.
