Establishing the Relationship between Grind Size and ...
In this paper, three different techniques that establish a relationship between grind size and flotation recovery are reviewed. The models are developed using data collected from an industrial flotation circuit. The predicted grind size versus flotation recovery relationship produced from the different techniques has then been compared.
