Formatted Abstract/Summary A number of methods have been used to assess the effect of grind size distribution on flotation response. In general these methods rely on two key assumptions, namely that; the size by size recovery behaviour of minerals in the ore remains constant and there is a deterministic relationship between the cumulative metal and size distribution. This approach has been applied to predict changes in the flotation response of Northparkes ore as a function of changes in flotation feed size (from P80 90 to 150µm). The results obtained from batch flotation tests in a 5 L cell indicate that in general rate constant in a given size fraction is not influenced by the flotation feed size distribution. However at coarser size fractions (greater than 75µm) there is some apparent variation in the rate constant. This is discussed in the context of the degree of liberation of floatable mineral particles in the feed and highlights the value of incorporating mineralogical information into the approach.
