ABSTRACT: A methodological approach and response surface models were developped is this study to predict the
performance properties of paste backfill and optimize its mixture. The predicted properties are the uniaxial compressible
strength (UCS), the slump, solid concentration (solid percent) and cost (based on cement cost) of the backfill. Using a
central composite experimental design, the effect of tailings grain size and density, binders content, W/C ratio on these
