Caracterização de polpa de minério

Abstract

The rheological characteristics of determined ore pulp depends on their nature, i.e. their physical and chemical properties. The cohesion of the settled material has relevance and is related to certain factors, such as the mineralogical composition of the pulp, the physical and chemical properties of mineral constituents and the distribution of particle size. Through the study of the properties of the pulp you can have an understanding of its behavior in pumping, in this context, the objective of this study is to evaluate some physical and chemical parameters of a given ore pulp. The characterization was performed according to the analyzes of DRX, FRX, ADT/ATG, DTP, MEV, density, viscosity and tests of sedimentation. It was observed in mineralogical composition high concentration of quartz, in addition to minerals from sedimentary rocks as the clay mineral clinocloro, and high cleavage as the biotite. The pulp has a particle size distribution very homogeneous scrolling sizes of up to 22 μm. Therefore the rheological property of a ore pulp as the viscosity is influenced not only by the percentage of solid, but the DTP, ASE, mineralogical composition, ph and temperature.
