Obtenção da fração argila do saprólito de filito utilizando hidrociclonagem

Abstract

The hidrociclonagem is a process of classification which have wide application in the field of mineral processing. Its principle of separation is based on centrifugal sedimentation. It is used in the separation of fine particles (clarification and dewatering), oil purification refrigeration, regeneration of drilling muds and thickening. Their effectiveness depends on the size of hydrocyclone, of the operating variables, the physical properties of solids and pulp fed. Due to its importance in the classification of fine particles, decided to make this work, to evaluate how the hydrocyclone, in fine fractions as phyllite, define the cutting diameter, analyze the influences of major operating variables of hidrociclonagem and propose a model of methodological plan for the use of hydrocyclone. And with the theoretical analysis and experimental, resulted in the efficiency of hydrocyclones the classification of fine particles such as sand and phyllite.
