Abstract
The process of sedimentation is successfully used in various industries: from the food and chemical industry, through processing of natural minerals resources in the mining industry. The sedimentation process of suspensions depends on many factors, which mainly include the grain size and grain size distribution of the solid phase of the suspension and its chemical and phase composition. The aim of this work was to determine the basic physicochemical parameters of the suspended solids from coal processing plant for intensification of its sedimentation process by means of multiflux sedimentation and/or flocculation. The particle size (and/or particle size) distribution of solid phase of coal suspension was measured by laser diffractometer. Chemical composition was determined by ICP OES (Optical Emission Spectroscopy with inductively coupled plasma), and phase composition using X-ray diffraction. Both, the chemical composition and grain morphology were verified by SEM / EDS. As a result the shape and grain size distribution of tested suspension was determined as well as it was found that clay minerals such kaolinte and illite are next to quartz dominant constituents at its phase composition.
