Dewatering of Slurry from Glass Sand Mining

This thesis deals with methods for dewatering technological slurry as a byproduct in the mining industry. The objective focuses on the current sludge dewatering system in the Sklopísek Střeleč a.s. quarry, where only clarifier tanks and gravitational thickening are used for solids separation. The solution is primarily focused on the technology of mechanical dewatering of fine-grained materials. The body of this thesis describes the most used industrial technologies for the processing of sludge from mineral extraction, such as presses, centrifuges, belt presses and drum filters. Laboratory tests mainly affect the mineralogical, chemical and grain composition of the sludge. This thesis will also analyze the investment and operating costs for the acquisition and operation of technology capable of dewatering sludge in larger scaled operations
