Diseño de propelas para un equipo de flotación Denver D-12 y determinación de la distribución del tamaño de burbuja y su efecto en la flotación de mineral procedente del distrito minero de Chinapintza de la zona de La Pangui.

Abstract

Abstract:The purpose of this work is to create propulsion prototypes for the Denver D-12 flotation cell and the redistribution of the size of the bubble and the effect on flotation with mineral product from the Chinapintza mining district in the Pangui area. The prototypes of properties during the development of the investigation will take the name of property A (Red) and propeller B (Black); the applications are implemented in the equipment for flotation tests under fixed operational conditions. The method used to determine the size of the bubble was made by analyzing images and processes in a software. The factory property and the property were obtained for a yield of 71.09% and 66.34% respectively, being the most efficient in the process, with a bubble diameter size in the range of 0.3 to 0.5 mm; while property B obtained a yield of 34.33%. It is established that each property generates a different hydrodynamic movement, disperses the pulp in different directions within the cell, which allows collision and bubble / mineral adhesion, varying the operational conditions of the process.
