Melhoria do sistema de preparação do coletor para flotação de apatita através de medidores de vazão

Abstract

A mining company located in Serra do Salitre, Minas Gerais, faces challenges with a collector and depressor preparation tank used in apatite flotation for phosphate concentrate production. Currently, the tank filling control is carried out by level meters, which show low accuracy and compromise the precise proportions required for the preparation of the collector and depressor. These chemical reagents require an exact quantity of water, soybean oil, soda, and starch. In this context, this work proposes a project for replacing the preparation system with flow meters, providing greater precision and standardization in the collector batches. This change will result in more accurate dosing of the reagents in the tank, ensuring higher quality and reduced variability over time in the mineral flotation process.
