Análises de processos de cominuição de uma planta de beneficiamento de minério de ouro

Abstract

Gold mining in northern Mato Grosso has been going on for over four decades, but its technological and technical development has not evolved significantly during that time. Good mining practices combined with correct research techniques, mining development, laboratory tests and ore processing, allow the mining enterprise to have a better performance and profitability. Within this context, this paper proposes to carry out analysis of comminution operations and through granulometry tests with the samples collected in the beneficiation plant. In order to carry out these analyzes, the collected material will be, prepared, sieved and quartered, thus carrying out the granulometric tests. The granulometric analysis can indicate the degree of particle reduction, making it possible to see how efficient mineral fragmentation is in the treatment of ores. As it is a beneficiation plant, where the fragmentation equipment is difficult to operate, the desired value of ideal granulometry is not easily reached, being necessary that the material be passed several times in the beneficiation plant.
