Metodologia para controle de qualidade de minério e destinação de blocos de lavra usando raios-x

Abstract

Currently, ore with high-grade and facility of exploitation, have been issued or no longer exists. Nowadays, we have small, deep and deposits low-grade therefore, the introduction of new technologies and detailed studies are extremely important for suitable control and quality of available minerals. In mining enterprises, one of the major challenges is the difficulty of maintaining a beneficiation plants, operating with appropriate grade of ores resulting a better performance for the operation. The geological knowledge of the different types of lithology in a mine, is a very important stage to ensure the expected quality of the ore, however this is not enough in most cases. Generally, materials that comes from mine does not permit be controlled by expeditiously or visually way. Thus, the application of a reliable and fast method of checking and sampling is required. This study in a limestone mining called: "Ore quality control methodology and allocation of mining blocks using X-rays," introduces implications of the method which requires for a positive results the suitable layout for ROM (Run of Mine) based on quality control of the ore forwarded to the beneficiation plant for becoming a requirement in economic and environmental terms. Through this study, will be clear benefits such as reducing the amount of overburden and tailings, reducing of areas affected by deposits, less equipment wear, contributing to the reduction of production costs and consequently increasing profitability.
