Abstract: This article evaluates the efficiency, benefits and limitations of pre-concentration by density separation for process mineralogy studies of low-grade gold ore. The preconcentration by density aims to generate a product with a high content of gold and to maximize the number of gold-bearing particles characterized, thereby increasing the representativity and reducing the number of polished sections to be analyzed. Preconcentration by density was carried out for a low-grade sulfide gold ore (0.96 ppm) from the n… Show more
