Clayey minerals that are prone to slurry formation during grinding tend to produce fine mineral slimes, which deteriorate the flotation environment, increase reagent consumption, and significantly affect the grade and recovery rate of gold concentrates. This study aims to address the beneficiation challenges of this type of gold ore and achieve efficient resource recovery. The research focuses on a low-grade, easily slurry-forming gold ore. Based on a systematic study of its process mineralogy, the research explores the beneficiation process flow, ultimately determining a pre-desliming hydrocyclone, followed by a combined gravity-flotation process using a shaking table. The study sequentially optimizes parameters such as conditioner and collector types and dosages, conducting closed-circuit tests for both the combined gravity-flotation process and direct flotation. After pre-desliming with a hydrocyclone, the use of a shaking table for gravity separation can yield a gold concentrate with a grade of 22.69 g/t and a recovery rate of 21.64%. The tailings from gravity separation, when processed through a flotation circuit with two roughing stages, three scavenging stages, and two cleaning stages, can produce a flotation concentrate with a gold grade of 9.45 g/t and a recovery rate of 68.41%. Compared to direct flotation, the combined gravity-flotation process results in higher recovery rates of gold and silver, and the reagent costs are significantly lower than those of direct flotation. This study effectively addresses the efficient recovery of low-grade, easily slurry-forming gold ores and provides a reliable technical reference for similar gold mines.
