摘　　要：研究了云南某难处理硫化金精矿在加压氧化过程中硫的最低自热品位。在设定条件下,采用热量衡算法,获得了矿浆在不同含固量条件下的硫化金精矿硫的最低自热品位,并对变化曲线进行拟合,推导出硫的最低自热品位计算公式。该研究结果对难处理硫化金精矿的开发利用有一定的参考价值。Lowest sulfur self-heating grade in pressurized oxidation of a refractory sulfide gold concentrates from Yunnan was studied. Under the setting conditions, the lowest sulfur self-heating grade of the sulfide gold concentrates with different solid content in slurry was obtained by the heat balance method,and the calculation formulas for sulfur lowest self-heating grade were derived by curve fitting. The relative deviations of the formulas are small by verification. The formulas have good reference value for development and utilization the refractory sulfide gold concentrates.
