【摘要】 分析了陕西某高碳金矿的矿石性质,进行了浮选、氰化及焙烧+氰化工艺对比试验研究,结果表明:采用焙烧+氰化工艺及煤油屏蔽未完全燃烧的残留碳能有效提高指标,并对含碳金矿难选原因进行了分析。更多还原

【Abstract】 Based on the property analysis of a fine high-carbon gold-bearing ore in Shanxi,a series contrast tests on flotation,cyanide and roasting + cyanide were carried out.The test result showed that the roasting + cyanide with kerosene shielding the unburned carbon can improve the index effectively.The reasons of causing ore hard to treat were also analyzed.更多还原
