江西九江铜硫矿采用原矿直接加石灰磨矿浮铜的简单流程处理含铜黄铁矿矿床的次生富集带矿石,由于原矿氧化率高和含可溶铜高,问收率较低,多年来浮铜尾矿含铜都在0.7%以上。85年对该矿石进行三种工艺流程比较的小型试验,“酸化—洗矿—浮选与置换”工艺指标最好:原矿品位2.27%,浮 The Jiujiang copper and sulfur mine in Jiangxi Province uses the simple process of direct ore addition with lime to grind float copper to treat the secondary enrichment belt ore of the copper-bearing pyrite deposit. Due to the high oxidation rate and high soluble copper content in ore, Float copper tailings over the years are more than 0.7% copper. 85 years of the ore for three small-scale comparison of the process, “Acidification - washing - flotation and replacement of” the best indicators of technology: ore grade 2.27%, floating
