| 摘 要： | 以Mac-10为捕收剂，研究新桥硫铁矿高硫含铜矿石降低药剂成本、提高选矿指标的新工艺。结果表明，在石灰用量3kg／t、矿浆pH9．5左右、Mac-10用量48g／t的条件下，采用Mac-10优先选铜工艺浮选新桥硫铁矿，可获得铜品位14．28％、金品位16．94g／t，铜回收率84．47％、金回收率34．42％的铜精矿，与黄药工艺相比，铜精矿品位提高3．97％，铜回收率提高1．26％，铜精矿中金的品位和回收率分别提高7．42g／t和8．64％。 |

| Abstract: | In order to reduce the regent cost and increase the beneficiation indexes of the floatation of copper ores with high sulfur content from Xinqiao Mining Industry Corporation, Tongling, Anhui, China, a novel ore dressing technology using Mac 10 as collector is investigated. The results indicate that under the condition of 3kg/t lime dosage, slurry pH at 9.5, 48g/t dosage of Mac 10, the copper concentrate with copper grade and recovery 14.28% and 84.47%, gold grade and recovery 16.94g/t and 34.42% respectively is produced by new process, the copper grade and recovery are increased by 3.97% and 1.26% respectively, and for gold in copper concentrate are 7.42g/t and 8.64% respectively, comparing to the current flowsheet. |
