【摘要】 在实验室小型试验的基础上进行了连续选矿试验研究。连选试验采用先选方解石而后在酸性介质中脱硅的方案，设备能力为42kg／h，稳定运转72h，各项指标均达到国家“八五”攻关的要求。更多还原

【Abstract】 Based on the experiment in laboratory, the continuous dressing experiment was conductedon low grade wollastonite ores of Lishu. The experiment procedure was desilicating in acidic medium afterremoval of calcite by flotation. The processing capacity of the continuous dressing set was 42 kilogram perhour. All indices of the dressing set running steady in 72 hours reached the demands of the Eighth FiveYear Plan of China.更多还原
