Abstract

A crystal size of ore mineral in barite ore from China is less than 160 ㎛ and that of main ganguemineral is less than 80 ㎛. A flotation experiment was carried out on product ground by considering mineralogicaland grinding properties of the barite ore. It was difficult to obtain high grade refined products by direct flotationwhich floats and recovers barite using Aero 827, an anionic collector, because of entrainment and/or entrapmentof fine silicate minerals as well as floating calcite and dolomite. However, reverse flotation with Armoflote 18,a cationic collector could produce high grade refined concentrate(98% of BaSO4) by removing fine gangueminerals effectively. In conclusion, the reverse flotation was more effective than the direct flotation when purifyingthe barite ore from China.

본 연구에 사용된 중국산 중정석광의 광석광물의 결정크기는 160 ㎛ 이하 그리고 주요 맥석광물의결정크기는 80 ㎛ 이하였다. 중정석광의 광물학적 특성 및 분쇄특성을 고려하여 제조한 분쇄산물을 대상으로부유선별 실험을 수행하였다. 음이온 포수제인 Aero 827을 사용하여 중정석을 부유시켜 정광으로 회수하는 직접부선은 주 맥석광물인 방해석과 백운석의 부유뿐만 아니라 미립의 규산염 광물들이 동반부유되어 고품위 정광을얻기 어려웠다. 그러나 양이온 포수제인 Armoflote 18을 사용한 역부선은 미립의 맥석광물을 효과적으로 제거하여 BaSO4 품위가 98%인 고품위 정광을 얻을 수 있었다. 즉, 중국산 중정석광을 정제하기 위해서는 중정석을부유시키는 직접부선보다는 맥석광물을 부유시켜 제거하는 역부선법이 더 효과적이었다.
