Abstract

Froth flotation was carried out for the recovery of high grade molybdenite concentrate of lubricantuse from the primary concentrate. The re-grinding of the primary molybdenite concentrate should be necessaryin order to further liberate the silicate gangue minerals before the performance of froth re-flotation. But the fineparticle gangue minerals occurred in the re-grinding process make serious bad effect on the froth flotation. Sothe selective rougher flotation was performed on the primary molybdenite concentrate in order to remove thesilicate gangue minerals in advance before re-grinding. And then the molybdenite concentrate recovered by rougherflotation was re-ground for 20min. In test for the recovery of high grade molybdenite concentrate of lubricantuse, we got the molybdenite concentrate of 98.3% MoS2 with 43.5% recovery.

페로몰리용 몰리브덴 정광을 대상으로 부가가치가 높은 윤활제용 고품위 몰리브덴 정광회수를 위한부유선별을 수행하였다. 페로몰리용 몰리브덴 정광에 존재하는 맥석광물들이 단체분리를 위한 재 분쇄 과정에서미립화가 될 경우, 고품위 몰리브덴 정광 회수에 나쁜 영향을 미치기 때문에, 이들을 대상으로 우선적으로 맥석광물을 제거하기 위한 조선부선을 수행하였다. 조선 부유선별에서 회수된 조선정광을 대상으로 단체분리를 위해20분간 분쇄 하였으며, 이때 시료의 평균입도는 약 25 ㎛ 이었다. 실험결과 최적실험 조건은 조선부선에서 회수된 정광을 대상으로 기포제 AF65 30 g/t, 포수제(kerosene) 첨가량 150 g/t, 억제제(Na2SiO3) 첨가량 1,000 g/t,그리고 정선 7회로, 이때 몰리브덴 정광의 품위와 회수율이 각각 98.3% MoS2와 43.5%인 결과를 얻었다.
