Abstract
The Saerhabutale kyanite deposit in Gansu Province originates from garnet kyanite two-mica quartz schist,whose complicated component brings large difficulty to achieve effective separation.According to the characteristics of the deposit,we innovatively used the following technical process to recycle kyanite ore:" crude ore-crushing-dry magnetic tailings discarding-grinding-tailing discarding via spiral chute-grinding again-kyanite flotation-iron removal"by magnetic separation.The result was that the kyanite concentrate yield was 7.15％,the grade of Al2O3 was 58.74％ with the recovery of 20.97％ and the kyanite mineral amount was 95.26％ with the recovery of 75.53％.Chute tailings were adopted"sieving-reelection-magnetic sepatation" process to recycle muscovite(white mica),while the dry magnetic tailings were adopted" reelection-sieving-magnetic scpatation" to recycle garnet,muscovite and biotite(black mica).The result was that the muscovite concentrate rate was 17.57％ with the mineral amount of 98％,the biotite concentrate rate was 9.48％ with the mineral amount of 90％ and the garnet concentrate yield was 3.36％ with the mineral amount of 95％.The test shows that,except the kyanite is available to exploit,associated minerals as garnet,muscovite and biotite could also be comprehensively recovered and utilized in this deposit.The quality standard of the final product of kyanite concentrate meets the national standard LJ-52.关键词
