Experimental Research on Mineral Processing of High Content of Slime and Finely Disseminated Bauxite Ore
The content of slime was high and the A/S ratio was relatively low,and the objective mineral was finely disseminated,so it was extremely difficult to be separated. Based on the ore property,the measures such as pre-desliming,combination of stage grinding and check classification and adopting the collector of EMLB-2 were taken, and the bauxite concentrate with A/S ratio 9.49 was obtained, at recovery of 80.22% Al2O3. At the same time, the sulphur which contained 46.88% S with recovery of34.14% was comprehensively recycled,and the study could provide technical support for the development of this kind of ore.
By feeding the silkworms with the nano Fe3O4 powder together with mulberry leaves, we directly obtained silkworm spun pristine magnetic silk fiber, MSF. To compare with the normal SF found that this MSF not only has expected magnetic properties, but also has enhanced thermal stability and mechanical properties, e.g. stress and strain.
