Deo, N and Natarajan, KA (1997) Surface modification and biobeneficiation of some oxide minerals using Bacillus polymyxa. In: Minerals and Metallurgical Processing, 14 (3). pp. 32-39.Full text not available from this repository.
The interaction of Bacillus polymyxa and minerals such as hematite, corundum and quartz resulted in significant surface chemical changes, both on the cell surfaces and on the interacted oxide minerals. After such treatment, quartz was rendered relatively more hydrophobic, while hematite and corundum were rendered more hydrophilic. Biopretreatment was observed to be beneficial in the separation of silica from hematite and alumina by both selective flocculation and flotation. The possible role of bacterial adhesion and metabilites in the biobeneficiation process is illustrated.
