    Abstract: Separation of calcite ore from other more valuable minerals such as scheelite (calcium tungstate) is effected by a flotation process in which there is used a flotation aid or frother, and a microbial based collector which is produced by growing a culture or mixture of cultures selected from the genus Pseudomonas and/or the genus Alcaligenes, on a hydrocarbon substrate.
