This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue. It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. The basic ideas stressed in this moly flotation …

The floated PGM's will be collected as froth on the launders of the flotation cell. The product will then be filtered and dried in preparation for assay to determine the grade of the PGM product. The assayed PGM product can then be classified as 4E or 6E, in this case Pt, Pd, Rh and so on. We are a Metallurgical testing lab with years of ...
