    SummaryDescription of Apparatus UsedExperimental MethodsResults of Attrition Scrubber TestsOther Methods of Scrubbing as Compared to Attrition ScrubbingAn attrition scrubber was built and tested in the scrubbing of four Western carnotite and two Western roscoelite ores. The tests showed that the sand product increased in purity as the amount of work put into the scrubbing increased, the time of scrubbing being of maximum importance. Speed, pulp density and size of charge had progressively less effect on the purity of the sand product.Metallurgically, there is small choice between the quality of work done by the attrition scrubber and some ot...

  • Froth Flotation of Iron Ores - sapub

    With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

    If clays are not liberated, the final frac sand product could fall outside required turbidity specifications. The general use of attrition scrubbers is to break down these clays, whether found in sand size particles or as coatings on the surface of sand grains, to allow for their rejection. Attrition scrubbing cannot change or alter the grain shape.
