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 th…在911metallurgist.com上查看更多信息
