1. Quartz and pyrites (FeS2) are separated by continuous hydraulic classifications using free settling in water at 293 K. The feed to the classifier ranges in size between 500 microns and 1,000 microns. Three fractions are obtained: a pure quartz product, a pure pyrites product, and a mixture of quartz and pyrites. The specific gravities of quartz and pyrites are 2.65 and 5.1, respectively. What is the size range of the two materials in the mixed fraction? "
