Abstract

This investigation is concerned with the comparison of the advantages and disadvantages of subsieving techniques widely used in mineral processing throughout the world. With this purpose, the subsieving techniques of Andreasen pipette, Coulter counter, and laser diffraction methods were compared each other by determining the relationship between specific surface area and particle size distribution. In the tests, the two different standard quartz sand samples (A and B) from the Official Material Testing Institute for Nonmetallic Minerals, Clausthal-Zellerfeld with a particle density of =2.65g/cm(3) were used. As a result, the Coulter counter method had the most favorable results in terms of calculated specific surface areas of 3848cm(2)/g for sample A and 2852cm(2)/g for sample B, with standard deviations 41.29 and 32.48, respectively.
