found it desirable to obtain a clean quantitative heavy mineral separation to meet the following conditions: 1. Most soils contain minerals in the finer grades that are not represented in the larger size grades. 2. The heavy minerals in the silt grades are so subordinate to the quartz that their determination, if unseparated, is a slow process. 3.
