摘要

Use of micro screen in effective separation for specific cut size and recovery of valuables from spiral tailings of beach sand is discussed. With increasing deck angle of micro screen from 50° to 74°, the specific cut size of the spiral tailings decreases from 100 to 45 micron. The overflow of micro screen containing 86% of material may be rejected, incurring overall loss of only 0.37% of heavy minerals. The screen underflow that gets enriched in heavies (19.3%) may be recircu-lated to the plant, so that higher recovery of such heavy minerals can be achieved.
