<br />5. Tailings from the Mill will be stacked south of the <br />i~~ <br />Mill on terraces 50' wide.' The terraces will be 5' in height giving <br />the tailings pile an overall slope of 10%. Tailings will be thickened <br />to approximately 70% solids and pumped to cyclones which will <br />discharge the sands to the pile. The cyclones will be moved over <br />the terrace to deposit a F" layer of tailings and slimes will be <br />sprayed onto the previously deposited layer of sands. The entire <br />pile area will be bermed and any drainage from-the pile will be col- <br />lected and pumped to the Mill. <br />The area of the tailings pile will be 12.7 acres when <br />~~ <br />the present reserves are exhausted. Deposition of tailings will <br />average 2.5' per year in depth. Chemical binders and reclamation <br />by planting of grass and shrubs on a continuing basis will be used <br />for prevention of-wind erosion. <br />Exhibit ~ shows the proposed tailings disposal system. <br />Mill Process <br />The mill feed is stored in 50 ton storage bins until it <br />J~ <br />is run through the crushing plant and reduced to 80% minus 5/16 inch <br />size and stored in the fine ore bin. The finely crushed ore is then <br />mixed with water and fed into the ball mill where it is ground to <br />80% minus 200 mesh. The slurry is then fed to the flotation cells <br />where a frother and collector are added and air is infected to float <br />the concentrate away from the gangue. The concentrate is pumped <br />to a drum filter where the water is removed from the concentrate, <br />this water is then recycled to the circuit and the concentrate is ready <br />for shipping. Tailings from the flotation circuit are piped to a <br />-~ 1t~4377 <br />
