<br /> <br />Classifier overflow products will be fed through a 30" <br />x 36" drum-type magnetic separator to remove any magnetic <br />iron particles. In addition to initially upgrading the mill <br />feed accomplished by the removal of the magnetic fraction, <br />we anticipate a market for the magnetic iron recovered. A <br />further benefit of this process will be to prevent the <br />magnetic iron from being ultimately disposed of in the <br />tailings disposal area. <br />Concentration by gravity methods will be accomplished <br />by two 8" x 12" duplex jigs set in series and final cleanup <br />and recovery, with two full-size shaker tables set in <br />parallel. <br />Mineral recovery with use of the flotation process will <br />be accomplished by, first, removing the magnetic fraction <br />then recovering salable mineral products using conventional <br />flotation process. Reagents used will be: <br />Promoters - Cresylic acid base or zanthates <br />Modifiers - Lime, caustic soda, soda ash, starch, <br />caustic soda, copper sulphate <br />Depressants - Lime, zinc sulphate <br />Normal flotation reagent consumption 3s estimated to be <br />less than 1/10 lb. per ton of ore treated. All reagents <br />will be stored in upright 55-gallon barrels in the reagent <br />storage room. Only one day's operating supply will be in <br />the reagent feeders at any one time. <br />
