The next test reagent is Cytec Reagent S-11194 (SDS attached). The testing will be identical to the Polyfroth <br /> H28C. Climax expects to use -110-150 cc/min in the cyclone overflow and --10-50 cc/min in the TK-053 (4 rougher <br /> flotation cell), a maximum of 200 cc./min total which will be around 0.02 lbs. reagent/ton ore. In both cases a LMI pump <br /> will be used to add the frother to the circuit. Climax will bring in one tote (- 275 gal)for the test. The test is anticipated <br /> to start in late April -early May and last for about 9 to 10 days. In case we see any issues with our process from the <br /> test reagent we will discontinue the test and dispose of the remaining chemical in accordance with waste regulations. <br /> The tote will placed on the cyclone deck on the grinding side of the mill where we have concrete floors and a sump to <br /> provide both secondary and tertiary containment in case of spills. We will update the EPP if we decide to make this a <br /> permanent change. <br /> Please let me know if you have any concerns with this test. <br /> Thanks, <br /> Raymond Lazuk <br /> Environmental Manager <br /> Climax Molybdenum Company <br /> Climax Mine <br /> HWY 91 - Fremont Pass <br /> Climax, CO 80429 <br /> Office: 719486-7584 <br /> Cell: 719-201-1282 <br /> raymond_lazuk@fmi.com <br /> 3 attachments <br />
