<br /> <br /> <br /> <br /> <br /> <br /> <br />10. 4later Rights <br />By efficiently recycling water in the milling process, the amount <br />of makeup water is minimized (approximately 1,400 gallons per <br />day). This makeup water will be drawn from North Clear Creek <br />where CCCM owns two shares of Mead and Polar Star Extension Ditch <br />water rights (Figure 8). <br />11. Processing and Milling <br />All ores will be processed in the Golden Gilpin gold mill. The <br />mill will employ a flotation circuit to recover the contained <br />metal:;. No cyanide will be used in the Golden Gilpin mill. The <br />basic flow sheet for the Golden Gilpin mill is shown on Figure 6. <br />The Golden Gilpin mill will process approximately 75 tons of ore <br />per day and produce approximately 7.5 tons of concentrates per <br />day ('10 to 1 reduction). The concentrate will be trucked in bulk <br />loads to out of state smelters. <br />' CCCM anticipates crushing ore to approximately -100 mesh. <br />Following crushing, the ore will report to the flotation circuit <br />for processing. The only chemicals to be used in the flotation <br />' circuit are conventional flotation reagents. Reagents used will <br />include caustic soda, soda ash, sodium silicate, Aero 242, 343 <br />and 404. The chemicals used in the flotation circuit will be <br />standard, mostly surface active reagents that are non toxic in <br />process concentrations and mostly remain with the concentrate <br />fraction rather than in the tailings. <br />' The chemicals used in the flotation circuit are typically <br />purchased in 55 gallon drums in a liquid concentrate form. Drums <br />will be stored in the Golden Gilpin mill and batches of dilute <br />' reagent will be mixed daily. The storage area has a concrete <br />floor with curbing and is sloped to a sump for spill containment. <br />In addition to the normal lead, zinc and copper sulfide <br />concentrates that will be recovered in the Golden Gilpin <br />flotation circuit, CCCM intends to install a final flotation <br />cleanup circuit in the Golden Gilpin mill that will recover <br />' pyrite. As a result, the tailings discharged from the Golden <br />Gilpin mill will essentially be free of all acid generating <br />sulfide minerals. <br />' CCCM intends to discharge the tailings from the Golden Gilpin <br />mill into a series of four ponds (Figure 4). Pond 1 is the <br />primary settling pond where the coarse fraction of the tailings <br />' discharge will be allowed to settle out of solution. Pond 1 has <br />a storage capacity of approximately 3,000 cubic yards. <br />' Ponds 2 through 4 are additional ponds where progressively finer <br />fractions of the tailings discharge will be allowed to settle. <br />Ponds 2 and 3 have a storage capacity of approximately 200 cubic <br />' yards each. Pond 4 is a solution treatment pond with little <br />storage capacity. <br />' C 6 <br />
