The aggregate flow of a maximum of 20,000 gpm from the Splitter Box will be <br />distributed to (2) two identical Comag Trains. Each Comag Train consists of one <br />primary vessel sub - divided into (4) four sections designed to mix the solution through a <br />horizontal serpentine flow path. A coagulant is added in the first section of the tanks, <br />magnetite is added in the third section of the tanks, and a flocculant is added in the fourth <br />section of the tanks. <br />Flow then proceeds to the Comag Clarifier. The resulting liquid fraction, known as <br />Enhanced Barren, of maximum of approximately 20,000 gpm is pumped back to the <br />Barren and Enrichment Tanks to be distributed on AGVLF as normal. The product solid <br />component, still quite high in moisture content, will be pumped to the Gravity Thickener. <br />The liquid component from the Gravity Thickener will return to the Comag Trains as <br />makeup water for re -use. The product component (3 -6% solids) from the Gravity <br />Thickener will proceed to the dewatering phase which is a filter press, where a polymer <br />will be added. The resulting dewatered product will be transported off -site for metals <br />recovery. <br />The remaining tanks and storage features will contain relatively benign flocculants, <br />coagulants and product sludge. An important safety feature of the piping between the <br />AGADR and the PSES is a set of valves that close in the event of a loss of power. <br />8.2 Squaw Gulch ADR <br />The SGADR complex will consist of the SGADR building along with a storage area, warehouse, <br />offices, and parking. The area will be similar to the existing AGADR. The SGADR complex <br />will be located on the southwest edge of the SGVLF upgradient of the toe berm on the north side <br />of realigned SH 67. Vehicles will enter from SH 67 with a new access to be permitted through <br />CDOT as discussed in Section 5.8. The complex will be located within a fenced and gated secure <br />area. There will be a guard house at the gate to monitor vehicles entering the facility. <br />The SGADR building and chemical storage areas will be constructed on a graded and prepared <br />foundation within the PSSA lined area of the SGVLF. The grading will be completed on placed <br />ore. Location of the SGADR and associated facilities within the PSSA lined area will allow any <br />drainage from the SGADR surface area to have secondary and tertiary containment as provided <br />by the SGVLF PSSA liner system described in Section 7.2.1 of the Project Description. <br />Concrete flooring for the SGADR will include curbing and floor drains graded to carry flows to a <br />sump which can be pumped to recover any potential spills. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />8 -4 <br />
