• DESCRIPTIQd OF THE P1mP0.S~D ACTIQd <br />Due to imfawrable market conditions for opal with the ash content <br />(128 - 158) of that from the current Hawks Nest Fast Mine operations, <br />Western Slope Carbon has determined that profitable operation of the <br />Hawk's Nest facility hinges upon cleaning the opal prior to its sale. <br />For this reason, an expansion of the capacity to about 500,000 tons <br />per year and the construction of a coal cleaning plant is proposed. <br />The logistical ocrostraints Linder which Western Slope Carbon is forced <br />to operate both the present and the proposed facility are severe. The <br />map of the facilities shown in Exhibit 1 indicates the extremely limited <br />surface land usage that Western Slope CaLt~on has been able to acquire. <br />The proposed cleaning plant will be located adjacent to the East Mine. <br />Coal will be transported from the 600-ton opal bin on a ocmveyor which <br />will carzy it into the cleaning plant (ca~Qletely contained). Coal <br />• entering the cleaning plant at 150 TPH is contined with water at 96,000 <br />GPH in a diaphragm jig. A detailed flora sheet of the proposed facilities <br />operation is shown on Exhibit 2 (inside back mver). <br />Higher density material (refuse) will be sent directly to dewatering <br />screens and immediately dropped onto a conveyor belt feeding a 25-ton <br />refuse bin. This portion of the refuse will retain about 128 surface <br />moisture. <br />From the jig, the lic~ter coal will go to a dewatering screen where three <br />size fractions will be produced. the 3" x 1 1/8" fraction with about 4$ <br />surface moisture goes directly to the product belt. The 1 1/8" x 28m <br />fraction goes through a centrifuge where its surface moisture is reduced <br />to about 78 and then loaded onto the product belt. The 28m x 0 fraction <br />with mist of the water added in the jig will go either to a sludge screen <br />or a refuse filter. Most of the water extracted will be recycled. The <br />only water leaving the plant will be in opal or refuse. The clean coal <br />• and refuse will be loaded out on their respective belts. <br />-7- <br />
