mixer will accomplish the thorough mixing. A small valve and garden hose type pipe will <br />allow the mixed solution to flow to the sluice box where the mixture will be allowed to <br />enter the slurry from the sluice where the flocculation of the fine particles in the sluice <br />tails pond will take place. The chemical is used in very small quantities and the solids <br />should settle very rapidly, based on experience at other sites. The sluice tails pond is <br />actually an old mining area which will be backfilled by the sluice tails and the <br />flocculation effort. <br />The 55 gallon steel drum, the 100 gallon mixing tank and 150 gallon water tank will all <br />sit inside a metal stock tank of a minimum of 10 feet diameter and 2 feet tall, which is <br />more than enough to contain 110% of all tanks being ruptured. <br />The expected wet chemical use with water will be at the ratio of 1 gallon liquid chemical <br />per hour for the expected flow rate of 2500 gallons per minute. This was determined from <br />a laboratory test conducted by Hychem on the actual dirty water at the Alma Placer. <br />Therefore, since the gold operation uses a process flow rate of 2500 gallons per minute <br />for an expected 10 hour day, the chemical will be used at the average rate of 10 gallons <br />per day. <br />See enclosed data from Hycbem and Tons Per Hour Company. <br />The flocculent will allow all solids to settle out in the initial area of the sluice tails pond. <br />The pond has a fine clay and silt bottom so there is no threat of chemical traveling into <br />groundwater, in addition to the fact that the chemical is -used in so low concentrations that <br />the water is completely safe under all circumstances. Also, the chemical is not toxic to <br />animals or people in dry or wet form. This pond is actually an older, mining area that was <br />not fully backfilled. This sluice tails pond discharges to another large lower pond where <br />clean water is recycled to the sluice. The sluice tails gradually reclaim the sluice tails <br />pond to its final configuration. The lower pond does not discharge to the surface. <br />3. Sluice Tails Pond Cleanout <br />Using the laboratory test result of 3.4 %. solids in the dirty water, this means that for a <br />total flow of 330 cubic fect/minutc, the solids arc 11.3 cubic feet per minutc. Assuming <br />that the settled solids have 40% water by weight, this means that 15.8 cubic feet/minute <br />
