aJRAY Satie?A1c"vg <br /> accordance with DOT regulations and transferred into the reagent room. The old reagent room will be <br /> used to stage chemicals on an as need basis. The Division currently has TR-14 which elaborates on these <br /> topics in depth. <br /> 12. If the two 12,690 gallon slurry storage tanks that are proposed to be installed after the <br /> commissioning of the mill would like to be approved under this certification please provide <br /> the following information; <br /> a. Composition of the slurry stored in the tanks (ratio of ore to water); <br /> b. Their location depicted on the appropriate drawing; <br /> c. A commitment that the size and location of the tanks as proposed is what will be <br /> installed, even if that installation occurs after the mill commissioning. <br /> Response: <br /> a. The slurry tanks will be 20-30%solids <br /> b. The location of the tanks are depicted on drawing 300-GA-004. The details of the tank <br /> construction can be seen on drawings 300-MP-003, 300-MC-006& 300-MC-007. <br /> c. These tanks are currently being constructed and will be 12,690 gallons each. <br /> 13. Section 3.2 Lead Concentrate lists that there are two sets of tanks that make up the Pb Rougher <br /> Scavenger Flotation Cells, and each tank will be 1,320 gallons each. The Pb Rougher Scavenger <br /> Flotation Cells are not listed on Table 1, please update Table 1 to include these volumes. It is <br /> also stated that this stage will create two products, concentrate and tails, please clarify if those <br /> are two separate tanks which would make a total of four tanks at 1,320 gallons each or if the <br /> two products come from the same tank and the system only has two tanks at 1,320 gallons each. <br /> Response: Table 1 has been updated to include the Pb rougher scavenger flotation cells. There will only <br /> be two Pb rougher scavenger flotation tanks. Each tank has three scavenger flotation cells that produce <br /> two products—tails and concentrate. The tails sink to the bottom of the cell tanks and the concentrate <br /> floats to the top. <br /> 14. Section 3.2 it is stated that the slurry enters the Pb cleaner flotation cells which consists of two <br /> banks that both have two tank cells,one at 449 gallons and one at 290 gallons,totaling fourtanks, <br /> two at each respective size. Table 1 only shows one tank of each size, please update table 1 to <br /> reflect the accurate number of tanks in this stage and their volumes. <br /> Response: Table 1 has been updated to reflect the size of the tanks in each of the Pb cleaner flotation <br /> cells. <br /> 15. The narrative details that the tails from the Pb circuit are sent to the Zn condition tanks at 1,064 <br /> gallons each. It is inferred that this means there are two tanks, please clarify the number of Zn <br /> conditioner tanks in this step. <br /> Response: There are two zinc conditioning tanks as shown on drawing 300-PI-006. The updated Table 1 <br /> reflects this. <br /> 41Pa �� � <br />
