Tailings filter cake at a target moisture content of 15% will be conveyed to a temporary <br /> stockpile on a concrete pad immediately outside of the mill building before being hauled by <br /> a truck to the FTST for storage as described in Section 2.4.6.4. <br /> 2.4.5.5 Volumes of circuits, types of vessels and conveyances and materials to be used in <br /> construction <br /> The mill will house various sizes of bins,tanks, conveyors and other major equipment as follows. <br /> Equipment Description&Type Nominal_Cap 1 Size or Model r #of <br /> '-------""-----""--------------------------------'"""----------------------YC""""""""""""""""""`"""""""""""""""""""""""""""""""""""C"""" `-.1-"""""":------------------------------------------------------------------------------------------' <br /> -Coarse Ore Dump 1-Hopper -50 t Live 322 ft3 Live 1------ ----------------------------------- - <br /> -------------------------------------- <br /> Fine Ore Bin 300 ton Live 22 It Dia.x 27 It 6,100 ft3 1 <br /> ------------- <br /> Crushed Ore Conveyor 20 In x 236 ft 1 <br /> ----------------------------------------------------------------------------------------- <br /> Secondary Screen Feed Conveyor 201n x 173 It 1 <br /> --------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Ball Mill Feed Conveyor 301n x 40 It 1 <br /> ---------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Primary Ball Mill 8 It Dia x 12.33 It Egl 1 <br /> -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Rougher Flotation Cell 100 ft3 D-R 30 9 <br /> -----------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Regrind Ball Mill 1.5 m Dia x 2.7 m Egl 1 <br /> ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Cleaner Flotation Cell 100 ft3 D-R 30 4 <br /> ----------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Concentrate Thickener Tank 15.4 ton/d solids 8.3 It Dia 1 <br /> ----------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Concentrate Filter Feed Tank 225 ft3 6.6 It Dia x 8 It H 1 <br /> ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- <br /> Tailings Thickener Tank 360 ton/d solids 60 It Dia 1 <br /> '---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------' <br /> Tailings Filter Feed '•, Tank 2,200 ft3 13.3 ft Dia x 16.6 ft H 1 <br /> ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- <br /> --------------Tailings-Filter-Cake _ Conveyor '--------------------------------------------------------- 361n x 40--tt-------------------------------------------------------- <br /> The following tanks will be located outside the mill building. Each tank will have individualized <br /> secondary containment as a berm that will have 110%volume capacity. <br /> • The un-named tank located at the top of drawing 15561-3000-GAD-100 is the tailings <br /> thickener tank(4010-THT-002). It will contain final mill tailings slurry prior to filtration. <br /> • The tailings filter feed stock tank(4020-TNK-009)will store densified tailings thickener <br /> underflow for intermittent feeding to the tailings filter inside the mill building. <br /> • The tailings filter cake storage is where the tailings after filtration will be stored prior to <br /> loading onto trucks for haulage to the tailings storage facility on a shift basis. <br /> • The process water tank(6024-TNK-005)will contain process water received from <br /> various areas of the mill, including overflow streams from the tailings and concentrate <br /> thickeners,filtrates from both filters. <br /> • The filtered &fire water tank(6025-TNK-006)will contain filtered water suitable for use <br /> in mixing reagents in the upper section while the bottom section will be used for <br /> firefighting should this be necessary. <br /> 2.4.5.6 Reagents <br /> Flotation chemicals for use in the milling operation will be stored on site. The following are the <br /> reagents and their consumption rates that will be required for the process: <br /> • Potassium Amyl Xanthate (PAX), a sulphide mineral collecting agent, powder <br /> form, 0.25 lb./ton <br /> • Methyl IsoButyl Carbinol (MIBC), a frother, liquid form, 0.1 lb./ton <br /> • A generic anionic emulsion flocculent, liquid form, 0.05 lb./ton <br /> 26 <br />
