The ore will be sent to a SAG mill and thento a ball mill for grinding. In the flotationcircuit, water and reagents will be added tocreate a slurry. The reagents will cause theparticles containing molybdenum to float whenthe slurry is mixed with air, and this allowsseparation of the moly from the host rock. Theworthless ground rock (tailings) is sent to thetailings dams.Recoveries are expected to average 89% formolybdenum. Final concentrate will bethickened, pumped to storage tanks, filteredand dried to be stored in day bins. The driedconcentrate will be packed in supersacks andshipped by truck to offsite facilities.14Key Mill Statistics• Full rates of 28,000 st/d (short tons per day)• 115 people work in the mill facility• 89% Mo mill recovery• Ore contains 0.16% Mo (3 lbs Mo/st ore)• Final product packed in supersacks (3,850pounds each)• At full rates, mill will produce 30 millionpounds of molybdenum per year (over80,000 pounds per day)Key Mill Equipment• 34 ft x 17 ft SAG mill• 22 ft x 36 ft Ball mill• 2 x Pebble crushers• Flotation circuit (with Outotecflotation cells)• 3 x M1000 Isa Mills• 2 x Pressure Filters• Thickener
