Tailings Applications in Waste Containment Layfield Major Mines Projects Morococha Mine
Tailings Applications in Waste Containment Although tailings are deposited hydraulically the main purpose of the containment is to contain the solids produced by mining operations A tailings containment can be either a lined pond or a dam with a dam face lining Layfield has been providing dam facings for tailings containments since the early Classified tailings pumped hydraulically to stopes and waste rock are used for backfill where needed Drilling is undertaken with hand held drills or electric hydraulic jumbo drills and the broken ore is removed using scoop trams Mining of the wider veins and ore bodies has been mechanized with the aim of improving efficiency and operating costs

Mining at the Woodlawn Project will proceed from two independent ore sources fresh ore from underground and surface reclaimed tailings from the existing tailings dams The tailings will be hydraulically mined using a bottom up approach with a channel feeding back to a sumpthe overall tailings management process as it will reduce the amount of water sent to the TSF it produces a viscous material that inhibits segregation of the coarse and fine tailings particles as they are hydraulically deposited which will result in a denser stronger faster rconsolidating tailings
