A summary of the procedure includes the following 1)Mining Up the Stikine Alaska Sea GrantHere the ore will be fed into a single gyratory crusher. After the ore has been crushed, it will be conveyed to a single coarse ore stockpile area. To get to this storage area, the ore will travel through a 14-km tunnel built through a mountain. The stockpiled ore will be ground by a conventional single line grinding flotation concentrator.Major Mines & Projects Mowana MineThe coarse ore is reclaimed via two of three sub-level feeders, and is conveyed to a double deck screen fitted with 38 and 15mm mesh. The screen undersize is conveyed to the fine ore stockpile and the oversize gravitates to a secondary Osborne 38 cone crusher. The crushed product is conveyed to one of two 16mm screens in parallel, and the Operation Rio Tinto KennecottOre arrives from the mine at the Copperton Concentrator in about 28 minutes, where it is temporarily stored in a 500,000-ton coarse ore stockpile. Concentrating. In the second step of the production process, we concentrate the ore, which separates valuable minerals from the ore into a Debottlenecking Coarse Ore Conveyor SystemsInstallation of additional stockpile capacity; Dynamic modelling of the coarse ore system is used to determine the average daily sustainable capacity. The annual amount of ore processed is affected by the restrictions imposed by upstream and downstream operations.
