fine ore bin to complete milling processes of primary grinding in ball mills, primary concentration by flotation, cleaner concentration and then filtering , drying and packaging. Circuit improvements will occur in keeping with the highest technologies. Most of the product is shipped to Climax' s domestic and foreign conversion plants. By-products include tungsten, tin and pyrite concentrates. Slurried tailing from the mill is delivered by gravity to three tailing deposition ponds. 2. 7 TAILING DEPOSITION Tailing deposition sites include the Robinson Tailing Pond (.13) _(approximately 861 acres including its two Dams , No. 1 and No. 2 Dams ( 14 and 15 ) , located directly north of the mill site upon the natural divide between the Eagle River and Tenmile Creek drainages ; and the Tenmile Tailing Pond (22) ( approximately 613 acres including its Dam, No. �3 Dam (23) ) located at a lower elevation north of, and contiguous with the Robinson Tailing Pond; and the Mayflower Tailing Pond (31 ) ( approximately 406 acres including its Dam, No. 5 Dam) located approximately five miles north of the mill at a lower elevation than the Tenmile Tailing Pond . Its ultimate acreage will be 1 , 280 acres including its Dam. The crest of the No. 5 Dam will be approximately 515 feet high and have an overall face slope of 4: 1 . No. 1 , No. 2 and No. 3 Dams have face slopes of approximately 3: 1 . The Robinson Tailing Pond will remain active probably through the midyears of Phase III or approximately 1990 , while the Tenmile and Mayflower Tailing Pond will function for the life of the mine. Approximately 75,_000 . oubic_ yards of topsoil have been stripped from the Mayflower tailing area to date . A total of approximately 300, 000 cubic yards will be stripped fr-or�_-the__area during Phases II and III . The topsoil will be _sired immediately for reclamation purposes or stockpiled ( 35 ) for the near future reclamation projects. 2-9 f
