TABLE B1-1 History of Milling and Tailings Disposal Practices in the Coeur d’Alene Basin Site Information Package for National Remedy Review Board Date Milestone 1886 Processing of ore initiated using jigging. 1891 Six mills operating, with a total capacity of 2,000 tons per day 1901-1904 Construction of plank dams on Canyon Creek near Woodland Park and on the SFCDR near Osburn and Pinehurst to control tailings movement. Large volumes of tailings accumulated behind the dams. 1905 Jig tailings from the Morning Mill contained about 8% lead and 7% zinc. 1900-1915 Recovery of zinc initiated during this period. Previously, zinc was not recovered and mills primarily processed low-zinc ores. 1906 Total milling capacity in the basin is 7,000 tons per day. 1910 Flotation introduced in the basin at the Morning Mill. Increased metals recoveries were achieved using flotation. Flotation tailings were finer-grained than jig tailings and were transported greater distances by streams. 1917 Plank dams at Woodland Park, Pinehurst, and Osburn breached by flood waters. 1918 Flotation had been adopted at most mills by this time. mid-1920s Tailings observed in Spokane River. 1925 Flotation tailings from the Morning Mill contain
