Sullivan Mine
Canada

The Sullivan Mine is a now-closed conventional–mechanized underground mine located in Kimberley, British Columbia, Canada. The ore body is a complex, sediment-hosted, sedimentary exhalative deposit consisting primarily of zinc, lead, and iron sulphides. Lead, zinc, silver and tin were the economic metals produced. The deposit lies within the lower part of the Purcell Supergroup and mineralization occurred about 1470 million years ago during the late Precambrian (Mesoproterozoic).

The deposit was discovered in 1892 and acquired in 1909 by the CPR-owned Consolidated Mining and Smelting Company of Canada (later Cominco Ltd. and Teck Cominco). The mine's economic success resulted largely from Sullivan's 1916 development of the differential flotation process that allowed separate recovery of lead and zinc concentrates in the milling process. This technology, developed by Trail operations at Sullivan,[3] has been used worldwide for various types of ore bodies. In its lifetime, the mine produced over 160 million tons of ore containing 8 million tons of lead, 7 million tons of zinc, and 285 million troy ounces (8.9×10g) of silver, which were together worth more than $20 billion. After 92 years of active production, the Sullivan Mine was closed in 2001. Since then Teck Cominco has been undertaking an extensive decommissioning and reclamation process at the site.
