The lead-zinc-containing sludge will be disposed of underground, as mentioned below. Pits and other major cavities will be filled with waste from demolitions of buildings or with waste rocks without lead-zinc mineralization. The storage for lead-zinc concentrates is located in an old marble quarry.

lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of 26–34%. Ores with a mixture of lead and zinc ...

The Sullivan underground lead-zinc-silver mine is located near Kimberley, British Columbia, Canada (Figure 1). The mine operated for 92 years from 1909 to 2001 and was once the world's largest producer of lead and zinc, producing 8 million and 9 million tonnes, respectively. The orebody is considered to be a
