Plate ESPs are used to reduce particulate emissions from a number of processes in the smelting
of lead, zinc, and copper metals. Since lead, zinc, and copper are found in sulfide ore
deposits, the release of sulfur compounds is a problem during the smelting process. Before
being smelted, ore concentrates are often treated, or prepared, by two processes called sintering
and roasting. Sintering changes the physical form of a material, usually by taking an ore
mixture of large and fine pieces and fusing them into strong, porous products that can be used
in the smelting processes. ESPs are commonly used to reduce emissions from lead and zinc
sinter plants. ESPs are also effective in reducing emissions from zinc and copper roasters.
Roasters prepare zinc and copper ores by removing unwanted materials such as sulfur. The
roasted ore is then sent to other refining processes to produce zinc and copper metals.
