Main design options and characteristics of underground mineral processing are presented in Table 5. A more conservative underground mineral processing facility would preconcentrate the ore in order to reduce the amount of material transported to surface, thus leaving a significant portion of the waste behind for backfill (Morin et al., 2004).

At most metallic mineral processing plants, each process operation requires several types of equipment. A single crushing operation likely includes a hopper or ore dump, screen(s), crusher, surge bin, apron feeder, and conveyor belt transfer points. Emissions from these various pieces of equipment are often ducted to a single control device.
