Impact of silica mining on environment

Pandey and Geenj.Some silica sand mines in the region process the sand on-site however processing is done mainly off-site. Processing begins by washing the sand to remove fine particles (Figure 2). Washing is done by spraying the sand with water as it is carried over a vibrating screen. The fine particles are
