The most common dust control technique at mineral processing plants is local exhaust ventilation (LEV) systems. These systems capture dust at the various processes such as crushing, milling, screening, drying, bagging, and loading and then transport this dust via ductwork to a dust collection filtering device.

Local exhaust ventilation (LEV) is an engineering system designed to reduce employee exposure to airborne contaminants such as dust, mist, fume, vapour, and gas in the workplace. It does so by capturing the pollution at source and transporting it to a cyclone / prefilter / filter.

The most common dust control techniques at mineral processing plants utilize local exhaust ventilation systems (LEVs). These systems capture dust generated by various processes such as crushing, milling, screening, drying, bagging, and loading, and then transport this dust via ductwork to a dust collection filtering device.

Conclusion: The results indicate that with designation and installation of the local exhaust ventilation (LEV) system and also installation of bag filter to collect dust, the concentration of...

respirable silica dust, while Chapter 2 discusses dust sampling instruments and sampling methods. Chapters 3, 4 and 5 are focused upon dust control technologies for underground mining, mineral processing, and surface mining, respectively. Finally, it must be stressed that after control technologies are implemented, the ultimate success
