From environmental, health and safety point of view most mineral processing operations have some negative effects on the working environment. The main problems are related to
  • Dust
  • Pollutant gases
  • Industrial Effluent

 Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers.

Pollutant gases
 Same as another industries, mineral processing produce lots of pollutant gases which mostly is fossil fuels combustion products. Other types of these gases might be toxic and hazardous for workers, around houses and for the environment. Applied government standards force factories to use catalysts, filters and other methods to decrease pollution of emission gases.

Industrial Effluent
 There are many types of industrial effluents based on different industries and contaminants; each sector produces its own particular combination of pollutants. Like the various characteristics of industrial effluents, the treatment of industrial effluents must be designed specifically for the particular type of effluent produced.
