The minerals processing industry has made contributions to all areas of technology, both in terms of products and processing. Technologies developed in the mineral industry are used extensively in the chemicals industry as well as in municipal and industrial waste treatment and recycling industry, eg, scrap recycling, processing of domestic refuse, automobiles, electronic scrap, battery scrap, and decontamination of soils.

As indicated above, industrial wastewater contains avast array of pollutants in soluble, colloidal, and particulate forms, both inorganic and organic. In addition, the required effluent standards are also diverse, varying with the industrial and pohutant class. Consequently, there can be no standard design for industrial water-pohution control. Rather, each site requires a customized design to achieve optimum performance. However, each of the many proven processes for industrial waste treatment is able to remove more than one type of pollutant and is in general applicable to more than one industry. In the sections that follow, waste-treatment processes are discussed more from the... 

Treatment-plant wastes. The solid and semisolid wastes from water, wastewater, and industrial waste-treatment facilities are included in this classification. 

To recondition the pots, the potliner is dug out and discarded Prior to discovery of the Spokane aquifer contamination, the procedure had been to remove the pot to an outdoor concrete slab where the pot was filled with water and allowed to soak for a few days to fracture and soften the cathode The contaminated water was presumably reused for soaking and not discharged to the industrial waste treatment system because of the cyanide content The pots were Jack-hammered and the potliner dumped on the slab The potliner was transfered by a front-end loader to an unprotected pile next to the slab ...
