Dedicated in April 2005, the Max Bowen Mineral Processing Laboratory is used by mining and metallurgical engineering graduate students to carry out research projects. Undergraduate students also gain hands-on laboratory experience performing mineral liberation processes learned in Introduction to Mineral Processing (MNGN 322), including:

Mineral processing waste streams typically bear little or no resemblance to the materials that entered the operation, producing product and waste streams that are not earthen in character. Twenty mineral processing wastes (see side bar) qualify for the exclusion from federal hazardous waste regulation.

2007/4/26Residues from aqueous processing contain a variety of arsenical materials which have not been characterised, and the long-term stability of these is suspect The use of lime to stabilise aqueous residues as cither calcium arsenate or calcium arsenite has been shown to be inadequate for long term disposal since both compounds are converted into calcium carbonate due to the influence of carbon

Regulation affecting mineral processing wastes was developed through a long process covering the period from 1980 to 1991. It involved numerous proposed and final rule makings and federal litigation. Twenty mineral processing wastes, specified in the September 1, 1989 final rule (54 FR 36592) (PDF) (52 pp, 7.2MB, About PDF ), qualify for the Bevill Exclusion as "low toxicity, high volume

Material used for backfill can be waste rock, tailings or water treatment sludge, and to increase strength they may be

2011/6/1The direct disposal of mining and mineral processing wastes into rivers, oceans and lakes presents significant technical, social and environmental challenges to sustainable development. Riverine tailings disposal (RTD) is the direct discharge of mine process tailings into rivers.
