Water scarcity is compelling mining houses to not only recycle process water but also identify alternative sources of make-up in concentrators. South Africa has significant volumes acid mine drainage (AMD) generated from vast operations. This study investigated the viability using AMD as a replacement for potable flotation platinum-group-minerals (PGM)-bearing Merensky ore. Rougher and cleaner ...

The pathogenesis of circulatory shock has been previously associated with the plasma accumulation of a myocardial depressant factor (MDF). The plasma accumulation of MDF in cats subjected to hemorrhagic shock was associated with marked increases (P<0.01) in activities of plasma cathepsins A—E. The pH optima for three of the five cathepsins were in the range of 4.8-5.2, a pH range close to that ...

Current article is devoted to the development of a method for determining polymer functional additives and their molecular weight characteristics in diesel fuel by gel penetration chromatography.
