| Abstract |
The clarification of plant effluents, particularly those from mineral processing operations, is becoming of much concern for the prevention of stream and lake pollution. The present study was undertaken in order to examine the mechanism of a combined use of a multivalent cation and a polymeric compound, to arrive at a most effective choice in their use as flocculants for the control of water pollution problems, and to establish the effect of size distribution on floc formation and clarification. For prototype solids, quartz and goethite of several different size distributions were chosen. At the same time they constitute the main components of the ore minerals of immediate interest for the iron ore industry of Minnesota. For flocculants, calcium ion and unmodified corn starch were used mainly because their use is well established. The investigation was later extended to include chemically modified starches and polyelectrolytes. |
