Studying an opportunity of application water-soluble high-molecular substances for suspensions flocculation

Appreciable influence of рН environment on average speed sedimentation of researched suspensions is revealed. The index of reactionary ability (glocculating effect) of added reagents in the interval рН 1,067÷8,110 is estimated. Optimum pH value and time of effective suspensions flocculation by means of the researched high-molecular substances is certain. It is established, that preliminary coagulation of disperse systems raises the efficiency of subsequent flocculation. The basic technological scheme of application the picked up reagents for heavy metals extraction from sewage of the copper complex mines is offered.
