Flotation of cobalt and nickel from dilute solutions
Abstract
Currently, methods of precipitation of dissolved substances by various precipitators are most widely used for wastewater treatment of mining and metallurgical enterprises, with the concomitant extraction of metals contained in them. However, bulky equipment for settling, filtration, or centrifugation limits the use of these methods associated with a large expenditure of time. The use of ion exchange resins, given the solid phase in wastewater, is also not always economically justified. The method of liquid extraction from very dilute solutions is associated with significant losses of extractant per unit of extracted metal caused by the solubility of the extractant in the aqueous phase. ...
