Abstract (en)
[origin: EP0203854A2] Methods for agglomerating mineral ore concentrate by commingling the concentrate with a binding amount of water soluble polymers, preferably poly(acrylamides), and clay, preferably bentonite, are disclosed. The polymer is applied either dispersed in water-in-oil emulsion or as dry powder.
