Abstract
This invention is a method for agglomerating mineral ore concentrate comprising the commongling of mineral ore concentrate with a binding amount of a water soluble, high molecular weight polymer. The selected polymer is applied to the mineral ore concentrate either (1) as a dispersion in a non-aqueous medium or (2) as a dry powder. The most preferred polymers are water soluble poly(acrylamide) based polymers.

A process of agglomerating a particulate material consisting essentially commingling said particulate material with a binding amount of water soluble polymer, wherein said polymer is applied to said particulate material as a dispersion in a non-aqueous dispersion medium.
A process of producing pellets consisting essentially of:
- (a) selecting a water soluble polymer dispersed in a non aqueous dispersion medium;
- (b) mixing a binding quantity of said polymer with a taconite concentrate;
- (c) pelletizing in a balling apparatus the mixture of step (b) to form green pellets;
- and
- (d) indurating said green pellets with heat.
