Abstract:
The invention relates to an organic ore pelletizing aid, to a method for making it, and to a method for pelletizing ore using the pelletizing aid. The pelletizing aid comprises coal which has been treated with an alkali metal hydroxide. A particular advantage is the provision of good ore ''''ballability,'''' even at relatively high moisture content. The pelletizing aid may be coated with a high molecular weight, water dispersible organic polymer to further improve its performance.
