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.
Abstract translation: 本发明涉及有机矿石造粒助剂,其制备方法以及使用造粒助剂造粒矿石的方法。 造粒助剂包括用碱金属氢氧化物处理过的煤。 特别的优点是即使在相对较高的含水量下也能提供良好的矿石“球形性”。 造粒助剂可以涂覆高分子量的水分散性有机聚合物,以进一步提高其性能。
