Abstract: Water-soluble graft copolymers of acrylic acid and a watersoluble polyhydroxy polymeric compound, including water-soluble salts thereof, are useful as binders in the agglomeration of finely divided materials. The graft copolymers are especially useful as binders in the pelletization of minerals and ores, such as taconite.

Abstract: An ethylene/vinyl acetate resin copolymer mixed with paraffin wax coats and binds finely divided materials compressed into a briquette for addition to molten metal. The binder, which forms a minor portion of the total briquette, may be extended by first coating one of the finely divided materials intended for incorporation in the briquette whereby a very small percentage of the binder is thoroughly and evenly distributed throughout the briquette.
Abstract translation: 与石蜡涂层混合的乙烯/乙酸乙烯酯树脂共聚物，并将压碎成块状的细碎的材料粘合到熔融金属中。 形成总团块的较小部分的粘合剂可以通过首先涂覆用于掺入到团块中的细碎材料之一来延伸，由此非常小百分比的粘合剂被彻底均匀地分布在整个团块中。

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。
