    Abstract: 本发明公开了一种脱除高岭土中石英的方法,属于非金属矿高岭土提质加工技术领域。该方法包括:首先用磨矿机将高岭土矿磨细至粒度为0.045 mm以下,再将磨细的高岭土矿与微生物选择性絮凝分离液调配成矿浆,并调节其pH值,搅拌一段时间后静置,使高岭石颗粒沉降,石英颗粒悬浮于选择性絮凝分离液中,分离沉降物与选择性絮凝分离液即可实现高岭石与石英的分离。本发明中选择性絮凝分离液兼具絮凝高岭石和分散石英的能力,可有效脱除高岭土矿中的微细粒石英,工艺流程简单。

    Abstract: The present invention relates to polysaccharides that have been modified by- providing azetidinium functionality thereto. Such functionality can be provided by crosslinking a polysaccharide with a resin having azetidinium functional groups. In one or more aspects, the polysaccharide can comprise one or more of starch, guar gum, alginate or derivatives thereof. Polysaccharides having azetidinium functionality according to the present invention are suitable for multiple uses. Such uses include, but are not limited to, removal of one or more solid materials from a liquid, benef iciation of an ore,- removal of metallic ions from a liquid; providing oil from bitumen; and removal of mercury from synthetic gypsum. Other uses of the functionalized polysaccharides of the present invention include hydroseeding, dust control and corosion control.

    Abstract translation: 本发明涉及通过向其提供氮杂环丁酮官能团而被修饰的多糖。 可以通过使多糖与具有氮杂环丁烷基官能团的树脂交联来提供这种官能团。 在一个或多个方面,多糖可以包含一种或多种淀粉,瓜尔胶,藻酸盐或其衍生物。 根据本发明的具有氮杂环丁酮官能团的多糖适用于多种用途。 这种用途包括但不限于从液体中去除一种或多种固体物质,矿石的益处, - 从液体中去除金属离子; 从沥青提供油; 并从合成石膏中除去汞。 本发明的官能化多糖的其它用途包括氢键合,粉尘控制和腐蚀控制。
