Abstract: Fluid contaminants may be prevalent in many industries, such as the mining industry. Functionalized saccharide polymers comprising two or more monosaccharide units linked by glycosidic bonds and having a portion of the monosaccharide units oxidatively opened and functionalized with at least one aminocarboxylic acid covalently bound through nitrogen at a site of oxidative opening may be utilized in conjunction with fluid remediation processes, such as froth flotation. In non-limiting examples, the functionalized saccharide polymers may also be useful for promoting dust control, particulate coating, clay stabilization, and various subterranean treatment operations. Glycine represents one example of an aminocarboxylic acid that may be covalently bonded through nitrogen at a site of oxidative opening.

Abstract: Loose particulate materials can be problematic in various aspects. For example, loose particulate materials may generate dust or be difficult to consolidate together. Fines in loose particulate materials may also be an issue. Coated particulates may alleviate some of the foregoing issues. Suitable coated particulates may comprise a particulate material comprising sand or a ceramic, and a polysaccharide composition coated upon the particulate material, the polysaccharide composition comprising a functionalized polysaccharide. Other particulate materials such as wood chips and animal litter particulates may be coated with functionalized polysaccharides to achieve similar advantages.
