【摘要】:基于表面性质在矿物加工领域的重要性及低温等离子体的改性优势,从产生方式、改性原理和应用途径3个方面综述了低温等离子体在矿物加工领域的应用现状。低温等离子体具有足够高的能量可使反应物分子激发、离解和电离,破坏材料中的化学键,可以快速脱除煤中有机质而不破坏矿物组成,使有机质被活性氧氧化、脱除,得到性质基本未变的矿物质,为分析煤中矿物质的组成,无机质基本性质提供了良好的条件;等离子体环境下,不同矿物的表面改性行为不同,可以扩展不同矿物的表面性质差异,为难浮矿物的分选提供了新途径;等离子体产生臭氧具有很强的活性,可与废水中的有机药剂反应,能有效降解废水中的有机药剂残留,并可用于浮选、煤泥水处理药剂的改性等方面,应用前景广阔。
[Abstract]:Based on the importance of surface properties in the field of mineral processing and the advantages of low temperature plasma modification, the applications of low temperature plasma in mineral processing are reviewed from three aspects: generation mode, modification principle and application approach. The low temperature plasma has sufficient energy to excite, dissociate and ionize the reactants, destroy the chemical bonds in the materials, remove the organic matter from coal quickly without destroying the mineral composition, and make the organic matter oxidized and removed by reactive oxygen species. The basic properties of minerals have been obtained, which provides a good condition for analyzing the composition of minerals and the basic properties of inorganic substances in coal. In the plasma environment, the surface modification behavior of different minerals is different. It can expand the difference of surface properties of different minerals and provide a new way for the separation of refractory minerals. The ozone produced by plasma has very strong activity and can react with organic chemicals in wastewater, which can effectively degrade the residues of organic chemicals in wastewater. And can be used in flotation, coal slurry treatment agent modification and so on, the application prospect is broad.
