摘要

氧化纳米材料对浮选过程的影响。全球水资源形势的重大挑战主要是由世界人口增长和气候变化引起的，需要新颖的创新水技术，以确保饮用水的供应并减少全球水污染。为此目的，高度先进的纳米技术为先进的水和废水技术过程的技术发展提供了新的机会。本文介绍了一种用于废水处理和矿物分离的重要方法——浮选。并介绍了影响泡沫浮选过程的因素，如纳米颗粒的疏水性、纳米颗粒的直径、颗粒的柔软度等。关键词:纳米材料，浮选工艺，泡沫浮选，疏水性，纳米粒径，气泡大小

EFFECTS OF OXIDE NANOMATERIALS USED IN FLOTATION PROCESS IN WASTEWATER TREATMENT

– Effects of oxide nanomaterials used in flotation process. Important challenges in the global water situation, mainly resulting from worldwide population growth and climate change, require novel innovative water technologies in order to ensure a supply of drinking water and reduce global water pollution. For this purpose, highly advanced nanotechnology offers new opportunities in technological developments for advanced water and wastewater technology processes. This paper presents an important method used in the wastewater treatment and in the mineral separation, named the flotation. Also, this paper presents the factors that influence the froth flotation process, such as: nanoparticle hydrophobicity, nanoparticle diameter, particle softness etc. Key-words: nanomaterials, flotation process, froth flotation, hydrophobicity, nanoparticle diameter, bubble size
