Abstract

Graphite-based materials have attracted extensive attention due to their structure and excellent conductivity. Thus, the graphite-based ore industry has developed quickly. However, a complete industrial chain from raw materials, research and development (R & D), various types of applications, and commercial products have not yet been fully formed. To further accelerate the process of industrialization, optimizing the beneficiation process is necessary for improving the valuable minerals because of the difference in physical and chemical properties of the mineral. This review briefly introduces the standard beneficiation methods: gravity, magnetic, electric, and flotation separation. Specifically, we present a comprehensive process of the flotation method, including developing flotation reagents (collecting agent, foaming agent, inhibitor, activation agent, and pH regulators) and the revolutionary process of high-quality graphite flake. Finally, the representative energy storage application, including supercapacitors and batteries utilizing graphite-based materials, was discussed in the aspect of filtering alternating current, flexible, stretchable, transparent, and high-performance energy-storage devices. This review not only summarizes the high-quality graphite obtained from the graphite ore flotation method but also encourages graphite-based materials research and development in academia and industry, which has the potential to directly affect the industrialization process by lowering the manufacturing cost of post-treatment graphite.

石墨矿浮选储能应用前景综述

石墨基材料以其优良的结构和导电性引起了广泛的关注。因此，石墨基矿石工业得到了迅速发展。然而，从原材料、研发(R &D)，各种类型的应用，商业产品尚未完全形成。为了进一步加快工业化进程，对选矿工艺进行优化是提高选矿价值的必要条件，因为选矿物的理化性质存在差异。本文简要介绍了重选、磁选、电选和浮选等标准选矿方法。具体来说，我们介绍了浮选方法的综合过程，包括浮选试剂(捕收剂、起泡剂、抑制剂、活化剂和pH调节剂)的开发和高质量石墨薄片的革命性过程。最后，从滤波交流电、柔性、可拉伸、透明、高性能的储能器件等方面讨论了石墨基材料的储能应用，包括超级电容器和电池。本文对石墨矿浮选法获得的高质量石墨进行了总结，鼓励学术界和工业界对石墨基材料进行研究和开发，降低后处理石墨的制造成本，有可能直接影响到产业化进程。

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
