Research Status of Resource Utilization of Graphite Tailings
-
摘要:
这是一篇矿业工程领域的论文。石墨作为一种无机非金属材料在我国应用十分广泛,而且在化工、电气等行业中也占有重要地位,同时在国防、高技术领域有着不可取代的地位。然而,由于石墨矿开采的同时会伴随遗留大量尾矿,不但占用了大量的土地,而且对生态环境造成了严重的污染。本文通过查阅大量文献资料,对目前石墨尾矿资源化利用研究现状进行归纳,对石墨尾矿大量堆积问题进行了探讨,提出了有助于其资源化利用的建议。
Abstract:This is an article in the field of mining engineering. Graphite is an inorganic nonmetallic material widely used in China, and it also plays an important role in chemical industry, electrical industry, national defense and high-tech fields. Graphite mining will produce a large number of tailings, it not only occupies a lot of land but also causes serious pollution to the ecological environment. By consulting a large number of documents, the current research status of graphite tailings resource utilization is summarized in this paper, and the problem of massive accumulation of graphite tailings is discussed, and some suggestions are put forward to help its resource utilization.
