About JinhuiEstablished in 1999, the company is located in Pingdu City, Qingdao, Shandong Province, a prime production area for high-quality flake graphite in China.
Flake graphite is extracted from graphite mines and obtained through processing. As the extracted ore types vary, the processing of flake graphite must also be done correctly according to the characteristics of the graphite ore. So, how should this be operated? Below, let's have a brief understanding of flake graphite.

Graphite Purification Methods (Part 1)
Flotation is a conventional mineral purification method characterized by lower energy and reagent consumption and reduced costs. This represents a significant advantage for graphite purification using flotation. However, when employing flotation for graphite purification, the improvement in graphite grade is limited.

Graphite Purification Methods (Part 2)
The main advantages of the hydrofluoric acid method are high impurity removal efficiency, high purity of the obtained product, minimal impact on the performance of graphite products, and low energy consumption. The disadvantages are that hydrofluoric acid is highly toxic and strongly corrosive, requiring strict safety precautions during the production process, and the strict equipment requirements also lead to increased costs. Additionally, the wastewater generated by the hydrofluoric acid method is highly toxic and corrosive, requiring strict treatment before discharge, and environmental investment significantly offsets the advantage of its low cost.

近年来，各种类型的低密度碳石墨材料得到了积极的研究，其中典型的包括由中间相沥青或聚合物树脂制成的碳(石墨)泡沫，以及用高重复率脉冲激光烧蚀碳材料时形成的碳纳米泡沫。膨化石墨也是一种低密度碳石墨材料。由于膨化石墨制备工艺简单，生产成本低，便于大规模工业化生产，近年来对可膨胀石墨的研究仍在不断深入。以下金汇石墨公司的小编介绍了将柔性石墨浸泡在浓酸中制成低密度膨化石墨块的方法：
