Main production products
At present, China has produced and developed in the west of the graphite minerals (including mineral processing, chemical purification products) and graphite products two categories, a number of products.
1. Mineral processing
Graphite processing plant Chemical purification Products: according to the different production methods and fixed carbon content, natural flake graphite is divided into high-purity graphite, high carbon graphite, medium carbon graphite, low carbon graphite four kinds.
2. Graphite Products
China produces more varieties of graphite products, according to its production process and use of different, mainly colloidal graphite, expandable graphite and its products, carbon graphite products and graphite crucible and other deep-processing products.
China’s main state-owned graphite processing enterprises are currently more than 40, other types of economic type graphite electrode mining enterprises have more than 100, generally small. 1996 China’s total graphite production capacity of about 2 million t.
In addition, at present, China has more than 100 graphite processing products enterprises, its total production capacity of about hundreds of thousands of tons of processed products.
According to the China National Building Materials Bureau statistical Report, 1996 China’s graphite production of 1950515t, including the crystalline graphite 588165t (including the sale of coarse concentrate production).
China’s crystalline graphite is mainly concentrated in Shandong, Heilongjiang, Inner Mongolia, Hubei and other provinces. In 1996 years, the production of crystalline graphite in four provinces accounted for 98.8% of the total production of crystalline graphite in China, and the hidden crystalline graphite was mainly concentrated in Hunan, Jilin and Shaanxi provinces. In 1996 years, the production of invisible crystalline graphite in three provinces accounted for 68.53% of the total production of Chinese hidden crystalline graphite.
According to mineral commodity summaries 1996 data, 1996 China SGL Graphite Supply production ranked 1th in the world, followed by South Korea, India, other major producers and Mexico, Brazil and so on. Canadian graphite production has grown faster in recent years and is likely to become the world’s leading producer of graphite. Some of the potential graphite producing countries are: Tanzania, Australia, Namibia, Mozambique, Sweden, Egypt, etc.
With the expansion of application fields and the growth of demand, China’s graphite production rose from 160,000 T in 1980 to 680,000 T in 1990, an average annual increment of 15.57%. However, after entering the 90 ‘s, graphite production once fell, 1992 to 508,000 T, after a year of recovery, 1994 began to show a big development trend, the 1996 China graphite production amounted to 1.95 million t, twice times more than 1993, is the highest production since the 90 generation. China’s graphite production accounted for more than half of the world’s output. In addition, China in the graphite raw materials and graphite products production and processing also has a considerable development, now not only the production of primary raw materials, but also to produce color kinescope graphite milk, GRT energy-saving additive products. At present, some of the graphite products produced in China have entered the international market, and the new application field is expanding continuously.
