As a large talc resource country, China's talc industry has experienced decades of development history. With abundant resources and relatively low prices, it has certain advantages in both domestic and international markets. In recent years, with the development of the economy, there have been higher requirements on the quality and price of talc products. How to make the advantages of the past continue, further strengthening their own management and actively participating in international competition are two indispensable factors.
Talc is one of China's dominant minerals and is known for its abundant resources and high quality. According to statistics, the reserves of 38 mines nationwide are 250 million tons, and both proven reserves and retained reserves rank second in the world. China's talc deposits are widely distributed in 15 provinces and autonomous regions, but they are relatively concentrated in the five provinces (regions) of Liaoning, Shandong, Guangxi, Jiangxi, and Qinghai. The sum of reserves accounts for 95% of the total resources of the country. There are 24 deposits in the five provinces (districts). According to the scale of China's talc deposit size: deposits of ≥10 million tons are extra large, 10-5 million tons are large, 500-100 is medium-sized, and less than 1 million tons is small. The five provinces (districts) have five extra-large deposits, three large deposits, nine medium-sized deposits and seven small deposits.

Current status of talc production and processing technology
China's talcum powder processing mainly uses dry processing. The equipment used is mainly Raymond machine, mechanical impact pulverizer and airflow mill. Various ball mills and other mills are used less. In the 1980s, the processing equipment for talcum powder was mainly the traditional Raymond machine; from the late 1980s to the 1990s, the Japanese Hosokawa MNC502 superfine mill was introduced and the CIM51 superfine grinder developed on this basis; From the late period to the end of 2000, the use of jet mills made with German core technology has been widely used. At present, Chinese talc manufacturers have mature technology and ability to produce talc powder of 45μm-5μm or even finer. Activation, modification and granulation technologies are gradually being applied. Nano talc products have been jointly developed by universities and manufacturers.
Domestic market demand is growing rapidly
In recent years, there have been noticeable changes in the domestic market. In the past, the domestic market was dominated by low-end products and used in low-end markets such as paper-making fillers. These markets have shrunk rapidly since 2000. In contrast, mid- to high-end products for plastics, coatings, and cosmetics have grown rapidly in recent years. It is worth noting that China's annual import of talc has exceeded 20,000 tons. Even in the global financial crisis in 2009, the number and price of imported talc has not decreased significantly compared with 2008, which is the overall decline of the world economy. A sharp contrast.
In the next few years, domestic demand for medium and high-grade talc will maintain a relatively fast growth rate. If the development of the talc industry in the past 30 years is mainly from the export market, then the demand in the domestic market will exceed the export. In 2010, China's production of paper, paint, automobiles, home appliances and ceramics reached the top in the world, and these markets are the main areas of talc, and the market potential is huge. The Yangtze River Delta and the Pearl River Delta are the most important consumption areas. The main market growth in the future is in plastics, especially PP plastics, which are used in the automotive industry, home appliances and packaging products, and the annual growth rate will remain at 5-10%.
The international market still imports Chinese talc as the main source
The demand for talc in China in the international market is particularly reflected in the white talc. The demand for Chinese white talc in the world market is still growing, and China's talc will remain an irreplaceable source of the world market, especially in the Asian market. 95% of the talc imported from Japan and South Korea comes from China. The supply of white talc in the world is unlikely to change in the future, and the main source remains China.
The only way to perfect and transcend
China's talc industry should learn from foreign advanced technology and experience on the road of perfection and transcendence, but it is necessary to strengthen its own management and technology.
From the reference, we can see that European multinational companies such as Luznak, Omega, and Yimifabi are leading the world in talc processing technology. These companies' talc processing technology and technology truly represent scale and automation. Modern production features. Therefore, we must learn the advanced product research and development capabilities of advanced countries, the ability to open up the international market, and the application level of new technologies and technologies. Of course, strengthening international exchanges and cooperation can also promote the overall level of China's talc industry.
To strengthen their own management and technology improvement, we must realize that the further development of the talc industry can no longer rely on cheap resources, and must rely on the processing and technological advantages accumulated over the years to develop high value-added deep processing products and improve resources. Effective use. Specifically embodied in the following aspects:
Regulate the export of raw materials and encourage the export of manufactured goods. For many years, China's talc exports use the same quota regardless of raw materials, primary products or deep processing high value-added products. At the end of 2008, the state imposed an export tariff of 5% to 10% on all products including high value-added. The adverse effects of raw material shortages on the processing industry have already emerged, and the proportion of powder exports has not increased significantly over the years. On the other hand, raw materials are still exported in large quantities, and we have to reflect on the policy issues. Different quota management and tariff policies are applied to the export of raw materials and powders to encourage the export of manufactured goods.
Encourage the development and utilization of medium and low-grade raw materials. The use of low- to medium-grade raw materials is mainly the use of talc mixtures. The talc mixture is a waste mixture after beneficiation with a talc content of 30% to 70%. The domestic market cannot fully digest the talc mixture, and exports have always been an important market.
Allows infeed processing and utilizes global resources. From a long-term perspective, abundant raw materials and processing capacity are the two cornerstones for the further development of China's talc industry, and they are indispensable. We must not only consider how to effectively use our resources, but also look at the world and consider the use of global resources for me.
