Why does China still need to import kaolin

Release time:2020-10-26 14:30:03  Number of views:

China's kaolin mineral resources have the following characteristics: a small number of large-scale mineral deposits; The types of mineralization are relatively chaotic; There are many accompanying minerals with poor quality. Kaolin was developed and used earlier in China, traditionally used for ceramics and refractory materials. Since the 1980s, it has been widely developed and used, and its application fields have gradually expanded. In recent years, the development and utilization of kaolin mineral resources in China have increased rapidly. Under the guidance of the mindset of emphasizing economic benefits over comprehensive use in some regions, blind excavation, blind investment, blind production, and blind sales have emerged. For example, some kaolin is suitable for making ceramic clay, but developers, regardless of the quality indicators of ore resources, are enthusiastic about advanced products such as paper making kaolin and industrial filler grade kaolin. As a result, only 1 ton of concentrate product can be selected from 5 or 10 tons of raw ore, and the rest can be discarded as tailings, resulting in huge waste of mineral resources. To ensure the supply of mineral resources, we need to rely on both open source and cost reduction. Open source requires increasing geological exploration efforts and finding more new resources; Throttling is to maximize the use of existing resources and activate idle resources. The key to revitalizing idle resources, utilizing existing resources reasonably, and improving resource assurance lies in strengthening the comprehensive use of mineral resources.

Canada, the United States, has large reserves of kaolin and low sand content. The products processed are suitable for industries such as papermaking in China, so imported kaolin is also suitable for high-end industries
