Specification :

¡¡¡¡China is a large producer also a large consumer of calcium carbonate. With the development of light industry, the demand for calcium carbonate is increasing. Influenced by the resource distribution such as mineral, coal and electric power, calcium carbonate production is over demand in North China, while in South China, northeast and Yangtze - Huaihe River region, it is in short supply. In recent years, the production of heavy calcium carbonate is developing fairly fast in China.

¡¡¡¡In 2002, total demand for calcium in China was 5.67 million tons, and in 2005, it has increased to 10.41 million tons. In 2007, the figure was 13.49 million tons, up by 14.2% year on year, and the demand is expected to reach as many as 14.98 tons for the whole year of 2008, , up by 11.05% year on year.

¡¡¡¡In 2007, calcium carbonate consumed by plastic, paper making, coating, and rubber industry was 4.8 million tons, 3.37 million tons, 1.99 million tons, and 0.89 million tons respectively, accounting for 35.6%, 25%, 14.8% and 6.6% of the total consumption respectively.
