Development Status and Prospect of Chinas Calcium Carbonate Industry

As a branch of the non-metallic mineral industry, calcium carbonate industry is developing rapidly in my country, and dolomite manufacturers have become an important industry in the non-metallic mineral industry. According to the statistics of the Calcium Carbonate Special Committee of the China Non-Mining Association, there are currently nearly 1,000 calcium carbonate production and processing enterprises in my country, including more than 400 heavy calcium carbonate enterprises with a certain scale, more than 320 light calcium carbonate enterprises, and the price of dolomite sand is higher than The total production capacity is about 7 million tons (including about 4 million tons of heavy calcium and about 3 million tons of light calcium). Judging from the more than 150 production enterprises surveyed and analyzed by the association, about 4% have an annual production scale of more than 50,000 tons, 10% have an annual production scale of 20,000 to 50,000 tons, and an annual production scale of 10,000 to 20,000 tons. 26% of them are 10,000 tons, and the other 60% of the enterprises have a production scale of less than 10,000 tons. Although the development and production of calcium carbonate products in my country started relatively late, it has developed rapidly. In 1992, the output of heavy calcium was only 370,000 tons, and by 2002, it was nearly 5.2 million tons, with an average annual growth rate of about 32%. Dolomite sand manufacturers

From the perspective of product structure, calcium carbonate production particle size is 200 ~ 325 mesh products accounted for 50%; 325 mesh ~ 10μm products accounted for about 35%; products above 10μm accounted for 15%. Among them, the surface-treated active heavy calcium products accounted for 12%. At the same time, my country's research on nano-scale calcium carbonate and its industrial application has received high attention, and the pace of industrialization has been accelerated, and industrial-scale production enterprises have been established.
