Among them, compared with heavy calcium carbonate, light calcium carbonate has the advantages of small bulk density, high oil absorption value, regular particle shape, large specific surface area, large sedimentation volume, and high dry coverage. It is mainly used in rubber, plastic, paper, paint, etc.， water-based coatings, papermaking, building materials, food, medicine and other fields.
At this stage, China is one of the countries with the richest limestone resources in the world. Limestone is the main raw material of light calcium carbonate. The sufficient supply of upstream raw materials has laid a good foundation for the development of light calcium carbonate industry. In recent years, under the background of sufficient domestic supply of light calcium carbonate raw materials and increasing demand in the application market, its market size has continued to expand.
The market size of China’s light calcium carbonate has grown from 9.15 billion yuan in 2017 to 12.78 billion yuan in 2021, with a compound annual growth rate of 6.91%. At present, light calcium carbonate is the mainstream product in the calcium carbonate market, and its scale will account for 55% of the total domestic calcium carbonate in 2021. In 2021, the domestic output of light calcium carbonate will be 14.521 million tons, a year-on-year increase of 3.2%.
There are a large number of light calcium carbonate enterprises in China, but most of them are small and medium-sized enterprises, and the industry concentration is low. In the future, with the continuous development of domestic high-tech industries such as automobiles and aerospace, driven by the growth in demand for high-end coatings and new sealing materials, the domestic market demand for high-end light calcium carbonate will continue to increase. Therefore, in the future, local enterprises need to continuously improve production technology and product diversification, and promote the continuous development of light calcium carbonate products towards ultra-fine and high-purification trends. In the future, the domestic industry concentration is expected to continue to rise, and the industry has great potential for development.
At the same time, light calcium carbonate is a resource-constrained industry, which is distributed in various provinces and cities, resulting in a relatively scattered enterprise layout. In recent years, under the background of continuous strengthening of domestic environmental protection, the focus of domestic light calcium carbonate production has gradually shifted from the eastern region to the central and western regions, the trend of industrial agglomeration has been highlighted, and the industry has broad prospects for development.
