As of 2024, China's calcium carbonate demand and growth show the following characteristics:

Demand continues to rise: According to China Powder Network, from 2014 to 2023, the global calcium carbonate industry demand increased from 103 million tons to 141 million tons, with a compound annual growth rate of 3.54%. China's calcium carbonate production increased from 30 million tons in 2016 to 67 million tons in 2023, with an annual compound growth rate of more than 10%. This shows that the demand for calcium carbonate in China continues to rise.

Main application areas: Calcium carbonate is widely used in plastics, papermaking, coatings, rubber and other industries. Among them, plastics and papermaking industries are the largest application areas of calcium carbonate, accounting for about 31% and 30% respectively. The coating industry accounts for about 13%, the rubber (adhesive) industry accounts for about 12%, and other fields such as building materials, food, and medicine account for about 3%.

Import and export situation:

Import: In September 2024, China's calcium carbonate imports were 14,200 tons, up 61.36% month-on-month and 82.05% year-on-year. Imports from January to September were 109,300 tons, up 58.68% from the same period last year.

Exports: In September 2024, China's calcium carbonate exports were 10,200 tons, down 3.77% from the previous month and 9.73% from the same period last year. Exports from January to September were 100,200 tons, up 9.63% from the same period last year.

Future growth forecast:

Market potential: With the gradual boost of China's economy and manufacturing industry, the calcium carbonate industry is expected to usher in a new round of development cycle.

Technological innovation: In the next few years, the calcium carbonate industry will rely more on technological innovation to promote the industry to develop in the direction of high-end, large-scale, intensive, low-energy consumption and low-emission.

Environmental protection policy: The tightening of environmental protection policies will prompt enterprises to increase technological transformation and equipment renewal, improve resource utilization efficiency and reduce environmental pollution.

Nano calcium carbonate: As a high-end product, the market demand for nano calcium carbonate is growing rapidly. It is expected that the demand for nano calcium carbonate will increase by about 20% annually in the next few years. With the improvement of product quality and the reduction of costs, the market competitiveness of domestic nano calcium carbonate will be further enhanced.

In summary, the demand for calcium carbonate in China will continue to grow in 2025, especially in traditional application areas such as plastics, papermaking, coatings, and high-end markets such as nano calcium carbonate. In the next few years, with the promotion of technological innovation and environmental protection policies, the calcium carbonate industry will usher in new development opportunities.

In order to meet the diversified needs of the development of the calcium carbonate market, MINGDER has launched various types of ore color sorters and artificial intelligence sorters, which can efficiently sort and process calcium carbonate with different quality requirements. The following are some specific applications and technical features of MINGDER in the field of calcium carbonate sorting:

MINGDER ore color sorter

Heavy-duty color sorter

Application scenario: Mainly used for sorting large-particle calcium carbonate ore (3-8 cm), reducing the loss of powder ore during the crushing process, and increasing sorting capacity.

Technical features: Using advanced color recognition technology, it can accurately sort out heterochromatic associated gangue, with a net selection rate of more than 99%.

Output: The output of a single device can reach 40-50 tons/hour.

Economic benefits: After removing the costs of site, equipment, loss, electricity and other expenses, the economic benefits per ton increase by 30-50 yuan.

Double-layer ore color sorter

Application scenario: Suitable for complex ores (ores with high impurities) that require multiple sorting.

Technical features: The double-layer design can be used for compound sorting at one time, with the upper layer throwing waste stone and the lower layer carefully sorting concentrate and associated ores, and finally selecting high-quality calcium carbonate.

Advantages: Easy operation, convenient maintenance, excellent sorting effect, and can significantly improve the quality and market competitiveness of calcium carbonate.

Artificial intelligence sorting machine

Application scenario: Suitable for whitening and sorting of calcium carbonate, as well as removal of impurities.

Technical features: It adopts process flows such as crushing, screening, washing and sorting, and can process calcium carbonate ores of various particle sizes. The output of a single device ranges from more than ten tons to dozens of tons per hour.

Application range: Widely used in the sorting of various ores such as calcium carbonate, quartz, limestone, fluorite, and barite.

Heavy-duty artificial intelligence ore sorting machine

Application scenario: Suitable for the sorting of large-particle calcium carbonate and other ores.

Technical features: Adopting the latest artificial intelligence sorting technology, it has a wide sorting range and high precision, and can effectively identify and sort out ores of different colors and textures.

Advantages: The missorting rate can be greatly reduced during the sorting process, and the sorting processing capacity can be increased. The equipment structure is durable, wear-resistant, and impact-resistant, and is suitable for long-term high-frequency use.

The ore color sorter and artificial intelligence sorter launched by MINGDER Company can meet the requirements of calcium carbonate sorting with different quality requirements, improve sorting efficiency and product quality, and bring significant economic benefits to mining companies. Whether it is the sorting of large-particle calcium carbonate ore or the production of high-value-added calcium carbonate, MINGDER's equipment can provide reliable solutions.
