Calcium carbonate (CaCO3), as a widely used compound, plays an important role in fields such as building materials, pharmaceuticals, food processing, and plastic filling.It mainly comes from three types of ores: calcite, marble, and limestone.Among these three types of calcium carbonate ores, calcite is the most stable, and due to its high purity and specific optical properties, calcite is suitable for high-end product manufacturing.

    Among these three types of calcium carbonate ores，calcite, marble, and limestone require targeted sorting strategies due to differences in particle size, shape, color, and internal impurities.Calcite and marble are sorted to remove discolored particles, while limestone needs to focus on removing impurities associated with the ore.Mingde Optoelectronics' photoelectric sorting equipment, such as color sorting machines and advanced AI ore sorting machines, will be able to "prescribe the right medicine".

    For example, marble type calcium carbonate enterprises in Guangxi have adopted Mingde Optoelectronics' color sorting machine, significantly improving the grade of the ore.In order to remove a certain amount of impurities, the limestone type calcium carbonate enterprise in Jiangxi Province has introduced the Mingde Optoelectronics AI ore sorting machine.

      The application of these devices has improved the sorting efficiency of ores and enhanced the competitiveness of enterprises. For example, in large mines, the dual screening process not only improves resource utilization but also reduces environmental pollution.

     In the future, new technologies will further enhance the overall level of China's calcium carbonate industry, promote efficient utilization and sustainable development of resources, and enhance the competitiveness of domestic enterprises in the international market.
