As a major producer and consumer of calcium carbonate globally, China accounts for over 50% of the world's total production and consumption of light calcium carbonate, and over 25% of the world's total production of heavy calcium carbonate. Data shows that in 2022, China's calcium carbonate industry had a production capacity of approximately 44.2 million tons, a year-on-year increase of 2.2%; the output was approximately 36.85 million tons, a year-on-year increase of 3.8%; and the demand was approximately 36.815 million tons, a year-on-year increase of 3.8%.

I. Overview

Guangxi Longhua Calcium carbonate is an inorganic compound with the chemical formula CaCO₃, and is the main component of limestone, marble, etc. Calcium carbonate is usually a white crystal, odorless, and essentially insoluble in water. It readily reacts with acids to release carbon dioxide. It is one of the most common substances on Earth, found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine, and is also a major component of the skeletons or shells of some animals. Calcium carbonate is also an important building material with widespread industrial applications.

According to the different production methods of calcium carbonate in Guangdong, calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate, and crystalline calcium carbonate; according to the size of the average particle size (d) of calcium carbonate powder, it can be divided into micro-calcium carbonate (d＞5m), fine calcium carbonate (1m), and ultrafine calcium carbonate (0.02m); according to whether the arrangement of atoms and ions constituting calcium carbonate is regular, calcium carbonate can be divided into crystalline calcium carbonate and amorphous calcium carbonate.

II. Industry Policies

Guangxi Longhua As an important part of the non-metallic industry, China's calcium carbonate industry is currently in a development stage. In recent years, relevant government departments have successively introduced relevant policies and measures to support the development of the non-metallic and calcium carbonate industries. For example, the "5G Application "Setting Sail" Action Plan (2021-2023)" released in 2021 promotes the application of 5G in various mining areas such as energy minerals, metal minerals, and non-metallic minerals, expands 5G application scenarios such as remote control and unmanned driving in the mining industry, and promotes remote control and cluster operation of core mining equipment underground, unmanned operation of mining equipment in deep high-risk areas, and intelligent continuous operation and unmanned transportation in open-pit mines.
