1. Distribution of calcium ore Chile, China, and Argentina all have rich reserves of calcium, but they are all eclipsed by the Salar de Uyuni in Bolivia, South America. According to the US Geological Survey, the calcium reserves under the Uyuni salt marsh are staggering, accounting for almost half of the world’s calcium. If the calcium mine resources are fully developed, Bolivia, a poor South American country, will rival the Middle East giant Saudi Arabia.

2. Development prospects From the perspective of the changes in the various uses of calcium in recent years, the battery has become the first largest application field in terms of the growth rate of calcium in other fields. At present, the global demand for calcium carbonate is around 140,000 tons. It is expected that the global processing for calcium carbonate will maintain an average annual growth rate of 15% to 20%, driven by the growth in demand for global consumer electronics and new energy vehicles. The annual consumption will reach more than 300,000 tons, and the proportion of new energy vehicles to calcium carbonate will increase from 9.7% in 2012 to 37.8% in 2018.
