关于召开首届世界钙业大会的邀请函 the First World Calcium Industry Conference
致全球钙企业及专家学者/To global calcium enterprises and experts and scholars：
2025 年，全球碳酸钙将突破 1.2 亿吨，主要钢铁、合金、建筑和环保领域。从碳酸钙矿到粉体材料，由钙粉脱硫剂到副产石膏，再到（氢）氧化钙、纳米钙、金属钙、铝酸钙、钛酸钙、高纯钙、钙合金以及钙复合线，乃至可降解型硫酸钙晶须与食药钙剂等诸多品类，无一不是朝着高质生产力发展迈进。中国早在公元前 7 世纪开始使用石灰，商周时期青铜铸造已系统应用生石灰作为助熔剂。学习和借鉴国际化矿山开采、破碎、焙烧、锻白和球磨先进经验，了解和掌握钙及相关产业应用前沿技术工艺，取长补短、跨界融合，提高钙高附加值和全球化竞争力，是世界钙业面临的市场机遇。
By 2025, the global calcium carbonate market is expected to exceed 120 million tons,mainly in the fields of steel, alloys, construction and environmental protection. From calcium carbonate ore to powder materials, from calcium powder desulfurizer to by-product gypsum, and then to calcium oxide (hydroxide) , nano-calcium, metallic calcium, calcium aluminate, calcium titanate, high-purity calcium, calcium alloys and calcium composite
lines, as well as degradable calcium sulfate whiskers and food and medicine calcium supplements and many other categories, all are advancing towards high-quality productivity.Lime was first used in China as early as the 7th century BC. During the Shang and Zhou Dynasties, quicklime was systematically applied as a flux in bronze casting. Learning from and drawing on the advanced experience of international mining, crushing, calcination,
bleaching and ball milling, understanding and mastering the cutting-edge technologies and processes of calcium and related industries, complementing each other's strengths,cross-border integration, and enhancing the high added value and global competitiveness of calcium are the market opportunities faced by the world's calcium industry.
因此，决定于 2025 年 12 月 3 日～5 日在珠海召开“首届世界钙业大会”。现将具体事项说明如下。
So, it has been decided to hold the "First World Calcium Industry Conference" in Zhuhai from December 2nd to 5th, 2025. The specific matters are hereby explained as follows.
