近日，中国地质科学院郑州矿产综合利用研究所研发的“一种从富锂铝土矿废石中提锂的方法” 获国家知识产权局授权，专利号为ZL202411547198.5。

该方法通过焙烧使富锂铝土矿废石中主要矿物如高岭石、蒙脱石、叶腊石等黏土矿物发生脱水反应，黏土矿物稳定的层状结构坍塌、分解，暴露、释放出层间吸附的锂，利用十二水硫酸铝钾或十二水硫酸铝铵作为浸出剂，可选择性浸出富锂铝土矿废石焙砂中锂，锂的浸出率可达85%，而废石中铝、铁等杂质浸出率仅5%，为后续溶液净化除杂带来巨大便利。浸出液冷藏结晶，固液分离后，晶体可用于配置浸出液，实现浸出剂循环利用。
该发明具有工艺简单、锂浸出率高、对设备要求低、浸出剂可循环利用、能耗低、提取成本低、浸出液杂质少、环境友好等优点，易于工业化应用，为富锂铝土矿废石及黏土型锂矿资源开发利用提供了一条新途径和新方法。

这是一个传统而不断焕新的行业。

矿产资源是经济社会发展的重要物质基础，矿业已成为全球经济不可或缺的重要力量。时至今日，矿业的基础性地位依然没有改变，并在加快经济社会全面绿色转型中扮演着关键角色。

当前，世界进入新的动荡变革期，全球经济复苏动能不足，全球矿业发展依然面临诸多挑战。

无疑，这一形势将进一步加速全球矿业格局的深刻变革，世界各地正同此冷暖。

面对严峻复杂的国际环境以及全球矿业供需格局的深化调整，构建矿业命运共同体、深入推进国际合作是当务之急。与人类经济社会发展深度交融的矿业，只有在全球范围可持续的交流合作中才能得以发展繁荣。让不同国家、不同阶层、不同人群都能从资源的可持续和绿色开发中受益，始终是发展矿业的终极目标。

历史经验也证明，世界上没有哪个国家能够完全依赖本国的矿产资源满足自身所有的需求。矿产资源分布与利用的不均衡性，决定了必须通过加强国际交流与合作，实现更广泛更深层次的能源资源互补与共赢。

多年来，我国矿业行业秉持互利共赢的原则，与世界很多国家在矿产资源勘查开发方面开展了卓有成效的合作，将绿色技术、绿色标准、绿色经验带到国外，把数字矿山、智能矿山、绿色矿山建到国外，有序推进新能源产业链合作，积极探索矿业高质量发展的共赢之路。与此同时，致力于形成开放稳定的国际矿产品市场，完善资源勘查开发合作机制，构建安全高效的矿产资源保障体系。

我们有理由相信，矿业领域这样的合作还将持续，并不断深入。本届大会推出多个高质量论坛、专场推介等环节，正是有意促成国家与地区之间、产业之间、产业内部之间的开放与合作，形成多方合作共赢及方式多元的发展模式。

如今的中国矿业，早已放弃不可持续的粗放式的发展模式，更加开放与现代，也更加理性与负责——注重数字技术的赋能、产业革新的裂变，注重资源安全与生态环境的统筹、矿山建设与绿水青山的协同。

事实上，当前中国经济增长展现出的强大韧性和向好态势，不仅为全球经济增长注入稳定力量，也让矿业经济信心回归的步伐更加坚定。2024年1-7月，我国采矿业固定资产投资同比增长19.3%，涨幅较年初扩大了4.9个百分点，明显高于2023年全年的2.1%，延续了良好的增长势头。

显然，这又是一个积极信号，对于推动中国矿业乃至全球矿业经济发展与繁荣具有重要的意义。

志合者，不以山海为远。让我们再一次紧紧相拥，于本次大会中预判不确定性中的确定性，摸准矿业生生不息的新脉动，捕捉矿业转型发展的新机遇，深化交流合作，共促矿业繁荣，为实现人与自然和谐共生的现代化、构建人类命运共同体贡献更多的矿业力量、矿业智慧、矿业方案。

We can see that the frontiers of development are being pushed to new heights. Over the course of this event, we will witness the launch of a comprehensive program that includes 1 theme forum, 5 high-level forums, 18 thematic forums, and 13 special promotions. New developments, trends, and directions in the mining industry will be shared and collided here. New theories, technologies, and methods in the mining industry will be exchanged and displayed here. New understanding, achievements, and experiences in the mining industry will be accumulated and presented here.

At this juncture, the world's attention is once again focused on China and the mining industry.

This is a traditional but continually evolving industry.

Mineral resources serve as a cornerstone for economic and social progress, and the mining industry stands firm as a vital and indispensable pillar within the global economy. To this day, The foundational role of mining remains unshaken, and it plays an important part in catalyzing a comprehensive green transformation of our economic and social landscapes.

In the present moment, the global economy is entering a new period of turbulence and change, and the current momentum of global economic recovery is insufficient. The development of the global mining industry still faces various challenges.

Undoubtedly, this complex situation will accelerate the profound shifts in the global mining dynamic, with the whole world facing similar challenges.

In light of the challenging and intricate international environment and the deepening realignment of the global mining supply and demand dynamics, it is crucial to foster a collaborative mining community and promote international cooperation. The mining industry, deeply intertwined with the economic and social development of humanity, can only flourish and develop through sustainable global exchanges and collaborative efforts. It has always been the ultimate goal of mining development to ensure that diverse nations, classes, and individuals benefit from sustainable and green resource development.

Historical evidence has demonstrated that no single country can rely solely on its own mineral resources to meet all its needs. The uneven distribution and utilization of mineral resources necessitate that a broader and more profound complementarity and win-win situation in energy resources be achieved through enhanced international dialogue and cooperation.

Over the years, China's mining industry, adhering to the principle of mutual benefit, has engaged in fruitful collaborations with numerous countries worldwide in the exploration and development of mineral resources, introduced green technologies, standards, and experiences abroad, built digital, intelligent, and green mines abroad, promoted the cooperation of the new energy industry chain in an orderly manner, and actively explored the win-win solution of high-quality development in mining industry. At the same time, we are committed to forming an open and stable international mineral market, improving the cooperation mechanism for resource exploration and development, and constructing a safe and efficient mineral resources guarantee system.

We are confident that such collaborative efforts in the mining sector will persist and intensify. This year's conference, with its array of high-quality forums and special promotions, aims to contribute to the opening up and cooperation between countries and regions, inter-industries, and intra-industries, fostering a multi-party win-win solution and a diversified development model.

Today, China's mining industry has long abandoned its unsustainable and rudimentary development model, evolving to be more open, modern, rational, and responsible. The initiative prioritizes the advancement of digital technology and the acceleration of industrial innovation, the integration of resource security with ecological environments, and the collaborative development of mine construction with the protection of lucid waters and green mountains.

In fact, the strong resilience and positive trends currently demonstrated by China's economic growth not only provide a stabilizing force for global economic advancement but also reinforce confidence in the mining economy's recovery. From January to July 2024, China's investment in the mining industry's fixed assets increased by 19.3% year-on-year, which is a 4.9% rise compared to the beginning of the year and significantly higher than the 2.1% growth for the full year of 2023, thus maintaining a strong growth trajectory.

This is undoubtedly another positive signal, which is of great significance for promoting the development and prosperity of China's mining industry and, by extension, the global mining economy.

Those who share the same vision are not separated by mountains and oceans. Let us once again embrace each other tightly, foresee the uncertainties within the certainties, feel the new pulse of the mining industry, seize the new opportunities for its transformation and development, deepen cooperation and communication, promote mining prosperity together, strive for the modernization of harmonious coexistence between humanity and nature, and contribute to building a community of shared destiny, offering more mining power, wisdom, and solutions in this conference.

Let us use this conference as a point of reference to plant the seeds of hope, and embark on a journey towards a promising future for the mining industry and for humanity as a whole!
