节约集约的山东实践|日照莒县:矿坑地上长出新“良田”
Qi Lu Wan Bao· 2025-09-07 12:00
记者 张阿凤 从空中俯瞰沭河流域历史遗留废弃矿山生态修复项目,曾经废弃矿山集中连片、矿石废渣纵横遍布、地形地貌支离破碎的土地正悄然发生着蝶变,一条生机 盎然的葱茏绿带正在眼前铺展开来。 作为山东省矿产资源大县,莒县已发现矿种38种,占全省已发现矿种的25.7%。自上世纪六七十年代群众"自采自用"到八九十年代"个体私营",遍地开花的 小型采矿企业曾推动莒县经济发展,也给资源管理带来巨大挑战。 2023年,莒县被自然资源部认定为首批自然资源节约集约示范县。这座有着悠久采矿历史的县城,如何实现从"粗放开采"到"精细利用"的转型?记者近日走 进莒县,探寻其矿产资源节约集约利用的创新实践。 修复与重生 从"生态伤疤"到"希望田野" 站在莒县长岭镇沭河流域生态修复项目现场,很难想象这片绿意盎然的耕地与林地,曾是连片废弃矿坑。 "两年前这里还是一片坑坑洼洼、寸草不生的荒山野岭,你看现在,一眼望不到头的平整土地,玉米长得多带劲,多亏旁边的蓄水池,今年大旱都没渴着地 里的苗。"附近村民王老伯感叹。 "过去这里开了数十家砖瓦窑厂,停止开采后,这片土地也不能种地,只能放牧,还经常有石头从上面掉下来,很危险。"莒县城市建设投资集团有 ...
我国科研人员围绕月表水演化有新发现
Huan Qiu Wang Zi Xun· 2025-08-27 14:48
该发现不仅为解释遥感观测中月球富钛区域水的显著日变化现象提供了可能的矿物学机制,同时也为未 来以钛铁矿为主要对象的月球原位资源开发提供了重要科学依据。相关研究成果近日在国际学术期刊 《自然—通讯》发表。 中国科学院国家空间科学中心与中国科学院地质与地球物理研究所联合团队对申请到的嫦娥五号月壤中 的钛铁矿颗粒开展了水含量和H同位素的分析,并对其风化层的微观结构进行了研究。 该研究首次阐明了钛铁矿月壤颗粒在月表水的分布和储存中扮演的双重作用。一方面,钛铁矿能够通过 与太阳风的高效相互作用,促进太阳风H向水的转化;另一方面,受其晶体结构特性限制,钛铁矿风化 层中生成的水难以长期稳定保存。 来源:央视新闻客户端 探明月表水的分布与储存机制,是理解月表物质演化、资源分布乃至未来利用的基石。遥感光谱观测和 月壤样品分析均表明,太阳风注入的氢(H)是月表水的一个重要来源。 △钛铁矿颗粒太空风化层的微观结构特征 (总台央视记者 帅俊全 褚尔嘉) ...
海外季报:2025Q2,公司锆、金红石、合成金红石合计产量同比增加5%至14.97万吨,合计销量同比减少3%至13.27万吨

Investment Rating - The report recommends a "Buy" rating for the industry, predicting that the industry index will outperform the Shanghai Composite Index by 10% or more in the upcoming period [5]. Core Insights - The total production of zircon, rutile, and synthetic rutile increased by 5% year-on-year to 149,700 tons in Q2 2025, while total sales decreased by 3% year-on-year to 132,700 tons [1]. - The production of zircon sand was 36,900 tons, a 6% increase quarter-on-quarter but a 21% decrease year-on-year. Zircon concentrate (ZIC) production saw a significant increase of 129% quarter-on-quarter and 186% year-on-year, primarily due to sales recognition in the current quarter [1][2]. - Rutile production decreased by 40% quarter-on-quarter and 43% year-on-year, while synthetic rutile production increased by 4% quarter-on-quarter and remained nearly flat year-on-year [1][2]. - The average realized price for zircon sand was $1,692 per ton, consistent with the previous quarter and expectations. The average realized price for synthetic rutile was $1,147 per ton, slightly higher than the first quarter, while rutile's price decreased by approximately 3% to $1,496 per ton [3]. Production and Sales Summary - In Q2 2025, the total production of zircon/rutile/synthetic rutile (Z/R/SR) was 149,700 tons, a 15% increase quarter-on-quarter and a 5% increase year-on-year [1]. - The total sales volume for Z/R/SR was 132,700 tons, a 14% increase quarter-on-quarter but a 3% decrease year-on-year [2]. - The total revenue from Z/R/SR was 280 million AUD, a 16% increase quarter-on-quarter but an 11% decrease year-on-year [7]. Project Updates - The Eneabba rare earth refinery project is progressing, with an internal rate of return (IRR) projected between 35% and 51% under various scenarios. The refinery is expected to be one of the few outside China capable of processing multiple raw materials and producing both light and heavy rare earth oxides [8]. - The Balranald project in New South Wales is advancing as planned, with underground mining technology being implemented. The project is on track for commissioning in the second half of 2025 [11]. - The Wimmera project in Victoria is undergoing a definitive feasibility study (DFS) with a focus on rare earth reserves, and environmental impact assessments are in progress [12].
喀麦隆:政府设立谈判机构以保障矿业项目中的国家利益
Shang Wu Bu Wang Zhan· 2025-06-20 15:18
政府希望该机构能够维护国家在签署的采矿协议中的经济和社会利益(通过谈判获得对国家有利的 费率),并确保采矿项目的可行性和盈利能力。此外,框架还应确保采矿协议符合《采矿法》规定和相 关现行法律法规,以及在采矿项目中保障本国公民的最佳就业条件和环境保护。建立该谈判框架将有助 于最大化该行业收入并实现经济转型。根据世行数据,2023年采矿业占该国国内生产总值的25.2%,主 要由石油和天然气开采驱动。法国对外贸易保险公司估计,石油以外的采矿活动(铁、铝土矿、钴等) 占不到4%,这表明采矿潜力尚未得到充分开发。 矿业协议谈判框架的建立是在喀麦隆更新2023年矿业法后,试图吸引投资者开发其地下资源的背景 下进行的。该矿业法规定了每个项目的新的分配机制(10%的免费股份归国家所有,3%的从价税、5% 的产量分享等)。该国已就多个矿床(Ngovayang、Ntem、Djoum III、Bibémi)启动矿业协议谈判并签 署6份采矿合同,其中3份已开始实施(Minim-Martap铝土矿项目、Mbalam-Nabeba铁矿项目和Bipindi- Grand Zambi钛铁矿项目),正依托这一新机构将采矿业打造成国家发展的引擎 ...
