六股河口外海砂项目迈入规模化开采阶段_我的网站

A |     (ECNS) -- Chinese researchers have developed a method that can directly and precisely detect trace rare-earth impurities in high-purity rare-earth materials, overcoming a long-standing challenge caused by matrix interference, CCTV News reported Monday.    The breakthrough, led by a key laboratory under the State Administration for Market Regulation at Jiangxi University of Science and Technology, uses inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). The technique eliminates the need for matrix separation, offering higher sensitivity, accuracy and faster testing.    The team has also made advances in sample pretreatment and instrument calibration. The technologies are already widely used by rare-earth producers and testing institutions to improve quality control and testing efficiency.                        。    记者日前从市投资集团获悉，今年2月，绥中县六股河口外海域KT1区块海砂项目正式迈入规模化开采阶段。该项目保有资源量3891.32万方，可采资源储量3783.88万方，可采出矿石量3405.49万方，生产规模1843.2万方/年。         该项目坐落于绥中县六股河口外海域，矿区面积2.946平方公里。矿区距海岸线仅6公里，与六股河生态保留区无重叠，毗邻绥中港（35公里），陆域交通网络发达，区位优势显著。

C |          据悉，2024年2月，辽宁蓝金矿产资源开发有限公司成功摘取了绥中县六股河口外海域KT1区块海砂采矿权和海域使用权；5月，办理完成项目“两权”证书，并与中交广州航道局有限公司签订了项目一体化经营承包合同，6月—7月开展项目试生产运营。

D |          该项目采用全球领先的双洗射流船组技术，现已投入三组射流船组及一艘自吸自卸船，单日峰值开采量突破8万吨。未来将扩容至四组射流船组与八艘自吸自卸船，通过智能化调度与24小时连续作业，月均产能将跃升至300万吨，峰值可达600万吨，成为国家海砂战略储备的“核心支柱”。
