金川铜镍硫化矿作为超大型铜镍矿床,资源丰富,除主要元素镍外,还有铜、钴及铂族金属元素伴生。随着常年开采,金川铜镍硫化矿矿石贫、细、杂的情况也愈发明显。由于采用选冶联合的铜镍分离方式,在以易浮的蛇纹石为主要含硅酸盐脉石情况下,随着原矿的不断贫化,仍需要保证MgO的合格,这为选矿工作带来非常大的难度和挑战。金川铜镍硫化矿浮选降镁问题作为世界性难题,由此得到广泛关注,针对其降镁问题的选矿药剂也在不断开发中。但在实际生产过程中,往往需要结合现场生产情况和实际生产成本,有些药剂对企业效益提升往往不大。总结阐述了金川公司往年针对铜镍硫化矿降镁药剂的研究进展,以及其他含氧化镁矿物降镁的选矿药剂的发展情况,望能给广大选矿工作者在铜镍硫化矿降镁方面提供技术参考。

In recent years, porous organic catalysts have been developed and become research hotspots in photo/electrocatalysis due to their inherent pores, high specific surface area, chemical and thermal stability, and diverse functional building blocks. Phenazine-linked organic catalysts,exhibited excellent conjugation, electrical conductivity, chemical, and thermal stability, could bring in N atoms with specific numbers and positions to regulate electron levels, anchor metals, and absorb near-infrared light, which expands solar energy utilization. These advantages of the phenazine-linked catalysts attracted our group and numerous researchers to conduct experimental and computational work on photo/electrocatalytic applications and mechanisms. This review summarizes the recent significant research progress, synthesis methods, photo/electrocatalytic performance, and applications of relative phenazine-linked catalysts. Furthermore, the photo/electrocatalytic mechanism was systematized and summarized by combining experiments and density functional theory calculations simultaneously.

Endocytosis is a crucial cellular process that takes up cargos by enclosing them in membrane-bound vesicles,and transports cargos to different parts of the cell,such as the lysosomes[1].Endocytosis is classified into several mechanistically and morphologically pathways,including clathrin-mediated endocytosis(CME)and caveolae-mediated endocytosis(CavME)[1,2].

随着双碳政策的实施,新能源汽车产业快速发展,高容量的锂电池得到了大规模的应用,因此,绿色、高效的提锂技术成为决定最终锂资源回收经济效益的关键因素。根据资源类型的差异,提锂技术可分为盐湖卤水提锂和矿石提锂技术两种。盐湖卤水主要用于生产工业级的碳酸锂,工艺流程简单,成本较低,但其生产条件较差,常伴随较高的Mg/Li。盐湖卤水提锂技术主要分为分步沉淀法和吸附法两种,分别用来处理低、高Mg/Li盐湖卤水资源。锂辉石、锂云母、锂黏土等锂矿石主要用于生产电池级碳酸锂,提锂工艺成熟,但生产成本高,环境污染较为严重,目前常用的工艺为硫酸焙烧法、硫酸盐培烧法、氯化焙烧法、石灰石焙烧法和碱性压煮法。结合盐湖卤水、锂辉石、锂云母和锂黏土等目前主要的锂资源,从资源储量分布、典型工艺流程、代表性矿山项目以及相应的运营成本分析等方面详细阐述了国内外锂资源提锂技术的研究和应用现状,并通过对不同锂矿资源开发技术在应用过程中的优缺点对比分析,从工业应用价值的角度来阐述现有技术中制约提锂效率的关键因素,并据此提出了不同锂资源提锂技术未来的发展方向,为提锂技术的优化更新提供相应的参考。
