和成矿业洗矿系统改造实践

针对和成矿业井下原矿含泥量和含水量较大，且矿泥中存在绿泥石、高岭土等黏土类矿物，造成供矿系统粘堵严重，系统台时量仅为设计水平一半的问题，对原矿进行了洗矿工艺研究。通过洗矿工艺，将原矿中的矿块和矿泥分离，实现矿块和矿泥按粒度分选，彻底解决了供矿系统粘堵严重的问题，稳定了磨选系统给矿量。

A mini review on two-dimensional nanomaterial assembly

Two-dimensional (2D) nanomaterials have attracted a great deal of attention since the discovery of graphene in 2004, due to their intriguing physicochemical properties and wide-ranging applications in catalysis, energy-related devices, electronics and optoelectronics. To maximize the potential of 2D nanomaterials for their technological applications, controlled assembly of 2D nanobulding blocks into integrated systems is critically needed. This mini review summarizes the reported strategies of 2D materials-based assembly into integrated functional nanostructures, from in-situ assembly method to post-synthesis assembly. The applications of 2D assembled integrated structures are also covered, especially in the areas of energy, electronics and sensing, and we conclude with discussion on the remaining challenges and potential directions in this emerging field.
