As one of the important basic research directions of mineralogy, the discovery of new minerals and the studies of crystal structure and crystal chemistry have always attracted the attentions of all researchers in the field. The research and discovery of new minerals are such achievements that reflect to some extent the national science and technology advancements and contribution to scientific discovery in this field. I have been involved in the study of some doubtful minerals in recent years, and the 23 new minerals we discovered since 2005 have been approved by the IMA-CNMNC. The approval of these new minerals benefited from the successful acquisitions of composition and diffraction data and structural refinement. In this paper, identification rules, proposal contents and data, classification and naming, and research contents and methods for new minerals are reviewed.
