Investigation of Ore Quality and Its Geological Significance in the Tawenchahanxi Mining Area of East Kunlun

The Tawenchahanxi mining area is a representative skarn-type deposit located in the Qimantage region, within the western section of the East Kunlun orogenic belt. Following over a decade of continuous development since exploration commenced in 2009, both the mining rights and detailed exploration rights have been submitted.This paper investigates various quality characteristics of the ore, including mineral composition, structural features, chemical composition, and ore types. The aim is to enhance our understanding of the mineralogical characteristics present in this area and to provide a foundation for future geological work.Research findings indicate that the mining area exhibits a rich diversity of ore types, with deposits characterized by multi-genesis processes, multiple stages of formation, and various mineral species. This complexity broadens prospecting opportunities within this region. The ore body contains 30.98% magnetic iron (mFe) content and 15.60% FeO content, resulting in an mFe/TFe ratio of 86%, classifying it as magnetite ore.Additionally, analyses reveal that the ore contains sulfur at 5.30%, arsenic at 0.30%, and MgO at 14.27%. The elevated levels of arsenic, sulfur, and MgO adversely affect the quality of iron concentrate and copper concentrate products. Furthermore, there exists a complex relationship among co-associated elements; thus, it is imperative to strengthen research on comprehensive recovery processes.
