Minerals in the Cu-Sn-Se system, an experimental study
Original language description
Copper, tin, and selenium are frequently considered to be critical metals as a result of increasing demand and insecure supply. We studied synthetic analogues of minerals belonging to the Cu-Sn-Se system. We further assessed the phase relations in the system at 300 oC. For the purpose of this study the silica-glass tube method was used. The experimental products were evaluated by means of XRD and EMPA. The following binary phases: SnSe, SnSe2, Cu3Sn, Cu6Sn5, Cu2-xSe, CuSe, and CuSe2; and the ternary phase Cu2SnSe3, an analogue of okruginite, were proved to be stable at 300 oC. Okruginite forms stable associations with Cu-selenides and Sn-selenides at 300 oC. The phase SnSe, an analogue of svetlanaite, forms a stable association with copper-tin alloys and Cu2 xSe. The SnSe2 phase, so far not known to occur in nature, forms stable association with svetlanaite and okruginite. The SnSe2 phase should be sought in such assemblages in low-temperature environments with high oxygen fugacity and high Se/S fugacity ratio. Such association can be expected in selenide vein-type deposits, vein-type uranium deposits, unconformity-related uranium deposits, or Au-Ag epithermal volcanic-hosted deposits.
