According to regulation of Ministry ESDM No.5/2017 stated that the minimum grade of zinc concentrates to be exported is 51%. Therefore, it is necessary to do a beneficiation process for sphalerite ore to fulfil the requirements. Sphalerite is hydrophobic mineral, therefore it is the best way to processed sphalerite by flotation.
Supernormal enrichment of cadmium in sphalerite is frequently observed in some sedimentary-hosted zinc-lead deposits, although related fluid process remains unconstrained.
Sphalerite is the only ore of zinc, and can also be used as an ingredient in the smelting of brass. In the game, sphalerite is found as veins in metamorphic layers. Interestingly, dwarves can smelt sphalerite into zinc while the stone itself does not melt, but sublimates (going from solid to gas without melting). Smelting
The origin of the abundant hydrothermal vein-type Pb–Zn deposits in the Qin-Hang Metallogenic Belt (QHMB) in South China remains disputed due to the poor constraints on the ore-forming process.
