Xikuangshan Shanxing Antimony Industry Co., Ltd. Concentrator is located in Lengshuijiang City, Loudi Prefecture, Hunan Province. It was commissioned in 1975 as a sulfur-oxygen mixed antimony ore concentrator with a designed capacity of 500 t/d.
The ore deposit is of low-temperature hydrothermal filling-replacement type. The metallic minerals are mainly stibnite and stibiconite, followed by bindheimite, with minor cervantite, valentinite, and sarabauite. Small amounts of pyrite and pyrrhotite are also present. Sulfide and oxide ores each account for approximately half of the feed. Gangue minerals are primarily quartz, followed by calcite, limestone, barite, gypsum, zircon, tourmaline, muscovite, sericite, epidote, and native sulfur. The wall rocks are silicified limestone, limestone, and shale. Antimony minerals are unevenly distributed in the ore. The mineral composition of the ore is shown in Table 5-11.
