在西班牙南部的索蒂埃尔(Sotiel)黄铁矿由国营阿尔马格雷拉矿业(Minas deAlmagrera)公司经营。1977年对索蒂埃尔黄铁矿的重新开发进行了可行性研究,1980年开始进行地下勘探工作,随后掘进了竖井和斜坡道。1983年投产,到1984年实际上已完成初期工程,使产量增加,矿山达到设计生产能力。
The Sotiel pyrite in southern Spain is run by the state-run Minas de Almagrera. In 1977 a feasibility study was carried out on the redevelopment of the Sotyle pyrite. Underground exploration began in 1980 and subsequent shaft and ramp excavation. Put into operation in 1983, in 1984 has actually completed the initial project, so that production increased, the mine reached the design and production capacity.
