泸州位于四川南部,境内的古蔺、叙永2县赋存有丰富的硫铁矿资源,具有极为重要的开发价值。本区有硫铁矿产地25处,多构成大、中型矿床.据资料统计,全区硫铁矿储量为21.9亿 t,占川南预测储量的48.44%.目前区内主要有大树硫铁矿(年产硫铁矿30万 t,硫磺1.3万 t,硫精砂6万 t)和石屏磺厂(年产硫精矿9万 t,硫磺2万 t 左右).据统计,1989年全区开采矿石量63.8万 t,矿石主要用于土法提炼硫磺及硫精砂外运制硫酸.为了进一步综合开发利用本区硫铁矿资源,提出如下建议。①煤、硫共生是本区硫铁矿层的一大特点.在开采中,常是采煤弃硫或采硫弃煤,既浪费人力、物
Luzhou is located in southern Sichuan, the territory of Gulin, Xuyong County 2 is rich in pyrite reserves, has a very important development value. According to statistics, the reserves of pyrite in the whole region are 2.19 billion tons, accounting for 48.44% of the predicted reserves in southern Sichuan Province. At present, there are mainly large tree pyrite (With an annual output of 300,000 tons of pyrite, 13,000 tons of sulfur and 60,000 tons of sulfur concentrate) and ShiPingSuo plant (annual output of 90,000 tons of sulfur concentrate and 20,000 tons of sulfur) According to statistics, in 1989 District mining of 638,000 tons of ore, the ore is mainly used for the extraction of sulfur and sulfur dioxide from the soil outside the system of sulfuric acid .In order to further comprehensive utilization of pyrite resources in this area, made the following recommendations. ① coal, sulfur symbiosis is a major feature of pyrite in this area.In the mining, coal mining is often abandoned sulfur or coal mining waste, waste of manpower and material
