江西省龙南县角洞稀土矿在开采过程中,从全局出发,安排资金,防治尾沙流失,积极开展水土保持工作,有效地减轻了对下游河道、水利工程和农田的危害,做到了采矿和保护环境同时抓。 这个矿是1970年发现的花岗岩风化壳离于吸附型富钇重稀土矿。露天开采,每生产1公斤产品就有1.4方尾沙。按现在产量计算,每年有尾沙21万立米。1980年以前开采规模小,产量少,尾沙排放少,当时对尾沙流失的危害没有引起该矿的重视。以后,随着生产规模的扩大,尾沙量逐年增加,对下游河床和农
In the process of mining, Angongdong Rare Earth Mine in Longnan County, Jiangxi Province, arranged funds for the prevention and control of tailings loss and actively carried out soil and water conservation work in the mining process, effectively reducing the damage to the downstream rivers, water conservancy projects and farmland and benefiting from the mining and Protect the environment at the same time. This mine was discovered in 1970 and the weathering crust of granite was separated from the adsorbed Yttrium rich rare earth. Open pit mining, each producing 1 kilogram of products have 1.4 square tail sand. According to the current production calculation, there are 210000 cubic meters of tail sand per year. Before 1980, the mining scale was small, the output was small, and the discharge of tailings was less. At that time, the harm caused by the tailings loss did not attract the attention of this mine. Later, with the expansion of production scale, the amount of tailings increased year by year, to downstream riverbed and farmer
