位于矾山镇南的磷铁矿床埋深120～280米。主要矿石为品质磷灰石,氟磷灰石及矾钛磁铁矿。通过井下坑采,引出地表。在浮选中,要加入天然环境不存在的选矿化学药剂。然后人为决定元素的集散,留下的废弃物主要为废石、尾矿和选矿废水(尾水),这些废弃物将参加环境物质循环。 Phosphorus iron ore deposit located in the south of the town of Alum is 120 ~ 280 meters deep. The main ore for the quality of apatite, fluorapatite and vanadium titanium magnetite. Pit through the underground mining, leads to the surface. In flotation, to join the natural environment does not exist in mineral processing chemicals. Then the human decided to distribute the elements, leaving mainly waste rock waste, tailings and dressing wastewater (tail water), the waste will participate in the recycling of environmental material.
