(一)概况我矿矿层顶底板为紫红色泥质细岩或泥页岩,容易风化,原矿含泥高达15.49％。铜选矿厂离竖井不远,以自流滑坡来矿。马尔溪流经选矿厂一侧向下游十多公里汇入锦江。两岸居住着几百户农家,灌溉上千亩农田。 (二)溢流归队前铜矿石损失情况原设计未考虑脱泥,1970年试生产后,由于含泥多而使设备堵塞、卡死、运输机打滑。泥矿砂矿混合浮选造成
(I) Overview The top and bottom floors of the mine are mauve shaly fine rock or shale, easy to weathering. The ore contains up to 15.49% mud. Copper concentrator not far from the shaft, to gravity landslides to mine. Mal Creek flow through the side of the beneficiation plant more than 10 kilometers downstream into Jinjiang. Hundreds of families live on both sides of the Strait, irrigating thousands of acres of farmland. (B) of copper ore before the overflow loss of the original design did not consider the desliming, 1970 trial production, due to mud and more equipment plugged, stuck, transport aircraft slippery. Mud ore ores caused by mixed flotation
