木溜槽具有建设容易、无需动力、操作简单等优点,为国内的各砂锡矿选矿厂所广泛使用,但其主要缺点是劳动强度大,选矿回收率低(一般是40—50%左右)。1958年7月份我场选矿工人发明用小水枪清沟松沟法代替人力清沟松沟法,在生产中显示出这一革新具有很大的优越性。不但大大地节省了劳动力和减轻体力劳动强度,并且选矿回收率也显著地提高了,8月份的平均回收率达到83.04%,
The wooden chute has the advantages of easy construction, no power and simple operation, and is widely used for various sand and tin ore beneficiation plants in China. However, the main disadvantage is that the labor intensity is large and the recovery rate of ore dressing is low (generally about 40-50%). In July 1958 my field dressing workers invented a small water gun Qinggou Songgou Law instead of human Qinggou Songgou Law, in the production of this innovation has great superiority. Not only greatly saving labor and reducing labor intensity, and beneficiation recovery rate also increased significantly, the average recovery rate in August reached 83.04%
