目前大多数采金船都装配有橡胶铺面和金属格条的溜槽来捕收金属。在采金船上广泛采用溜槽选矿,是由于溜槽构造简单,没有机械部件,易于看管,同时有相当高的有价组分回收率,尤其是租粒级。但是溜槽亦有缺点,首先是当清溜时体力劳动量很大,因此在目前一般清溜时间间隔都过长(一般每天进行一次)。这就导致金和铂的捕收效率下降和细粒部分金属全部损失。为了强化溜槽的选别过程和机械化清溜,人们正在改进溜槽的构造。现在做了自动卸矿的、三面的、震动的和管形的金属溜槽,但是这几种结构的溜槽目前 At present, most gold mining vessels are equipped with chimney rubber paving and metal grid to capture the metal. The widespread use of chute beneficiation on gold mining vessels is due to the fact that the chute is simple in construction, has no mechanical components and is easy to care for and has a very high recovery rate of valuable components, especially for lease grade. However, there are also shortcomings in the chutes. First, manual labor is the major part of the liquidation. Therefore, the current general liquidity interval is too long (usually once a day). This leads to a decrease in both gold and platinum capture efficiency and a loss of all the fine-grained metals. In order to strengthen the chute sorting process and mechanized cleaning, people are improving the structure of the chute. An automatic unloading, three-sided, vibrating and tubular metal chute are now made, but these are several configurations of chutes currently
