黄金是硬通货也是国家急需的贵重金属,其产量的四分之一采自砂金矿。作为移动式联合采金船以其效率高、处理量大和成本低逐渐在各国砂矿采选中得到广泛地应用。我国黑河金矿局从六十年代试制采金船来代替原手工和半机械化采选,至1973年即占全部采选的85％;至1984年黑龙江省采金船已达62条,船采机械化比重已达95％以上,近来又有更大的发展。 南方采金船开展较迟,但也逐年增长,至1984年,已有四川白水2条300HS和湖南邵阳11条100升采金船投入生产。江西1987年已有修水1条50HE和
Gold is hard currency is also an urgent need for the country’s precious metals, one quarter of its production was collected from gold and sand. As a mobile integrated gold mining vessel with its high efficiency, large capacity and low cost gradually in the sand mining mining in various countries have been widely used. China’s Heihe Gold Mine Bureau trial production of gold from the sixties gold ship instead of the original hand and semi-mechanized mining, to 1973, accounting for 85% of all mining; to 1984, Heilongjiang Province gold ship has reached 62, mining The proportion of mechanization has reached more than 95%, and more recent developments. The southern gold mining vessel was launched later, but also increased year by year. By 1984, two 300HS mining vessels from Baishui, Sichuan Province and 11 100-liter mining vessels from Shaoyang, Hunan Province had been put into production. Jiangxi Province in 1987 has a water repair 50HE and
