砂金的搬运方式，根据沈阳矿产所吕英杰等同志的研究有四种：单矿物（金粒）搬运，“运载”式搬运，接力式搬运，金在水溶液中搬运。我国主要江河如黑龙江、黄河、长江、珠江、额尔齐斯河、辽河、滦河等均产砂金。砂金的分布不是普遍的，一级水系长江、黄河、额尔齐斯河等虽有砂金分布，但品位低，深度大，颗粒一般较细。目前尚难利用。二级水系砂金矿化比较普遍，如湘江、沅江、昌江、汉水、洛河等的沙洲、沙坝、边滩大都分布有砂金矿点。但品位低、规模小。3～4级支流河谷是砂金主要赋存部位，也是工业开发的主要对象。5级以上的支沟细谷规模小、品位较富，是民采的主要对象。

由于水流动态所致，我国西部砂金主要以冲洪积、冰碛型为主，东部地区以冲积型为主。内蒙古高平原区以洪积型为主。

The placer gold of the mode of transport, according to the study of Shenyang mineral the LV Yingjie comrades there are four: Handling single minerals (Jin Li) and "carry" handling, handling relay, gold in aqueous solution in handling. China's major rivers such as Heilongjiang, the Yellow River, the Yangtze River, Pearl River, Irtysh River, Liaohe River, Luanhe River were producing gold. The distribution of placer gold are not universal, the first-order stream Yangtze River, Yellow River, Irtysh River and although the distribution of placer gold, but low grade, depth, particles are generally smaller. At present, it is difficult to use. Secondary drainage systems of placer gold mineralization is relatively common, such as the Xiangjiang River, the Yuanjiang River and the Changjiang and Hanjiang River, Luo, etc. of the sandbar, sand dam, beaches are mostly distributed placer gold deposits. But the grade is low, the scale is small. 3 ~ 4 tributary Valley is the main gold occurring position, is also the main object of industrial development. 5 levels above the small valley of the small valley, rich in quality, is the main object of the people.
Because the water flow caused by dynamic, China mainly in the alluvial placer gold, moraine type, the eastern region is dominated by alluvial type. The high plain area of Inner Mongolia is dominated by flood.
