Placer and lode gold on gold extraction boat, extraction process is similar, here mainly to talk about the difference between placer and lode gold.
在金矿中，按矿物形态来说，又分为岩金和砂金两种，砂金实际上是山体中的岩金被河水冲刷、金与石英矿脉分离而成的。
In gold, according to the morphology of minerals, rock gold and placer gold two, placer gold is actually rock gold mountain is water erosion, gold and quartz vein separation and.
在地壳里的黄金都是分散的细小金砂或金渣，但有一种“狗头金”——自然金块，那是河床中的砂金千百万年间被碳酸化合物络合的凝聚物，淘金者碰到大块狗头金那可是一生的好运气。
Gold in the earth's crust is dispersed fine gold sand or gold slag, but there is a nugget of natural gold, it is millions of years of placer gold in the bed of the river by carbonate complexes of condensates, gold diggers met large nugget that life but good luck.
再说岩金，金子藏在岩石中的石英矿脉里，需要人们先找出含金的岩石，然后开采矿石，破碎和球磨，金成为单体金后再用重力选矿方法或浮选法提纯得到黄金。
Say rock gold, gold was hidden in the rocks of quartz vein, people need to find the gold of rock and ore mining, crushing and milling, gold has become single gold and then gravity separation method or flotation and purification of gold.
