沙里淘金的原理:金子的密度比沙子的密度大得多,在水的冲击下,沙粒被水流带走,而金子的颗粒就留在容器里.这就是沙里淘金的原理,因为金子的化学性质安稳,通常不与其他物质作用,所以它以游离态存在于沙石中,在天然的风化作用下,岩石破碎,终究构成沙子和土,而金子就埋藏在其间,在溪流的搬运下,泥沙、金子的颗粒和水一同移动,它们移动的速度和情况不一样,所以在河床的某区域能够构成金沙富积的地带,即是我们渴望找到的淘金地,我们在这设立淘金设备,将河沙挖到淘金斗里,再抽河水冲斗里的沙子,许多的沙子就被水带走,在斗里留下的即是金灿灿的金子.
Sharitau Kim's principle: the density of gold sand density is much larger than that under the impact of water, sand and water away, gold particles in the container. This is Sharitau Kim's principle, because the stable chemical properties of gold, usually not with other substances, so it is in free state in the sand and in natural weathering, rock crushing, eventually forming sand and soil, and the gold was buried here, in stream handling, sediment, gold particles and water to move, they move fast and are not the same, so in a certain area of bed can constitute Jinsha enrichment zone, that is we are eager to find the gold rush, we set up the equipment in this, the river sand to dig gold bucket, then draw the river sand in the bucket, a lot of sand was left in the bucket of water away, is gold.
