China is a vast country, river systems development, geological conditions of gold is superior, with rich placer mineral resources. According to incomplete statistics, China is known to have more than 3200 gold placer point, tens of thousands of placer gold mineralization and geochemical anomaly area, which are distributed in 27 provinces (municipalities and autonomous regions), almost all over the provinces. So how does our country separate the sand gold mine? Here we briefly introduce the method of mineral processing.

总观我国砂金矿产资源具有点多、面广、成群成带、集中分布和资源储量雄厚等特点。这样一定程度上给砂金矿的选矿工作带来了便利。一般来说，我国砂金矿的选矿原则是先用重选法最大限度地从原矿砂中回收金及伴生的各种重矿物，继而用重选，浮选，混汞，磁选和静电选等联合作业将金和各种重矿物彼此分离，以达到综合回收的目的。

The general view of gold mineral resources in China with many points, wide, into groups with centralized distribution and strong reserves etc.. This to a certain extent, the mineral processing work has brought convenience to the sand gold mine. Generally speaking, our placer mine the dressing principle is first with gravity maximum limit to from the original ore recovery of gold and the accompanying the of all kinds of heavy minerals and then by gravity, flotation, amalgamation, magnetic separation, electrostatic separation, joint operations will gold and all kinds of heavy minerals are separated from each other, in order to achieve the purpose of comprehensive recovery.
