Placer Gold Prospecting Method Introduction

Placer gold prospecting method introduction

Placer gold mineral resources in China has the characteristics of point, a wide range of groups into the band focus on distribution and strong reserves, is one of the major placer gold resources in the world. Placer gold content is extremely low, must go through the separation, purification before smelting and processing of placer gold beneficiation. It must include the separation and purification process. The actual situation, due to waste rock part of the chunk does not contain gold placer inevitably exist, so the advance screening out this part of the waste rock has an important significance for improving the efficiency and capacity of the mineral processing equipment.

Placer gold prospecting method introduction:

Placer gold prospecting methods are various, and there are five kinds of commonly used methods:

1) natural heavy sand . Natural heavy mineral is a great placer gold particle density (specific gravity), only a panning dish will be able to direct sorting out the expected material. sampling at the surface of loose debris deposition or the depths of digging. In the wild panning directly determine whether there is placer gold .

2) The project re-sand method is to use the sand to drill exploratory well project to penetrate loose sediments and systematic sampling to understand the loose sedimentary gold-bearing situations and an effective method to directly determine the grade of gold-bearing layer.

3) the old placer gold mining survey . A lot of placer gold district of the upper reaches of the river or tributary thin Valley common placer gold by hand the old mining track, they are a valid indicator of placer gold prospecting.

4) The geological and geomorphological analysis of geophysical and new aviation technology. It is the basic method for placer gold prospecting, mainly used for the prediction of conditions for analysis of placer gold mineralization and metallogenesis favorable area

5) folk looking for some experience of the gold placer.
