what-type-of-mining-was-used-to-find-gold?

The methods of gold mining have changed over the years in various ways. In the past, miners used basic techniques like gold panning, which is the process of using a shallow container known as the gold pan to sift through sediment in the river to find gold. This method was practical for early prospectors who were working on a small scale.

The gold mining life cycle

Miners, mining materials and equipment are transported deep underground via the mine cage in the vertical shaft, which can go to depths of up to 3.5km below the surface. Open-pit gold mining also takes place in South Africa. This is a mining technique which excavates at the surface to extract ore.

» Different Kinds of Sampling

In placer mining, there are fundamentally two kinds of sampling: 1) Discovery: Attempting to locate a higher-grade deposit of value inside of a larger volume of lower-grade material. 2) Quantification: Extracting and analyzing smaller portions, to gain a perception of how much value exists within a larger volume. The general concept behind sampling is to …
