gold processing and beneficiation from gold bearing rock
gold processing methods
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to Gold Mining Methods - Ground Truth Trekking More

5 Rocks That Contain Gold (and Where You Can Find Them)
5 Rocks That Contain Gold 1. Sedimentary Rocks Sedimentary rocks result from igneous and metamorphic rocks parting their gold into other stones. The process of parting can be due to hydrothermal, weathering, or erosion. When igneous and metamorphic rocks weather or erode, the contents are deposited into rivers or sediments in lakes.

Extracting gold from rock
30.08.2019When you mix the finely powdered gold-bearing rock with some mercury, the gold within the rock dissolves, to form what's called a gold amalgam. The next step in the process is to separate the gold amalgam from any 'unreacted' mercury. We did this by squeezing the crude amalgam through a small piece of chamois leather.
