Because 30% of the roughly 180 impact craters on Earth contain minerals or oil and gas, it seems that the cratering promotes the development of natural resources Some of the ores produced from impact-related effects on Earth include ores of iron, uranium, gold, copper, and nickel. It is estimated that the value of materials mined from impact ...
Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This small-scale form of gold mining has little effect on the body of water, but the large-scale practice of mining gold from ore can have tremendous negative effects on water quality.

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 pieces no larger than road gravel.

Gold is often found with other precious and metal-bearing minerals, including iron. These are called indicator minerals. Among the indicator minerals likely to be encountered with gold are Quartz, Magnetite, Garnet, Corundum (Sapphire), Emerald and (happily) Diamonds. So, it is indirectly that your metal detector will lead you to gemstones ...
Mining in South Africa was once the main driving force behind the history and development of Africa's most advanced and richest economy. Large-scale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes a few years later.
Interestingly, some of the same indicator minerals for gold are also indicators for diamonds. Among the most common indicator minerals for diamonds are chromium garnets, glassy green olivine, black picroilmenite, and magnetite. Garnet and magnetite are both good indicators for gold. So, if you find gold, there may be a diamond rock nearby.

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface ...

Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.
Actually, gold is about 19 times as heavy as water - about 3 times as heavy as iron. Knowing this makes finding it much easier. Because of its weight, gold will always sink to the lowest level as possible. As rain, wind, freezing & thawing, and geologic disruptions move the earth around, gold is freed up and relocates to the lowest point.
These minerals make up the solid Earth, the moon, and even meteorites. However, only 20 or so minerals compose the bulk of Earth's crust, that is, the part of the solid Earth accessible to human beings, extending from the surface downward to a maximum depth of about 55 mi (90 km). These minerals are often called the "rock-forming" minerals.
