For most small-scale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.

Free-milling gold can be further classified into low grade and high grade which helps determine the most economical and optimal gold recovery method. Low Grade. Low grade free-milling gold deposits contain less than 1 g/t of gold. This low grade ore is crushed and heap leached to recover the gold. While heap leach recoveries are lower than in conventional gravity-cyanidation, the savings in capital expenditure
Once the ore has been broken up into fine dust, testing for free gold content in hardrock ore can be done using some type of gravity method. A simple gold pan can be used to sample small amounts of crushed ore, or if a decent water supply is available then it can be run through many types of separation devices.
Rock Crushing methods and How to recover gold from Ores. So as you are crushing, stop and screen your material, removing any free gold which has already separated from
Dynamite was introduced in the 1870s, allowing miners to dig deeper for gold. Arrastre. The first use of machinery in the gold rush was in the 1860s at an underground mine in Tangier. The machine, called an arrastre, used a giant stone attached to a wooden arm to crush the gold-bearing rock.
Panning was the oldest and simplest way to separate gold from surrounding rock. It was the most basic method to obtain placer gold. The basic procedure was to place some gold-bearing materials, such as river gravel, into a shallow pan, add some water, and then carefully swirl the mixture around so the water and light material spilled over the side.
