This is because the rocks have to be crushed to very fine gravels that can allow for gold molecules to be dissolved in mercury or any other chemical used to extract gold from the ore. What this means is that in large scale mining the mines may have more than one crusher

Read MoreCrushing the ore can free the gold and allow recovery by gravity-based methods. In fact it’s very common that the gold in hard rock ores will range in the 30- to 200-mesh size range with most of the gold in the lower end of that range. The tried and true method for testing these ores in the field is hand crushing

Read MoreMay 05, 2018 The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed.The term should not be used, as it sometimes is, to designate a particular type or size of crusher
Read MoreAnother term that the old-timers used for this type of ore is free-milling, which means that the gold could be extracted from the rock by crushing and panning, and did not require a chemical process to work them. It is often free-milling gold deposits that can successfully be hunted with metal detectors to find specimen gold.
Read MoreJul 20, 2015 Assuming the specimens that you are crushing actually contain some gold, there is fine gold within all that quartz. All you have to do is separate it out. Panning . Now is the easy part. Once you have everything crushed down to fine texture, it is a simple matter of just panning out the contents. You will be left with just the gold.

The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold

Read MoreFor 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
Read MoreThe mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower.

This type of mineralization frequently makes gold recovery difficult by conventional techniques, such as amalgamation, gravity separation, or direct cyanidation
Read MoreA single piece of gold ore generally has very little actual gold content. Although a very rich ore may have some visible gold present, the vast majority do not actually have any visible gold present, and only crushing and processing of the ore will release the gold within to host material.
