Extracting gold from this type of ore is feasible for multimillion dollar mining companies, but almost impossible for the average person to do. Also consider that gold concentrations in ore is never consistent, often occurring in pockets rather than consistently throughout.
Removing the goldbearing 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.

In North America, there are very few mines that extract Silver alone; most mines primarily dig for zinc, lead and copper.
How to extract gold from sand? Differ from rock gold separation method, it is relatively simple to extract gold from sand. There are many simple methods, like panning, using a rocker box, using a sluice box, amalgamation and etc.. But it is proved that gravity separation method is the most effective and economic method through lots of practice.

How is the gold extracted from the rock? Extracting gold from the mined rock is a complicated process.
Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...
