Crushing and Sieving Purdue University

When a sample arrives it is first crushed and sieved. This is to obtain the correct grain size for the rest of the separation process. The ideal grain size is 0.25-0.50mm. There are two crushing machines available; a jaw-crusher and a disc-pulverizer. Samples are usually run through the jaw-crusher first, and then the pulverizer.

Crushing Ore for Gold Veins Hardrock Lode Mining Rock

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.
