Diamonds typically are found embedded in carrotshaped pipes of volcanic rock called kimberlite, and harvesting the gems means separating them from this rock. Because the ratio of diamonds to kimberlite can be very low, harvesting usually is done on a large scale, and heavy machinery is necessary in the early part of the process.
a range of situations. The comparison study is aimed towards quarry and mining personnel intending to use a nonexplosive product for rock breakage, but not sure which product suits their situation best. Each product works on a slightly different principle, but the main similarity is that they all use high pressure gas with which to break the rock.

Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.
