average density of gold ore mining

What Does the Grade of a Gold Mine Refer To?

Feb 07, 2020  The World Gold Council defines a high-quality underground mine as having a gold ore density between 8 and 10 g/t, while a low-quality underground mine has a gold ore density of 1 to 4 g/t.

Grade and tonnage model of Placer Au-PGE - USGS

In order to conform to other deposit models herein, deposit volume and grades have been converted to metric tons and grams per metric ton using 2.0 metric tons per cubic meter--the average density of wet sand and gravel. Gold grade is correlated with tonnage (r = -0.35) and with silver grade (r = 0.66, n = 16). See figs. 196, 197. Figure 196.

What is Gold Ore worth? High Grade Mining Ore

For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold.

The Density of Common Rocks and Minerals

Jan 23, 2020  The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
