Chromium, and Aluminum. Nonmetallic resources are things like sand, gravel, gypsum, halite, Uranium, dimension stone. A mineral resource is a volume of rock enriched in one or more useful materials. In this sense a mineral refers to a useful material, a definition that is different from the way we defined a mineral back in Chapter 5.

Small ores can be found scattered around on the surface of the ground. These are samples of what ore veins are located within 35 blocks underneath the soil, so they're somewhat important. In the majority of cases, it is a sample of a vein in the top layer of stone. However, in areas where the top layer is thin enough, the vein may be located …
Chalcopyrite is easily the most widespread copper-bearing mineral. A common mineral found in almost all sulfide deposits, chalcopyrite usually occurs in medium-temperature and high-temperature hydrothermal veins …

Goethite (a.k.a. Limonite): Goethite is a hydrous (water-bearing) iron oxide that forms as a direct precipitate in marine water and bogs, and as an alteration of other iron-bearing minerals. Along with hematite, goethite is the other mineral that makes up most of the rust on natural and artificial iron exposures.
The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that a sample of ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. As general information, kg/cu.m divided by 16.01846 = lbs/cu.ft. To help with the table, unit converters are included at the top of ...
