Recovery of uranium, vanadium and fluorine from phosphate ...
RESULTS AND DISCUSSION It is clear from Fig. 1 that by treatment of Wasif phosphate ore under neutral conditions about 30% of the uranium was dissolved at a relative small acid use of 480 kg HC1/t ore. Under oxidizing conditions (by incorpo- rating 2% MnO2) uranium is dissolved in parallel with phosphate through- out.

Classification of Sedimentary Rocks
Ash: unconsolidated fragments under. 4 mm. Tuff: consolidated ash. Volcanic Breccia: angular fragments over 4 mm. Agglomerate: large proportion (>25%) of bombs. These rocks are classified on the proportions of vitric, crystal (mineral), or lithic material they contain, for example, "vitric lithic ash," or "crystal vitric tuff."

The Density of Common Rocks and Minerals - ThoughtCo
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).

Ore Ores - Paleontica
Ore. An ore is a type of rock that contains commercially viable quantities of a certain mineral substance. For example, rock that contains enough Hematite, may be iron ore.Often relatively small amounts of mineral are extracted from large pieces of rock. This causes large quantities of waste rock to be left behind, which can lead to significant environmental problems.

Acid Alcohol Leaching of Apatite
Typical processing involves mining the ore and beneficiating through sizing and flotation to produce a "phosphate rock" concentrate containing over 29 pct P2O5. This concentrate is ground to 90 pct minus 75 µm and leached to dissolve the phosphate. Apatite, Ca5(PO4)3(F, Cl, ½CO3, OH), is the primary phosphate mineral in the phosphate rock.
