| Name of the ORE | Tungsten Ore |
Chemical
& Physical Specifications |
Manganese 9.06 % Iron 9.21 % Tungsten 60.63 % Oxygen 21.10 % |
| Appearance | |
| Color | Black to grey or brown |
| Luster | Submetallic to resinous |
| Transparency | Crystals are translucent to opaque |
| Crystal System | Monoclinic; 2/m |
| Crystal Habits | Include the flat, heavily modified,
tabular crystals. The crystals are elongated along the c axis
and are generally flattened in the a axis direction. Also
as columnar aggregates and lamellar masses. Cleavage is perfect in one direction parallel to the a and c axes |
| Fracture | Uneven |
| Hardness | 4 - 4.5 |
| Specific Gravity | Approximately 7.0 - 7.5 (heavy even for metallic minerals) |
| Streak | Brown to black |

| Name of the ORE | Zinc Ore |
| It's Types | Sphalerite |
| Chemical Name | Zinc Iron Sulphide |
| Chemical Formula | (Zn, Fe)S |
Chemical
& Physical Specifications |
ZN: 48.05% Pb :4.14% Fe: 8.89% Ag: 0.004% |
| Appearance | |
| Color | Typically black but can be brown, yellow, reddish, green, and less commonly white or colorless |
| Luster | Adamantine or resinous or submetallic to earthy in massive forms |
| Transparency | Crystals are transparent to translucent |
| Crystal System | Isometric; bar 4 3m |
Crystal Habits |
Can be complicated with the rhombic dodecahedron, tetrahedron and combinations of these having cubic and tristetrahedron faces giving the crystals multiple faces of often indistinct forms. Cleavage is perfect in six directions forming dodecahedrons |
| Fracture | Conchoidal, but rarely seen because of frequent cleavage |
| Hardness | 3.5-4 |
| Specific Gravity | Approximately 4.0 (heavier than average, but light when compared to most metallic minerals) |
| Streak | Yellow to light brown |

| Crystal System | Tetragonal; 4/m 2/m 2/m | ||||||
| Crystal Habits | Include the pseudo-octahedral
tetragonal dipyramid. Minor pyramidal faces may truncate only
the top and bottom points, giving evidence of its tetragonal
symmetry instead of the isometric octahedron. Twinning is
common and repeated. Also granular and massive. |
