2. Galena ore of lead, lead acid batteries are used for
automobiles, power supplies for communication
facilities, enery storage system associated with power
generation and hybrid vechicles.
Chalcopyrite is primary ore of copper, copper is used in
virtually all electrical wiring (except for power lines,
which are made with aluminium), heating elements,
motors, renewable energy, internet lines and electronics.
Pyrite production of sulphuric acid for the chemical
industry and the fertilized industry.
3. Molybdenite is used as a catalyst to remove sulfur from
fossil fuel. Molybdenum is used to make alloys, in steel
alloys to increase strength, hardness, electrical
conductivity and resistance to corrosion, in engines,
heating elements and drill.
Antimony is found in naturally occur as the sulfide
mineral stibnite, 60% of antimony is consumed flame
retardants and 20% is used in alloys for batteries, plain
bearings and solders.
Mercury occur in deposits mostly as cinnabar, used in
thermometers, barometers and fluroscent lamps.
Cobalt is used as battery materials, super heated resistant
alloys, tool steels, hard alloys and magnetic materials.
4. Hematite is ore of iron, use for pigment, heavy media
separation, radiation shielding, polishing compounds,
fabricated metal products, magnets, industrial
machinery, transportation equipment and instrument.
Magnetite is iron ore for steel manufacture. As a raw
for manufacturing steel in iron and steel industries,
used in electronics, manufacturing, automotive,
construction and building.
5. Corundum use as a precious gem, owning to the
extreme hardness of the material, used for grinding
optical glass and for polishing metals.
ruby is used in watch industry.
Bauxite is used in chemical industry, refractory,
cement, steel and petrol industry.
Copper oxide is a semiconductor metal with unique
optical, electrical and magnetic properties.
Chromium extracted from chromite is used in chrome
plating and alloying for production of corrosion
resistant superalloys, nichrome, stainless steel and
refractory material because it has a high heat stability
6. Brucite can be use in causite and dead burned
magnesia production. A source of magnesia and as
refractory additive.
Gibbsite is the mineral form of aluminium
hydroxide. Used as a fire retardant filler for
poloymer applications because it is colourless
inexpensive and has good fire retardant properties.
Magnesium hydroxide is used for flame retardant
for articles such as roofting, isolation material,
plastic articles and coatings.
7. Fine goethite specimens are rare and therefore are
valued collectibles. Banded or iridescent varieties are
cut and polished into cabochons for jewelry making.
Diaspore commonly used in refractories: cosmetic and
soaps, ceramics, paper, rubber, potteries, toys and
statues.
