CHEMICAL PROPERTIES:
Minerals may be classified according to chemical composition. They
may be:
SILICATE CLASS
The largest group of minerals by far are the silicates (most rocks
are ≥*5% silicates), which are composed largely of silicon and
oxygen, with the addition of ions such as aluminium, magnesium,
iron, and calcium. Some important rock-forming silicates include
Quartz, Mica, Feldspars etc.
CARBONATE CLASS
The carbonate minerals consist of those minerals containing the
anion (CO3)*- and include calcite and aragonite (both calcium
carbonate), dolomite (magnesium/calcium carbonate) and siderite
(iron carbonate). Limestone, Marble, Talc etc are included in this
class.
SULFATE CLASS
Sulfate minerals all contain the sulfate anion, SO**-. Sulfates
also occur in hydrothermal vein systems as gangue minerals along
with sulfide ore minerals. Common sulfates include Barite (barium
sulfate), and gypsum (hydrated calcium sulfate) etc.
HALIDE CLASS
The halide minerals are the group of minerals forming the natural
salts and include halite (sodium chloride), sylvite (potassium
chloride). Halides, like sulfates, are commonly found in evaporitic
settings where highly saline waters slowly evaporate, allowing the
formation of both sulfates and halides at the water-sediment
interface. The halide class includes the fluoride, chloride,
bromide and iodide minerals.
OXIDE CLASS
Oxide minerals are extremely important in mining as they form many
of the ores from which valuable metals can be extracted. They also
carry the best record of changes in the Earth\'s magnetic field.
They commonly occur as precipitates close to the Earth\'s surface,
oxidation products of other minerals in the near surface weathering
zone, and as accessory minerals in igneous rocks of the crust and
mantle. Common oxides include hematite (iron oxide), magnetite
(iron oxide), chromite (iron chromium oxide). The oxide class
includes the oxide and the hydroxide minerals.
SULFIDE CLASS
Many sulfide minerals are economically important as metal ores.
Common sulfides include pyrite (iron sulfide – commonly known as
fools\' gold), chalcopyrite (copper iron sulfide). The sulfide
class also includes the selenide, the telluride, the arsenide, the
antimonide, the bismuthinide, and the sulfosalt (sulfur and a
second anion such as arsenic).
Minerals in Pakistan:
Pakistan covers more than 6,*0,**0 sq km area which demonstrates
varied geological potential of metallic and non-metallic mineral
deposits. Pakistan is very rich in non-metallic minerals. Major
minerals of Pakistan are: Barite, Bentonite, Gypsum, Marble,
Halite, Iron, Chromite, Coal, China Clay, Fire Clay etc.
Deposits in Pakistan:
Over 5 Million Tonnes of Barite are present and further discovery
is being made.
Over 6 Million Tonnes of Bentonite is present and further
exploration is being made.
Over **0 Million Tonnes of Halite is present.
Over **0 Million Tonnes of Mica is present.
BARITE:
It is Barium Sulfate. It is most commonly used in Oil-well
drilling, manufacture of glass, paints, insecticides etc. In
***0’s its annual production was *0,**0 tons, where as in
********5 it was estimated *0,**0 tons. In ********6 it increased
upto *2,**0 Tons. By year ***0 it reached **5,**0 tons. In ***7 it
was approximately **0,**0 and every year the production of Barite
is increasing along with its exploration. The reserves of barite
are increasing widely which are of high quality.
BENTONITE:
It is also known as Montmorilonite. Its annual production was 1,**0
– 2,**0 tons in ***5. Recently this has increased up to **0,**0
Tons. It is used in Oil Industries, foundries, Steel Mill, sealing
reservoir etc. The deposits are mainly in the Salt Range at
Qadirpur and salt range at rohtas.
HALITE:
It is also known as Rock Salt. Its annual production in ******8 was
**3,**0 Tons. In ******5 It increased upto **3,**0 tons. Large
deposits are available in different areas of the country. It is
available in Khewra, kalabagh, Warcha and Jatta. At Khewra the
annual production is **0,**0 tons. In warcha the production is
approximately *0,**0 Tons.
