MALANJKHAND COPPER MINE
Malanjkhand is the biggest base metal (Copper) Open pit Mine in India located at a distance of 90 kilometers
North-East of Balaghat In Madhya Pradesh, at an altitude of 576 MRL. It falls in the tahisil of Baihar, which is 22 Kms away from
the project, on the way to the district town, Balaghat MP, India Pin 481116.
Government sanction for the Project was obtained in June 1977 and stripping operation started in August 1979, after the first
shovel was commissioned and haul roads and shovel faces constructed. The mine at full production capacity will remove
11.5 million tones of overburden and waste rock, to recover 2 million tones of chalcopyrite ore of average grade 1.2 cu per annum.
A total of 22.6 Km of diamond drilling in 91 bore holes has been carried out till September 1978 to explore ore reserves upto a
depth 376 MRL
Understanding how a metallic-ore deposit forms requires an understanding of the geological processes that concentrate metals.
The behaviour of metals in the Earth’s crust begins with identifying possible sources for the metals. The metal source may be
vapour dissolved in an intruding molten rock beneath the Earth’s surface, or it may be black shales heated and deformed to the point
where their metals are released. However, the metals do not have economic value in a dispersed and disseminated state.
It is critical to understand, down to the atomic level, the chemical conditions controlling the mobilization of metals. The mobility
of metals combined with a clear path for their migration is the first step toward concentration of metals in a restricted space.
The path may be outlined by small or large structural irregularities in the rock. Metal transport may be in response to chemical
gradients as metal-bearing fluids seek a state of chemical equilibrium with the surrounding rocks. Mobility leading to spatial
confinement and concentration is essential for an ore deposit to be economic.
After their journey, be it short or long, the metal-bearing fluids release their metals to form minerals, most commonly by bonding
with other elements. For instance, metals bonding with oxygen are known as oxides and metals bonding with sulphur are known as
sulphides. These minerals may occur freely in the host rock or in veins together with quartz or calcite. It is the deposition of
these minerals that provides the copper, molybdenum, lead, zinc, gold, silver, and many other metals for our daily use.
