Mineralogy, mining

High Fe sphalerite contains tenths of a percent, India, beds and chalcopyrite — an order of magnitude less, and pyrrhotite, cassiterite — thousandths of a percent. The total content of this element in the lithosphere of the Earth is about 0.25 g/t. World consumption of this metal in the XXI century is growing rapidly and by 2009 was able to reach 900 m. It is an indispensable material for high vacuum technology today and 1 kg In is about $ 700. The consumption of it in the world is steadily growing and by 2006 it reached 860 T.

Technical characteristics

The density of India at 20 °C is equal to of 7.31 g/cm3. It dissolves in nearly all acids. Resistant to alkaline solutions, able to withstand heat up to 800 °C, but after flashing flame violet-blue color with the formation of oxide.
