Recent study has revealed that nickel can be extracted from low-grade ores using hydrogen plasma instead of carbon.
About Nickel:
It is a metallic element with a silvery-white, shiny appearance.
It is the fifth-most common element on earth and occurs extensively in the earth’s crust and core.
Nickel, along with iron, is also a common element in meteorites.
It occurs naturally in soil and water. It is also an essential nutrient for plants.
It has outstanding physical and chemical properties, which make it essential in hundreds of thousands of products.
Nickel occurs principally as oxides, sulphides and silicates.
India has substantial nickel laterite reserves, particularly in Odisha’s Sukinda region.
World Distribution: Indonesia (22%), Australia (21%), Brazil (17%), Russia (7%), Cuba (6%) and Philippines (5%) are the major countries having reserves of Nickel.
Applications
Its biggest use is in alloying - particularly with chromium and other metals to produce stainless and heat-resisting steels.
Nickel is an important metal used in several clean energy technologies, especially Electric Vehicles (EVs).
It is used in batteries, including rechargeable nickel-cadmium batteries and nickel-metal hydride batteries used in hybrid vehicles.
