Nickel, characterized by its silvery-white hue, is widely used as a fortifying element, infusing other metals with enhanced hardness, strength, and resistance to corrosion. Its pervasive presence in everyday objects, from domestic appliances to high-demand industrial materials, underscores the integral role that nickel mining plays in our daily existence. This versatile metal is utilized in the fabrication of steel, superalloys, stainless steel goods, coinage, electric vehicle batteries, magnets, among other products. As one of the most prized materials in the mining sector for the 20th and 21st centuries, nickel has propelled Indonesia’s nickel mining industry into a leading position on the global stage.
