ZINC ORE
Zinc ore refers to a naturally occurring rock or mineral that contains a significant concentration of zinc. Zinc is a chemical element with the symbol Zn and atomic number 30. It is a lustrous, bluish-white metal known for its excellent corrosion resistance, malleability, and conductivity.
COPPER ORE
Copper (Cu) ore is a naturally occurring mineral deposit containing varying concentrations of copper. It is an important industrial metal used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion.
NICKEL ORE
Nickel is a chemical element with atomic number 28 and the symbol Ni.
Due to its resistance to oxidation in air, nickel is used in the manufacture of coins, chemical tools and equipment, and many alloys such as German silver. Nickel is often found in nature with cobalt. It is important in the production of alloys (especially superalloys) and stainless steel. Furthermore, due to a natural property of nickel, it has the ability to change size slightly in a magnetic field. In nickel, this change is negative.
The oxidized form of nickel generally has a valence of +2, but valences of 0, +1, +3, and +4 have also been observed. However, the existence of nickel with a valence of +6 is also possible.
LEAD ORE
Lead ore is a naturally occurring mineral deposit containing varying concentrations of lead. It is typically extracted from the Earth’s crust through mining and is a significant source of lead, a soft, heavy, bluish-gray metal.
