List of Metals and their ores
Metals exist in a combination with other elements in the form of ore. Before discussing the metals and their ores, let’s first understand what is an element and what are the various types of elements.
1. What is an Element?
A substance that cannot be broken down into another simpler substance is referred to as an element. Although elements are not changed by chemical reactions, nuclear reactions can form new elements.
Every element is made up of atoms of its own kind. This is why the chemical elements are so different from one another. Every element in the universe contains at least one or more atoms. Currently, 118 elements are known, of which 94 are naturally occurring and the rest are produced artificially.
2. Types of Element
There are the three types of elements:
- Metals
- Non-Metals
- Metalloids
2.1. Metals
Metals are good conductors of heat and electricity, as well as malleable (they may be hammered into sheets) and ductile (they can be drawn into wire).
At room temperature, most of the metals are solids with a characteristic silvery shine. Mercury is the only common metal that is liquid at room temperature.
Some examples of metals are:
Aluminium, Copper, Iron, Tin, Gold, Lead, Silver, Titanium, Uranium, and Zinc.
2.2. Non-Metals
Non-Metals are not malleable or ductile, and they are poor conductors of heat and electricity.
At room temperature, most non-metals are gases that do not conduct electricity, such as oxygen, hydrogen, and chlorine.
At room temperature, a few non-metals, such as carbon and sulphur, are solid state.
Some examples of non-metallic elements are:
Hydrogen, Chlorine, Fluorine, Carbon, Nitrogen, Phosphorus, and Selenium.
2.3. Metalloids
A metalloid is a type of chemical element with properties that are intermediate between those of metals and nonmetals.
They are more like non-metals in terms of physical qualities, but under particular conditions, several of them may be made to conduct electricity.
Some of these semiconductors are very important for computers and other electronic devices.
Some examples of Metalloids elements are:
Boron, silicon, germanium, arsenic, antimony, and tellurium
3. List of Important Metals and their ores
Ore - Ores are naturally occurring rocks that contain sufficient amounts of metals or metal compounds to make extraction feasible.
The process utilized to extract a certain metal from its ore is determined by the metal's reactivity and thus the ore's stability.
Very reactive metal ore is melted and electrolyzed using a DC (direct current) power supply. The negative electrode attracts the positive metal ions, which accept electrons.
