There is no one chemical named "ore". However, every ore contains lots of atoms, in covalent or crystalline bonds. This makes every ore a compound of some kind, or even a collection of physically connected compounds.
Iron ore is a mixture.
The most common ore of aluminium is bauxite.
Calcite is calcium carbonate - CaCO3.
It is a mixture of an Iron compound and a rock substrate. Iron ores are usually rich in Iron Oxides (a compound) and minerals. Since the iron is not chemiically bonded to the mineral substrate it is a mixture.
In a flotation cell, chemicals called collectors are used to selectively attach to the metal compound particles in the ore. These collectors enable the metal compound particles to become hydrophobic, allowing them to attach to air bubbles and float to the surface for collection while the gangue particles remain in the water.

Iron ore is a mixture.
The natural compound of a metal is called Ore.
Silver ore is a heterogeneous mixture, as it contains various minerals and impurities along with the silver.
A solid may be an element (iron), a compound (iron oxide), a mixture (iron ore).
You can not actually make metal but you can obtain metal from an ore of that metal. The ore is a chemical compound of that metal and the process of smelting the ore involvesf breaking the compound up using heat and "reducing it" essentially removing oxygen - to leave the pure metal.
Alloy is a combination of metals with in an ore. This makes the ore un-pure and needs to be smelted seperatly.
The most common ore of aluminium is bauxite.
The ore contain frequently the metal in a compound and also have many impurities. The concentration of the metal is generally low.
To obtain an element from its compound ore, the ore must undergo a process called extraction. This typically involves crushing the ore, heating it to high temperatures, and then using chemical reactions or other separation techniques to isolate the desired element in its pure form. The extracted element can then be further processed and refined as needed.
