Because an ore contain many components which are not uniformly distributed in the mass.
Copper can be extracted from its ore through a process called smelting. The ore is first crushed and then heated in a furnace to separate the copper from the other elements. The molten copper is then collected as a metal.
The chemical formula for copper ore can vary depending on the specific mineral composition. However, a common mineral form of copper ore is copper pyrite, which has the chemical formula CuFeS2.
The most often mined ore of copper is the mineral chalcopyrite.
Iron is metal that can be extracted from ore there is also titanium aluminum copper and others
The copper will explode ??? * it gets wet * the copper ore goes through several stages of hydration as the water is absorbed, changing its crystal structure. This is a form of structural change but I've never seen it explode.
a copper ore
Pure Iron is considered as Homogeneous. Whereas, Iron with rust or other impurities is Heterogeneous.
The mineral malachite is an ore of copper.
A refinery separates copper from its ore.
Iron ore is a heterogeneous mixture.
Most copper ore occurs as copper in combination with oxygen, yes.
The most common ore of copper is Copper pyrite CuFeS2 but other ores are also exist.
Copper is typically extracted from the ore chalcopyrite, which is a copper iron sulfide mineral. Other ores that contain copper include bornite, chalcocite, and covellite.
Copper Ore.
It depends upon nature of ore the most common ore of copper is Copper pyrite CuFeS2. the extraction of copper from this ore involves the following steps, 1-crushing, 2-grinding, 3-concentration of ore, 4-roastiong, 5-smelting, 6- preparation of blister copper and 7- electrorefining of blister copper.
Gold is metal that is a homogenous mixture. It is not a heterogeneous mixture, because a heterogeneous mixture can be physically separated.
Silver ore is a heterogeneous mixture, as it contains various minerals and impurities along with the silver.
