Depending on the reactivity of metal combined in the ore . It can be done by thermal reduction , or by electrolysis.
NB
Iron ore is reduced by thermally, in the blast furnace.
Bauxite ( Aluminium oxide) is reduced by electrolysis, in an electrolysis plant.

What non metal is used to remove oxygen from metal ores?
Carbon is commonly used to remove oxygen from metal ores through a process called smelting. The carbon reacts with the oxygen in the metal ore to form carbon dioxide gas, leaving behind the pure metal.
How is carbon used to extract metal from ores?
Carbon is used as a reducing agent in the extraction of metals from ores because it has a high affinity for oxygen. When carbon reacts with metal oxides at high temperatures, it removes oxygen from the ore through a process called reduction, leaving behind the pure metal. This method is known as smelting and is commonly used to extract metals like iron from their ores.
How are sulfide ores turned into oxides?
Sulfide ores can be turned into oxides through a process called roasting, where the ore is heated in the presence of oxygen. This causes sulfur in the sulfide ore to react with oxygen and form sulfur dioxide gas, leaving behind metal oxides. The metal oxide can then be further processed to extract the desired metal.
How is iron usually separated from its ores?
Iron is usually separated from its ores through a process called smelting, which involves heating the ore with a reducing agent such as coke. This process removes the oxygen from the ore, leaving behind the pure iron metal. The impurities in the ore combine with the flux to form a slag that is then removed.
Are metal ores synthetic?
No, metal ores are naturally occurring minerals that contain metal elements in their chemical composition. They are formed through geological processes such as volcanic activity, sedimentation, and metasomatism over millions of years.
What element is removed from ores when they are reduced?
The element that is removed from ores during the reduction process is oxygen. This reduction process involves adding a reducing agent, such as carbon or carbon monoxide, to react with the oxygen in the ore to form carbon dioxide or carbon monoxide gas, leaving behind the metal in its pure form.
What non metal is used to remove oxygen from metal ores?
Carbon is commonly used to remove oxygen from metal ores through a process called smelting. The carbon reacts with the oxygen in the metal ore to form carbon dioxide gas, leaving behind the pure metal.
How can metal or ores be removed from the ground?

What are factories that make metal ores called?
Factories do not make metal ore. A refinery or smelter makes metal from metal ores.
How are sulfide ores turned into oxides?
Sulfide ores can be turned into oxides through a process called roasting, where the ore is heated in the presence of oxygen. This causes sulfur in the sulfide ore to react with oxygen and form sulfur dioxide gas, leaving behind metal oxides. The metal oxide can then be further processed to extract the desired metal.
Does metal come from ores?
From various minerals and ores which are mined. Which metal depends on which mineral is mined.
The process of transferring the cost of metal ores and other minerals removed from the earth to an expense account is called?
The process of transferring the cost of metal ores and other minerals removed from the earth to an expense account is called depletion. This accounting method allows companies to allocate the cost of natural resources over time as they are extracted and sold.
What metal ores are categorized in SIC 1099?
Metal ores included in this category include: aluminum, antimony, bastnasite, bauxite, beryl, beryllium, cerium, cinnabar, ilmenite, iridium, mercury, microlite, monazite, osmium, palladium, platinum, quicksilver, the rare-earth metals, rhodium.
Are vein minerals metal deposits that occur in cracks in rocks?
Yes and No, while some metal ores may indeed be vein minerals, not all vein minerals are metal ores and not all metal ores are vein minerals.
How is iron usually separated from its ores?
Iron is usually separated from its ores through a process called smelting, which involves heating the ore with a reducing agent such as coke. This process removes the oxygen from the ore, leaving behind the pure iron metal. The impurities in the ore combine with the flux to form a slag that is then removed.
The process of transferring the cost of metal ores and other minerals removed from the earth to an expense account is called what?
The process of transferring the cost of metal ores and other minerals removed from the earth to an expense account is called depletion. This process allocates the cost of natural resources that have been extracted and helps to accurately reflect their diminishing value over time.
