Gangue-

In mining, gangue(pronounced "gang") is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed.

When oxygen is blown into pure iron to remove impurities Wont it react with Iron itself to give iron oxide?

Oxygen is not blown into pure iron, it is blown into molten iron ore (many impurities) and coke has been added to the mix as well. the coke reacts with the impurities and the oxygen to purify the iron ore.


Which metal ore do you m ine to extract steel?

Iron ore is the metal ore mined to extract steel. Iron ore is a key raw material used in the production of steel through a process called smelting, where the iron ore is heated with coke and limestone in a blast furnace to remove impurities and create steel.


What type of chemical reaction is always involved in the extraction of metal from its ore?

The extraction of metal from its ore typically involves a reduction reaction, where the metal oxide in the ore is reduced to the elemental metal using a reducing agent such as carbon or hydrogen. This reduction reaction is necessary to separate the metal from the impurities in the ore.


What is the name given to the extraction of copper using a furnace?

The extraction of copper using a furnace is called "smelting." In this process, copper ore is heated in a furnace along with a reducing agent, such as carbon, to separate the metal from its ore. The heat causes the copper to melt and separate from impurities, producing molten copper that can then be refined further.


How is diamond ore processed into purified mineral?

Diamond ore is crushed and sorted into different sizes before further processing. The ore is then crushed, washed, and treated to remove impurities. Finally, the purified diamond mineral is cut and polished for use in jewelry or industrial applications.

What is the process called when removing impurities from Iron Ore?

The process is called smelting. It involves heating the iron ore in a furnace with a reducing agent such as coke (carbon) to remove the impurities and extract the pure iron metal.


How did iron extract from the ground?

Smelting: Mined out of the ground, raw ore is a mixture of materials called ore proper and loose earth called gangue (waste). The ore proper is separated by crushing the raw ore are simply washing away the lighter soil. Breaking down the ore from its impurities is more difficult.


Which substance is formed when impurities in the ore react with calcium oxide?

When impurities in the ore react with calcium oxide, they form slag. Slag is a byproduct of the smelting process and is used to separate impurities from the metal being produced.


Is iron ore homogeneous?

no because it contains impurities


How do you separate metal from the ore?

Metal can be separated from ore through a process called smelting, where the ore is heated to high temperatures, causing the metal to melt and separate from the impurities in the ore. Chemical processes such as leaching and electrolysis can also be used to separate metal from ore by dissolving the metal and then extracting it.


How do you get lead from ore?

Lead is typically extracted from its ore through a process called smelting. The ore, usually galena (lead sulfide), is heated with a reducing agent, such as charcoal, in a furnace. The lead is then separated from the impurities and collected as a molten metal.


What impurities are present in iron ore?

Common impurities found in iron ore include silica, alumina, phosphorus, and sulfur. These impurities can affect the quality of the iron produced during the smelting process and need to be minimized through various beneficiation techniques.


What is an ore that is mixed with other substances and then melt to separate the useful metal from other elements the ore contains in the process?

The ore is mixed with other substances to form a mixture called a slag. This slag is then melted to separate the useful metal from other elements present in the ore through a process called smelting. The impurities in the ore combine with the slag, allowing the pure metal to be extracted.


How do you extract tin from it's ore?

Tin can be extracted from its ore, cassiterite, through a process called smelting. The ore is heated with carbon in a furnace to separate the tin from the other elements. The tin melts and can be collected as it is denser than the impurities.


What type of resource is iron ore?

Iron ore is a natural resource that is a key raw material in the production of iron and steel. It is primarily used in the manufacturing industry for making steel products such as machinery, vehicles, and infrastructure.


How is metal produced from ore?

Metal is produced from ore through a process called smelting, where the ore is heated in a furnace with a reducing agent such as carbon to extract the metal. The metal is separated from the impurities in the ore and then further processed to obtain the desired purity and form. This process varies depending on the type of metal and ore being used.


How is tin metal made from the ore?

Tin metal is extracted from its ore, cassiterite, through a process called smelting. The ore is heated in a furnace with carbon to reduce the tin oxide to metal. The molten tin is then collected and purified to remove impurities.
