What is it called when the iron ore is reduced?
It is called Spong Iron also as Direct Reduced Iron (DRI)
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 removed when a ore is reduced by carbon?
When an ore is reduced by carbon, oxygen is typically removed from the ore. This process, known as reduction, involves the carbon reacting with the oxygen in the metal oxide, resulting in the formation of carbon dioxide or carbon monoxide, and leaving behind the pure metal. For example, in the reduction of iron oxide (Fe2O3) using carbon, iron is produced while carbon dioxide is released.
What is iron ore lumps and iron ore fines. What is the difference?
· Iron ore fines (less than 6mm) · Sized ore (size 5mm to 20mm) · Lump ore (size 10mm to 40mm) Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore. The reason lump is preferred is that when it is fed into a blast furnace for steel-making, its particle size allows oxygen or air to circulate around the raw materials and melt them efficiently. The fine iron ore products have first to be processed into what is called sinter, otherwise it will effectively smother the air flow in the blast furnace.
How is oxygen removed from metal ores?
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 features do geologists look for when they prospect for ore?
Geologists prospect ores by looking at their shape, size, color and how hard it is. They also need to find what is inside the ore or else they will not know what kind of ore it is.
What is used to crush gold bearing ore?
A Jaw crusher is one of several types of instruments used depending on the size and tonnage of the ore.
What Instrument is used to crush gold bearing ore?
A Jaw crusher is one of several types of instruments used depending on the size and tonnage of the ore.
What is a reduced-size liver transplantation?
Reduced-size liver transplantation is the replacement of a whole diseased liver with a portion of a healthy donor liver.
What is a beneficiation?
A beneficiation is the reduction in size of particles of ore before further processing.
