What factors determines the method used to extract a metal?
The method used to extract a metal is determined by factors such as the reactivity of the metal, its abundance in the Earth's crust, and the cost-effectiveness of the extraction process. Additionally, the physical and chemical properties of the ore from which the metal is extracted also play a role in selecting the extraction method.
What is Balbach-Thum process?
The Balbach-Thum process is a method used in metal refining to extract gold and silver from ore. It involves melting the ore with lead to form a lead-silver-gold alloy, which is then treated to separate the precious metals. The process is known for its efficiency in recovering gold and silver.
Why is it sometimes not economically viable to extract a metal?
Sometimes extracting the metal would cost more than would be economically beneficial, either because of where it is located, the process that would need to be used to extract it, or other reasons.
Why carbon is used to extract lead from lead oxide?
Carbon is used to extract lead from lead oxide because it acts as a reducing agent in the smelting process. When carbon is heated with lead oxide (PbO), it reacts to form carbon dioxide (CO2) and lead (Pb), effectively reducing the lead oxide to elemental lead. This process is thermodynamically favorable and economically viable, making carbon a practical choice for extracting lead in metallurgical operations.
Why is electrolysis used to extract certain metals?
Electrolysis can be used for the following purposes:Electroplating a baser metal with a more attractive metal. e.g. electroplating brass with goldRefining of impure metals. e.g. to remove impurities from copperElectrometallurgy - to extract metals from their compounds

What method is used to extract magnesium or aluminium from their ores?
Electrolysis is used to extract magnesium from its ore, while electrolysis or a chemical reduction process is used to extract aluminum from its ore. Both processes involve passing a large electric current through a molten compound containing the metal ions to separate the metal from its ore.
What is Balbach-Thum process?
The Balbach-Thum process is a method used in metal refining to extract gold and silver from ore. It involves melting the ore with lead to form a lead-silver-gold alloy, which is then treated to separate the precious metals. The process is known for its efficiency in recovering gold and silver.
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.
What method to be use to separate powdered iron and powdered aluminum?
Iron is a magnetic metal, aluminium is not.So, a simple method is to use a magnet for this separation.Magnetic separation is frequently used to extract iron from wastes.
How can carbon be used to extract a metal from its ore?
Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with carbon or by electrolysis.
Describe the method of purification of copper?
The method used to extract Cu from its ore depends on the nature of the ore.
How do you extract a metal using carbon?
To extract a metal using carbon, the metal ore is mixed with carbon and heated in a furnace. The carbon reacts with oxygen in the metal ore to form carbon dioxide gas, leaving behind the pure metal. This process is known as reduction and is commonly used to extract metals such as iron and copper.
Describe the process used to extract metal from hematite ore?
go do it youself! :)
Name three general methods for extracting a metal from its ore?
The three method generally used to extract metals from ores are dependent on their reactivity. The first method is electrolysis, which is used for metals like aluminum and magnesium that have a high reactivity. The second is extraction by reaction with either carbon or carbon monoxide, which is used for less reactive metals like iron, lead and zinc. The third and final method is the use of hydrogen and this method is used for unreactive metals like gold, silver and copper. The third method is used in a variety of ways as many of these metals don't need to be separated from their ores but chemical reactions may be required to remove other contaminant materials.
Why is carbon used to extract metal from ores?
Carbon is used to extract metal from ores through a process called reduction because carbon is a strong reducing agent. When carbon reacts with metal oxides in the ore, it removes oxygen from the metal oxide, leaving behind the pure metal. This process is known as smelting and is commonly used for extracting metals such as iron from their ores. Carbon's high reactivity and abundance make it a cost-effective and efficient choice for metal extraction.
What is the name of the method where plants are used to extract metals from soil?
Phytomining is the method where plants are used to extract metals from the soil. This process allows the plants to absorb metals through their roots, which can then be harvested and processed to extract the metals. It is an environmentally friendly method that can be used to recover valuable metals from low-grade ore deposits.
