What else can I help you with?
Is extraction of metal is thermodynamically stable?
The answer to this is , No! The extraction of metal usually requires the appliction of heat to separate the metal from it's matrix, the stuff mixed with the metal. This is called "Smelting". Each metal melts at a different temperature. Some of these temperatures are very high, so great care must be taken in this process.
What was the name of the metal produced by early metalsmiths?
The metal produced by early metalsmiths was likely copper, due to its malleability and ease of extraction from ores.
When is electrolysis used for extraction?
Electrolysis is used for extraction in processes where a metal is extracted from its ore using electricity. It is commonly used for the extraction of reactive metals like aluminum and sodium from their ores. The process involves passing an electric current through a molten or dissolved salt of the metal to break it down into its individual elements.
What kind of pollutant is Mercury Classified as?
Mercury is a metal that is liquid at room temperature. It is also poisonous.
How do you obtain aluminums element?
Aluminum is obtained through the extraction of bauxite ore, which is the primary source of aluminum. The extraction process involves refining bauxite into alumina through the Bayer process, followed by the electrolytic reduction of alumina to produce aluminum metal.
Why slag is produced in metal extraction?
Slag is produced during metal extraction as a byproduct of the reaction between impurities in the ore and the flux added to extract the desired metal. The slag, which consists of non-metallic compounds, forms from the impurities that are removed during the smelting process. It helps to separate the impurities from the metal being extracted.

How is electrolysis used in the extraction of metal from its ore?
Electrolysis is used in the extraction of metals from their ores by passing an electric current through a molten or dissolved metal compound. This process causes the metal ions to gain or lose electrons, resulting in the deposition of pure metal at the electrode.

It is commonly used for the extraction of reactive metals like aluminum and sodium from their ores. The process involves passing an electric current through a molten or dissolved salt of the metal to break it down into its individual elements.
Most metallic ores are produced by which two types of processes?
Most metallic ores are produced through mining and extraction processes. Mining involves the physical extraction of ore from the earth, while extraction processes such as smelting, leaching, or electrolysis are used to extract the desired metal from the ore.
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.
The most toxic metal pollutant of the automobile exhaust is?
The most toxic 'metal' pollutant would be lead.Other pollutants present in the automobile exhaust are:HydrocarbonsNitrogen oxidesCarbon MonoxideCarbon Dioxide
Separating useful metal from other elements is called?
The process of separating useful metal from other elements is called metal extraction or metallurgy. This process involves various techniques such as smelting, leaching, and electrolysis to isolate and purify the desired metal from its ore.
Is corrosion reverse of metal extraction?
Type your answer here... most of the metals naturally exist in combined formed during metallurgy the metals are extracted from their ores by reduction process in pure metallic state, metals are unstable and considered to be in the excited state.therefore,the extracted metals have a tendency to go to thermodynamically stable state , which is otherwise known as corrosion.
What is the difference between isolation an extraction?
Isolation is the process of the seperation of the two metals but extraction is the process in which we get the desired metal from the concentrate.(in general we can say from the minerals and ores)
After miners remove ore from a mine what process removes the metal from the ore?
After the ore is removed, the process of extraction involves crushing and grinding the ore to separate the valuable metal from the waste material. This is typically followed by a process such as smelting or leaching to extract the metal from the ore. Finally, the metal is refined to ensure purity and quality.
