Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
How are the very reactive metals high up in the reactivity series extracted from their ores?
reactive metals can often be extracted by electrolysis where there ore is disolved into a solvent and an electric current is passed through.
Why are lead and zinc connected?
The production of these base metals became closely intertwined because both were extracted from the same ores--although in different proportions.
Are transition metals often found in ores?
Quick and simple answer is that metals are solid and therefore are affected by the gravity of the Earth more than gases. Therefore gases are in the air and solids are on the surface or under the surface of the Earth.
Do metals only come fron ores?
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
Where are metals extracted from?
Metals are extracted from various ores that are mined from underground.
What are the important ores?
Their importance is that these ores can be extracted into metals .
Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
How are minerals extracted from their ores?
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
A mineral with a valuable metal in it is an?
All metals come in a Raw form and are extracted from rocks that are called Ores
What does metallurgy mean?
metals are extracted from their ores based on several physical processes and several chemical processes.
How are the very reactive metals high up in the reactivity series extracted from their ores?
reactive metals can often be extracted by electrolysis where there ore is disolved into a solvent and an electric current is passed through.
Why metals and their ores are so important to mankind?
Many of the metals that humans use come from ores. For example the iron used to make steel comes from the the mineral hematite, lead for batteries is produced from galena, and the magnesium used in vitamins comes from dolomite. Ores of these useful metals must be extracted from Earth in a process called mining.
Why slag is produced in metal extraction?
Metals are extracted from their ores which contain several impurities, the lighter impurities are removed by slag formation.
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.
Why are lead and zinc connected?
The production of these base metals became closely intertwined because both were extracted from the same ores--although in different proportions.
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.
