There are several ways to do this. The most common is smelting, a favorite of mine is bioleaching.

Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
Do metals only come fron ores?
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
Is zinc produced?
Yes, zinc is produced by extraction from ores.
How do you make semi-metals?
Semi-metals, also known as metalloids, are typically made through a process called doping. This involves adding small amounts of impurities to a pure semiconductor material, such as silicon or germanium. The impurities alter the electronic properties of the material, making it exhibit characteristics of both metals and non-metals.
Which metals are extracted from their ores by thermal decomposition?
siliconMagnesiumIronNickelCopperGoldSilver
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)
What is meant by metallurgy?
Extraction of metals from its ores and formation of ores. Studying their properties, their alloys,refining of ores.
Does sulfur have ores?
yes , sulphur have ores. such ores are called sulphide ores. these sulphide ores are purified by the process called roasting. this is the process which involves heating with oxygen and then reducing into original metals. eg: copper sulphide, zinc sulphide, etc.
What is smelting process?
A process of melting and decomposing ores to separate the metals they contain.
Are metals are found in rocks called ores?
Yes metals are found in rocks called ores. Most metals are more reactive and are found combined with other elements in rocks.
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.
What is Pyro metallurgical process?
The word pyro metallurgy comes from two words=pyro+metallurgy where pyro means heat and metallurgy means extracting metals from their ores ,purifying and modifying the metals for use.So Pyro metallurgy is the process of extraction of metals from their ores and their purification with the application of heat.following is the list of pyro metallurgical processescalciningroastingdryingsmeltingrefiningExamples of elemnts extracted using pyro metallurgical processes are Fe, Cu, Zn, Chromium, Tin, Manganese.
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.
What are rocks called that contain metals that can be mined for profit?
They are called ores.
Which process is the key concept behind smelting metals from ores?
Partial melting
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 do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
