depends on which metal, and which ore. Most are crushed- then some are roasted (heated) some are separated by weight, physical characteristics, etc. In some cases, metals are recovered by chemical reaction, using a chemical that dissolves the metal, which removes it from the waste material.

What are the differences between pure metals and alloy metals?
they are different in many ways eg they are shinier
Is There are two different ways to number the groups of the periodic table?
Metals, Non-Metals and the ones that are both. :)
What are the many different ways elements on the periodic table are classified?
1.metals, semi-metals, non metals 2.Solid, liquid, gas 3.Conductors Semi-conductors Insulators
Why do different metals react in different way and with different speed?
The way of reaction depends on its type, and the metal. As for the speed, there are different ways to increase or decrease reaction rate(temperature, catalyst.)
Ways to identify metals?
Check
What ways are pure land and zen Buddhism different?
I personally don't think they are very similar. IIRC, Pure Land emphasizes a literal "Pure Land" that you may go to upon death. Compare to Zen, where the goal is nothing, you are already there..
How do you identify a gold necklace?
Different countries have different ways of marking gold and silver objects. In the UK objects made of these metals are assayed by the government and stamped with an assay mark.
If a substance is an element is it a pure substance or a mixture?
There are two ways to think about this. Chemically, the element is a pure substance (each atom has the same number of protons). Nuclear speaking, the element may be represented by a number of different isotopes (different number of neutrons).
In what 2 ways can elements occur in nature?
An element can be created in a particle accelerator or fusion reactor. It can also be "made" by waiting out the half-life of an element further down on the periodic table.
Will metal get affected in sugar water?
yes, some metals will rust in various ways and at different speeds. However only metals with iron in them will rust. Other metals will either oxidize or just remain the same. So the answer is partly yes, partly no. It depends what metal specifically.
How many ways of making metals?
by electrolysis by thermal reduction
What is an alloy and why is it good to use in a pratical?
An alloy is a mixture of metals (or metals with other elements such as carbon). Why you might use them in a practical depends on what you are trying to find out. It would be unlikely that you would use them in simple chemical reactions as you usually want pure substances for that. I wonder if you mean why are they good for practical applications? They often behave in different ways from their constituents and these behaviours make them useful. For instance a mixture of lead and tin melts very easily so it's used for solder. Steels are alloys of iron with carbon and other metals and can be made with a wide range of useful properties.
