What does it mean when ores may need to be concentrated before the metal is extracted?
And also, how would you be able to identify the chemical formula of a compound using the data sheet AQA gives you?
Any help would be appreciated,

Thank you.

Hiya, when an ore is concentrated all of the waste material that doesn't contain the ore is removed e.g. rock, sand. This means that the ore left contains a higher percentage of ore than it did before so economically it is more valuable. However the downside is the waste rock must be disposed of, which because of its size is bad for the environment.

Thank you, I understand it now! Also, do you know why alkanes are known as saturated hydrocarbons? It says something about it having the most possible hydrogen atom in each molecule? What does that mean?
