How can I convert Raw Sugar to White Sugar?

Question by Jonelle A: How can I convert Raw Sugar to White Sugar?
I have Raw Sugar that looks like it is in its crystal form. And it is still brownish looking. And I would like to make it into normal white sugar. Should I put it in a blender or food processor? Or how to use it. I am trying to make a cake. (Banana Cake.) Or How do I use is it in place of white Sugar? How can I use it. This is the recipe I am using.
