## Recycling Metals

I was looking around the other night for information on how to separate metals through smelting, electrolysis, etc. I wasn't able to find much. I'm guessing this is still somewhat out of the range for the DIYer?
My neighborhood typically has a rediculous amount of scrap metal on the curb, but the scrap yards around here only offer a slight profit on pure metal. Besides selling the metal at a scrap yard, how hard would it be to seperate the metal yourself, and just use it for your own purposes. I'm going to be investing in a metal-working lathe in the near future, and I'd rather reuse metal I've got lying around than buying it brand new at a premium. What do you guys think, is this doable?

- Get metals necessary and weight out in the same ratios

- Bake until melted...

- Now it's just like cooking deadly and inedible pancakes...

To find out more about classifying mostly pure metals an easy way of doing it could be through density...

You'd need an accurate measuring item, like a beaker marked in mls

Along with that you'd need some pretty accurate scales

Weigh your chunk of metal, to the milligram, for smaller amounts at least one decimal place is a must.

add a very exact amount of water to your measuring jug, drop the metal in and record the change, that difference in mls is the difference in cubic cm, you can now work out density by using the formula: D = M/V

to you that's density = mass divided by volume

so 100g/cm

^{3}would be = 90g/0.9cm^{3}To convert to cm

^{3}is nice and easy if you have the measure in millilitres...Once you have a good density you can look up the index of metals and check their density to find your match. You should repeat the tests three times to try and get the most accurate measurement possible...

You could find out the atomic weight and use a periodic table but that would be doing extra maths for nought.
