metal recycling

[MBG]

who does it here?

[MBG]

like a mill of some sort?

[Redline]

I do!

Same here.

The wife calls it junk and I call it future projects. What I don't need goes to the recycler and the money goes toward more pieces for the project. A never ending cycle.

I recycle as much as possible in the area of Non-Ferrous Metals.

I have an arrangement with a large PC dealer that averages close to 50 dead Hard Drives per month... The drives are stripped to the chassis (to be melted for the Aluminum), the Magnets (for welding fixtures and other uses), the platters are being stock piled for reflective surfaces, though the tin and Circuit boards return to the refuse stream...

Recently I did a labour exchange with a scrap yard where I provided some computer skills they needed and I got 2 truck loads of BBQ shells for Alum and close to 100lbs of analog cable TV distribution housings (all top quality castings of Alum alloy)

All Copper based alloys are also stripped and sorted into piles for brass/bronze alloys.

Ive processed or stripped as many as 5 briggs & Stratton lawn mower motors at once (though find that it is dirty and tedious).

I stock-pile bed frame rails (angle iron) or any type of steel pipe for numerous welding projects, and the land-fill is over-running with this stuff.

This largely out of nessecity as I don't know of any metal suppliers locally in my area (Eastern Ontario) and the price is negligible ( less transport and time).

Scrap Alum is currently about $1/lb Canadian arround here.

wow they give me .17 a lbs for chips of aluminum

I just wanted to know the process they do it

[FrankG]

Alum Chips are a bit different in value for a couple of reasons... It may be a mix of other shop swarf that lands on the floor, but probably more because Alum oxidizes immediately upon contact with the air... so chipps will have a greater surface area to volume ratio than say a lawn mower motor for a given weight of material.

Then the Alum gets melted the oxides are formed into the Dross or Alumina impurities that have to be skimmed from the melt and are typically just waste material...

If your a keener, the Alumina Dross can be refined for use as a refractory material for use around the foundry.

so you can use it for casint aluminum?

[FrankG]

I wouldn't melt shop sweepings, I think even pop cans would yield more metal... Almost 50% loss due to oxides and crud from the paint on the cans. My guess is less than 40% of the weight would be recovered...

a tremendous wate of energy...

how are they shop sweeping if they come off of a machine and into a bucket?
