I want to dissolve iron scraps electrolytically; that is turn them
into Fe++ for easy disposal.

I want to use Sulfuric acid as electrolyte.

What voltage DC should I use per Kg of Iron, and would graphite be OK
for one of the terminals?

It is environmentally very unlucky way to dispose iron and cannot
be recommended.

Btw, it cca 3 400 000 C/kg, i.e. cca 960 Ah/kg, so about 2-3 kWh/kg.

Considering price of electricity and acid ( almost 2 kg of pure
acid per kg of iron )
it would be very expensive disposal, aside of the fact you replace
one type of waste by much worse waste.

Additionally, you would have to implement prevention against
hydrogen explosion.

Why don't you sell them as scrap iron? You won't get very much for them.

Dissolving them electrolytically will cost you a lot of money.

Thank you. Luckily we found a drum reconditioner to take away all our
old drums. and plastic ones too. It's hard to dispose of them these
days because imports are displacing manufacture.

No one would take our empty 200L steel drums. The demand for them
these days is minimal. The Greenies authorities want every single
drum rinsed out thrice, then crushed to a pancake for recycle at the
steel works. It all costs money, lots.

We were desperate and were considering two options:

1/ Electrolytic oxidation.
2/ A pure-oxygen reactor to burn them.

Luckily a rag-and-bone man was interested and took them all away for
free.
