I find myself in a bit of a dead end. Perhaps if you have the time and will you'll try to help me.
I have a quantity of aprox. 60 kg of AgPd contacts and the support is made of alpaca alloy(Cu-Ni). I have been trying to dissolve the alpaca in H2SO4+ H2O2 solution but it works very hard and it uses a lot of H2SO4. For example for 1kg or 2.2 lbs I used roughly 8 litres or almost 2 gallons of acid. The contacts are aprox. 9-10% of the total mass.
Any ideas would be greatly appreciated.
