Borax and flourspar consume graphite crucibles very quickly, I noticed new method to metalize E-waste ash used in Indonesia, with this method we can start chemical PM's recovering after collecting the metals shots or we can remelt them to make copper anode without consuming a lot of crucibles.

By this teqnique I think we can process large e-waste quantity in short time, I didn't test it, looking for members thoughts about it.
In this video they just use steel cone, but I watched other videos using clay pot with a small hole in the bottom of it,and others use steel cone built with refractory material, but the idea is same, after they mix E-waste ash with borax and soda ash,they fire the steel cone with charcoal and air blower then start to add ash, after ash melted it collected from the water bucket under the cone, charcoal with good air source can reach 1300 c temperature, so we can make sure that all E-waste particles will be melted
