Processing Your Scrap - The moment your scrap shipment is weighed in at our refining division, it is entered into our computerized refining flow system. The shipment is checked and double-checked through every step of the refining process. Each lot, regardless of size, receives the same careful attention to ensure you a maximum return.
It is essential for your material to be properly melted before assay. Clean scrap is mixed with a special flux which makes the melt more fluid and homogeneous. Our experienced processors will ensure that the optimum flux mixture and melting technique is used.
The melt is poured into a mold where the metal settles to the bottom and the slag created by the flux remains on top taking some of the non-metallic impurities with it. The bars are then returned to our vault to be weighed and sampled, where they will remain until you have been paid for your scrap.
