Sorting is the critical first step in scrap metal processing — separating ferrous from non-ferrous metals, then further dividing each type into its specific grades. At a commercial scale, sorting uses magnets (to pull ferrous metals), eddy current separators (to eject non-ferrous metals from mixed streams), density separation, and hand-picking. For customers bringing scrap to endless metals in Auckland, sorting your material before arrival is the single most effective way to maximise your payout. Keep copper separate from brass, aluminium separate from steel, and remove non-metal attachments where practical. A few minutes of sorting at home can mean a significantly higher grade — and a bigger payment — at the weighbridge.
