Abstract: The invention is a method of separating metals such as zinc, lead and cadmium from iron in secondary feed stocks such as EAF Dust, BOF Sludge, mill scale, iron fines, tire dust and other iron and zinc containing residues and dusts. The method includes the steps of reduction roasting the feed stocks at a volatizing temperature sufficient to volatilize the zinc and other metals into metal fumes but insufficient to volatize iron and then collecting the metal fumes as a metal dust. The metal dust is then leached with a leaching liquid to form a leach liquor and a leach residue. The leach liquor is then purified by zinc dust cementation to form a purified liquor and a zinc dust cement residue. The purified liquor is then separated from the zinc dust cement residue, and a zinc recovery step is then performed on the purified liquor.

The method includes the steps of providing a hobble cord having opposite first and second ends and a plurality of loops. The loops of the cord are preferably preformed onto the cord and are integral thereto. Each loop formed on the cord has a loop opening dimensioned to receive one end of the cord. The first end of the cord is first threaded through the ring and the ring is then positioned to sit adjacent one of the loops between the loop and the first end of the hobble cord. The first end of the hobble cord is then threaded through the opening of the loop. The ring is then firmly secured to the cord by pulling the cord all the way through the loop. The steps may be repeated to attach more rings to the cord in succession.
