1. A method for recovering solder from solder coated scrap pieces, comprising the steps of:
containing a quantity of solder coated scrap pieces within a centrifuge receptacle of a first centrifuge, the centrifuge receptacle has perforation holes and is rotatably mounted about a first centrifuge axis, a solder collection container surrounds the centrifuge receptacle; heating the solder coated scrap pieces and melting the solder thereon with a heater surrounding the solder collection container; and with a drive system, rotating the centrifuge receptacle while the first centrifuge axis is in about a horizontal position at a low speed and tumbling the scrap pieces along a longitudinal length of the centrifuge receptacle, and later rotating the centrifuge receptacle at a high speed for centrifugally extracting molten solder from the centrifuge receptacle, radially outwardly through the perforation holes into the solder collection container. |
