Zinc in Lead The High Road
Sep 06, 2008 At 7872 F zinc melts Lead melts at 6215 F I melted the wheelweights over my Coleman stove and pore my ingots Some looked weak and 2 even broke Malleability was not there If I do have a zinc contamination can I separate the zinc from the lead by remelting the ingots at a temperature above 621 but below 787? I am using a bottom pour (Lee Oct 02, 2009 Zinc, lead, and tin do not alloy well, lead will unite with only 16 per cent of zinc, and above that proportion the metals are only mixed when melted, and on cooling partially separate Sufficient lead having been melted in the pot, about ½ pound of lump sulphur, broken into pieces about the size of hickory nuts, is added, and the whole well A possible way to remove zinc from molten leadNov 10, 2014 Wheel weights seperating zinc from lead?

How does one separate Wheel Weights? Ruger Forum
May 12, 2015 Since lead is more dense than either steel or zinc, the steel and zinc weights will float in melted lead If you want to do a quick presort before melting, drop them a short distance onto a concrete floor; the lead weights will make a dull "clunk", the steel weights will ring (like dropping a wrench on the floor) and the zinc weights will make Jul 25, 2019 To keep the zinc separate, molten lead is introduced into the chamber The zinc then dissolves into a molten state and gets carried to another chamber to cool Refining The zinc molten, which is cooled to 824 degrees Fahrenheit, can be further purified by Zinc: Learn How To Trade Industrial Metals at CommodityThe zinc tailings pass over a Wilfley Table which gives the operator a constant, visual picture of the efficiency of the zinc flotation machine, and also recovers additional zinc values Zinc concentrates are fed to a Wilfley Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a ThickenerHow to Process LowGrade Lead Zinc Ore by Flotation
