Lead antimony removing from lead process plant

Feb 23, 2021

In order to solve the shortcomings when removing lead from crude antimony in the traditional antimony smelting, a new process was provided using NaPO3 as lead elimination reagent to yield phosphate slag, and it was removed by floating on the surface of the liquid antimony. Reaction mechanism was clarified by using the TG-DTA and XRD techniques

If you're casting for center fire, then you need to alloy with some tin and antimony. You can get both of those from wheel weights. My magic mixture is 7lb pure lead, 7lb wheel weights, and 1/4lb 63/37 tin/lead
