Thinking of melting copper pennies but need some

I've already found a decent way of acquiring thousands of dollars in pennies and sorting them the problem is i have to melt them into bars in order to sell them to scrap metal shops for cash, melting and casting them isn't a problem but what is a problem is the alloy, copper pennies use zinc and sometimes tin to the tune of about 95% copper 5% other shit, does anyone know if scrap Get price

A Poor Man's Method of Smelting Gold

This will cause the lead, copper, or zinc in the mixture to come to the top. Pour off the slag into a heat resistant container. The liquid will be too thick to pour once it is cold. Add in some borax to thin out the liquid. When the liquid cools, chip off the glass — which will have floated to the top during the cooling process — and there Get price

Refining Gold Jewelry Scraps

The process is particularly suited for treatment of low karat gold scrap, since large additions of copper or silver are unnecessary to achieve the desired 25 percent-or-less gold content. On the contrary, this process may not be as desirable for an operation making predominantly medium to high karat gold jewelry, as scraps from production may Get price
