cementing gold and copper

[jimmyreece]

if was to cement copper on to a piece of iron, whats going to keep the gold from cementing on to the copper?

 

[butcher]

nothing, all metals below Iron will cement.

cement gold using copper buss bar, after gold is removed (stannous chloride test), then cement copper with Iron.

read up on reactivity series of metals, google search.

of course, start from the bottom then work your way up.makes much sense.
thanks butcher for hangn in there with me. this all comming to gether much easier now. bottom line is you cant cut no corners, cant rush none of it. and read untill all this makes sense.
i have close to 5 oz in precipitated powder im waitng to smelt. never thought i would get this far....for a moment anyway

I think you mean melt, not smelt.

One does not "smelt" precipitated powder. Smelting is the act or extracting elements from ores by heating.

You have close to 5 ounces to melt.

Posted comments before taking notice that Ralph beat me to it. Good catch, Ralph.

corrected misspelling, thanks to Claudie.

with all the slag and copper that ended up being mixed in the powders, i unkowing was using the right word "smelt"
next time i hope to "melt"my gold and not "smelt" it !

Heh! Nice try, but, no, you're still melting. Melting various elements (alloying) doesn't change what you're doing.
Now if you were melting (smelting) those metals in the way of oxides and/or sulfides, along with gangue (the native material in which the metals are found), yes, you would be smelting. Key here is that smelting alludes to the extraction of metals from ore.

understood. thank you

the way I understand the smelting process seems to me to be very similar to a chemical reaction, flux formula and high temperature chemically reacting to bring valuable metal from ore, usually oxidizing base metals in slag glass.
