The word "smelting"

Well, I will get even more nitpicky. I feel entitled to since I am a metallurgical engineer and accurate terminology is critical to safety, technical viability and economic success.

"Smelting" isn't extracting a metal from an ore. It is using pyrometallurgy (heat, fire) to extract a metal from an ore (or concentrate).

When you run copper ore through a reverb furnace, tap matte into a rotary converter and oxidize to copper metal, that is smelting.

When you run copper ore through a pressure leach autoclave, do solvent extraction on the resulting solution to obtain a purified copper solution and then electrowin copper, that is NOT smelting. That is called "recovery" or "refining."

I have this problem all the time at Trail Operations. People will call the zinc refinery a "zinc smelter." No, we have a lead "smelter", and we have a zinc "refinery." There are plants that do zinc smelting, but not in Trail (Trail uses the roast-leach-electrowin, or RLE, process for zinc).

Again, technical accuracy is important.

If you are fixing a car, there is a big difference between "radiator" and "heater core." They both ultimately function like radiators, but they are definitely not the same thing. See what happens when you take your car to the mechanic and tell him to replace the radiator (oh, but you "meant" heater core).

If you are building a house, there is a big difference between "drywall" and "cement board" even if the same guys are installing both. If you go out and ask for someone to "drywall" your bathroom shower, you might get some very bad results.

Peace.

PS. and for "smelting lead" - if you are doing that in your back yard, you are potentially killing yourself and all your neighbors from sulfur dioxide poisoning. If you are "melting" wheel weights, at most you make a little localized lead fume, assuming you are overheating it like crazy.

Pretty much say's it, I think
 
...and it's still just melting lead no matter what you call it. :)

The improper use of the word "smelting" by bullet casters probably originated on the Cast Boolits forum. It is the term they use for melting dirty lead to separate contaminants - such as wheel weights, lead with rubber or paint coatings, etc - and it is almost correct in that context, but not quite. Every level of language police from Grand-Poobah to Grade-Three-Dropout has told them they are stupid, dangerous, anti-American, and acting against God's wishes... but they keep doing it anyway. Because they know what they mean and they don`t give a crap. :)

The silly thing about the English language is that if enough people use the "wrong" word, it becomes the "right" word. We don`t have to like it but we can`t do a dam thing about it, either.
 
Language police rein supreme in this thread.

Say it again, in my layman term when I smelt lead that mean melt down WW, ... , into ingots.
casting bullets is melting down ingots, ... , into bullets.
... are the minor steps that bullet castor knows to do.
