Everyone seems to be looking for an answer im not sure if this one im just thinking off the top of my head.
first of all No I repeat copper bronze weapons unless we live in a time period that doesnt have better metals if we have better metals then they would be used in smithing of weapons&armors.
However there would still be simply bronze copper tin items that could be made to gain smithing experience such items would be basic fluff adornments and such im sorry but i have smithed before in real life and understand a little about it.
Also I have a feeling that dwarves will be the best people suited to the tasks of smithing but not the only ones.

Iron I believe should be the first that you make weapons and armors out of
some of the items needed for this furnace, anvil, hammer tongs, apron, gloves, buckets of water ,forming casts ,as well as the metal itself and bellows,salt
it wouldnt be a click click system but would go on percentages % of your smithing ability that would raise as you went up levels.You could smith more and more as you got better and better .
Here is the basic way you would smith using the ore in the furnace you would begin refining the ore (this would take a bit of time )while doing this you work the bellows make sure theres plenty of logs and such to keep the fire going (giving jobs to loggers)(as well as having a job for apprentices you might take on in the future)You know the abled body people that nothing is wrong with them but they got no money or way to make it )anyways keeping the fire hot you would melt down the ore or ores more ores making bigger bars that you would pour the molten liquid into the bar casts (then letting it cool)while there cooling from you pouring them in or an apprentice you would have leisure time to work on other bars you have already made also you could have the apprentice keep runnign the bellows and keeping the fire good and hot while you smith ,anyways you would then take the bar whatever size or bars and using the tongs place it into the coals letting it heat while pulling it back out and beating a shape with the hammer plunging it into the buckets and back out oh and buckets of sand too .
Now there would be a chance for success while making these items and a chance for failure but for basic items and such if you failed and noticed it you could simply reuse the metal smelt it again.
Now with regards to enchanting you would go through the same circles however there would be different powders,dust,potions,and spells needed as well as very high smithing lvls
different items would need different things to make them work
perhaps also there could just simply be enchanting potions you smith the metal or have someone smith it for you pour on the potion and cast the spells into it or use different items to make the same kind of effect a spell caster could do .
hmm let me think about this somemore and i\'ll repost
I think im onto something concerning spells and alchemy perhaps there could be various ways of enchanting items
