For lead and zinc, there is the Teck-Cominco smelter in Trail, BC, Canada. For copper, there is the Glencore smelter in Quebec, Canada. These are all I know of in North America. They won't be interested unless you have at least several hundred tonnes of concentrate. Minimum grades need to be 20-30%, and they are very specific with what kind of impurites are allowed and at what maximum concentrations. For example there are maximum allowable levels of things like arsenic in the concentrate, if your concentrate exceeds these levels, there will be a penalty deducted from the final payout. You need to get a good representative sample, and have it assayed, probably before you even talk to them.

Teck-Cominco smelter in Trail, BC, Canada also processes leaded glass from CRT's

Glencore smelter in Quebec, Canada also process electronic circuit boards. You would need multiple 40 ton loads.
