How do you conserve copper?
Copper (and other metals) are recycled by scrap metal companies or industrial processors. The metal recyclers buy scrap from individuals or companies. Industrial users take "drops" or "left overs" from production and sell them back to metal suppliers for reuse. For instance, if a company making tubing has bits and pieces of material that were pulled from the beginning or end of a production line, they'll gather them up, stick them in a bin, and vend it to a metal recycling company. Large companies doing demolition often include language in the contract that allows them to do some salvage during the process of removing a structure. Copper wiring and plumbing will be pulled, steel support structures might be recovered, and other materials can be removed for re-use as it is cost-effective to do. Metals end up at the recyclers' yards, and they separate and process the various things they buy. Their end products will be sold to different companies that smelt these metals for forming and eventual reuse. Interestingly, copper that is recycled is generally not used to make wire for use as an electrical conductor. It's too expensive to get the copper pure enough to use in wire. Instead, it's used heavily in copper tubing manufacture and in other applications. In any case, copper is a sought after metal for recycling.
