The above flowsheet shows a basic copper mine process, from mine to metal. There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper. The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction (SX). The SX process concentrates and purifies the copper leach solution so the copper can be recovered at a high electrical current efficiency by the electrowinning cells. It does this by adding a chemical reagent to the SX tanks which selectively binds with and extracts the copper, is easily separated from the copper (stripped), recovering as much of the reagent as possible for re-use. The concentrated copper solution is dissolved in sulfuric acid and sent to the electrolytic cells for recovery as copper plates (cathodes). From the copper cathodes, it is manufactured into wire, appliances, etc. that are used in every day life. Below are some photos of the process equipment at an Arizona Copper Mine.
by heating limestone with carbon and then degrading it
it is created by people melting it in heat and molding it
They came from mines and recycled copper.
the chemical formula of copper carbide is CuC2.
copper and iron (II) chloride
copper hydroxide

It can't be grown or produced synthetically.

Depends on the acids you're mixing the copper with!
They are elements. However, pure iron, gold and copper are produced from naturally occuring ores. In that respect, they are produced.
Pennies produced in 2004 were made from copper-plated zinc. Pennies with 95% copper metal have not been produced since 1982.
copper (thiocyanate)2 and potassium nitrate
Copper oxide and hydrochloric acid will produce copper chloride.
It can't be grown or produced synthetically.
