Copper Metal from Malachite circa 4000 B.C.E. Journal of Chemical Education, Vol. 81 No. 12, pgs. 1777-1779. Retrieved from JCE.DivCHED.org. This lab extracts the copper from an ore with the mineral malachite, basically copper carbonate hydroxide Cu 2CO 3(OH) 2, as people may have done it, more primitively, at the beginning of the copper

Copper Metal from Malachite circa 4000 B.C.E. Journal of

Around 6000 years ago the procedure involved heating copper ore in the presence of charcoal; we have created a laboratory experiment inspired by this idea. The experiment starts with a naturally occurring ore, malachite, essentially pure Cu2CO3(OH)2, which is readily available at modest cost in bead form from jewelry stores.

Dec 01, 2004· The experiment starts with a naturally occurring ore, malachite, essentially pure Cu2CO3(OH)2, which is readily available at modest cost in bead form from jewelry stores. Using only a Bunsen burner, a porcelain crucible, and a charcoal briquette, the experiment demonstrates two steps in the ancient processing of copper ore: roasting and reduction.

Recovery of Copper from Malachite

Pre-Lab. Introduction: You will acquire a metal with the cation Cu+2 from a solution in this experiment. The mineral malachite contains copper (II) ions as both copper (II) carbonate and copper (II) hydroxide. You will extract the copper ions from the malachite by adding sulfuric acid.

ERIC EJ717285 Copper Metal from Malachite Circa 4000 B

Dec 01, 2004· The feasibility of the laboratory production of copper metal from a readily available, naturally occurring mineral malachite utilizing techniques that are consistent with the time period of around 4000 B.C.E. is presented. The starting materials are inexpensive and convenient and the procedure involves no hazardous reagents and produces no hazardous wastes, thus representing a
