Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Give the word/symbol equation. Carbon can be used to displace the copper. Put one spatula of copper oxide and one spatula of carbon into a test tube and heat until the copper oxide glows red, using test tube holders to hold it.

During copper smelting, arsenic is diluted and emitted in the gas and slag streams, necessitating special collection and handling procedures. Roasting, the first step in most copper smelters, is relatively inefficient as an arsenic removal process. Multiple-hearth roasters generally remove about 20 percent of the arsenic contained in the feed.
