The Extraction of Copper - Chemistry LibreTexts

Any metal in the impure anode which is below copper in the electrochemical series (reactivity series) does not go into solution as ions. It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold.

Extraction of Metals | Good Science

Metals exist in the earth’s crust either as native metals (elements) or minerals (compounds). The rocks and sand in which metal deposits are found are known as ores. Metal ores are mined from the earth’s crust, then metals are extracted from the ore. The form in which a metal exists in an ore depends on its stone reactivity.

Extraction of Metals - Methods of Extraction of …

Extraction of Metals: Ores and Minerals Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e., Gold, Silver, and Platinum etc. are present in their original metallic forms in nature.

Types of Extraction | S-cool, the revision website

Methods of extraction Many metals are found in the Earths crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more …
