Extracting metals (boardworks) [PPT Powerpoint]

Apr 22, 2015· In industry, an ore is a rock that contains enough metal to make mining and extraction economical. However, the value of ores changes over time due to society and technology. For example, rocks containing only 5% copper would have been considered unprofitable in the 19th century. Today, most copper comes from ores containing 0.4 to 1% copper.

Obtaining and Using Metals Edexcel T4 revisechemistry.uk

The least reactive metals are found in their native state in the Earth's crust.This means they are found as uncombined elements. Any metal more reactive than hydrogen, but less reactive than carbon, can be extracted by adding carbon to displace the metal from its oxide (or other compounds).This is known as reduction.. The most reactive metals have to be extracted using electrolysis, as carbon

Reduction of Metals (Extraction from Ore)  ALevel Chemistry

Reduction of Metals (Extraction from Ore) ALevel Chemistry

There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon

Extracting copper from copper(II) carbonate  Experiment

Extracting copper from copper(II) carbonate Experiment

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.
