This KS3 education resource looks at copper mining, extraction and pyroprocessing of sulfide ores.
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods.

Jan 26, 2011 Thermophilic bacteria are actively prevalent in hot water springs. Their potential to grow and sustain at higher temperatures makes them
than carbon, it can be extracted from its compounds by heating with carbon. Copper is an example of this. Copper mostly occurs as sulfide ores, which are
Roasting in Air: Used in extractingcopper from copper (I) sulphide (copper pyrites). The copper is extracted by roasting the ore in air. Recycling metals Metals are
Copper can be extracted from its ore by heating it with carbon. Impure copper is purified by electrolysis in which the anode is impure copper, the cathode is pure
How to extract copper from ores? How do we purify impure copper by electrolysis carbon reduction of copper oxides, sulfides carbonates are described.
COPPER. This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the
For example, high grade copper ores are becoming harder to find and mine. There are some alternative methods to extract metals. from low grade copper ores
underground, sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. open pit, 90% of ore is mined by this
Although this requires more ore to be extracted and processed, this process is less The first steps of copper processing are the same for both ores: mining and
Analysis of Copper Ore for Cu Content. Introduction: Copper, in various forms, has been mined from the Earth ever since mankind started using metal tools.
Copper is found in natural ore deposits around the world. The following gives an overview of how copper is extracted from its ore and converted into pure
usually extracted from ores using a combination of heating and reduction with carbon in the form Copper can be extracted from its ores by reduction. One of
Metals are found as ores buried in the Earth's crust. So how do we get to the final metal? There are three main stages. mining; extraction; purification. Let's look
