Extracting copper from copper(II) carbonate
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. If possible, show the class a genuine sample of malachite ore and artefacts, such as paperweights or polished 'eggs' made from malachite, noting ...
Extracting metals with charcoal
Experiment 2: copper(II) oxide. Transfer one spatula measure of copper(II) oxide to a hard glass test tube. Carefully add one spatula of charcoal powder on top of the copper oxide without any mixing. Strongly heat these two layers for five minutes in a Bunsen flame. Allow to cool and then look closely at where the powders meet in the test tube.
The extraction of copper
The extraction of copper: a microscale version Copper can be extracted from copper oxide using hydrogen. The risk of an explosion makes this experiment quite hazardous on a large scale, but when approached with care it can be done safely on a microscale level. Equipment • 1 comboplate® • 2 cm3 syringe • 1 x lid number 1
The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

inorganic chemistry
In a crucible, we added copper carbonate and the total weight of both is 37.04g. After, we heated the crucible with the copper carbonate. It was easy to judge when the reaction had taken place as the colour of the substance had changed from the light green of copper carbonate to the black of copper oxide.After we observed this, we weighed the ...

Metal Extraction (solutions, examples, activities, experiment, videos)
1. Copper(II) oxide is a black, powdery solid. 2. The gas formed is carbon dioxide. 3. The solid remaining after heating is a pink solid. 4. The solid formed is copper. 5. copper(II) oxide + carbon → copper + carbon dioxide 2CuO + C → 2Cu + CO 2 6. Carbon is more reactive than copper because carbon displaced copper to form carbon dioxide. 7.

Microscale extraction of copper
In this experiment, students heat copper(II) oxide in the presence of hydrogen gas to extract copper. The copper(II) oxide reacts with hydrogen and is reduced, producing copper and water. This can be used to show the relative positions of copper and hydrogen in the reactivity series, and can also be used for percentage yield-type calculations.

PDF 33. Extracting metal with charcoal
This extraction experiment consists of two competition reactions. A metal oxide is reacted with charcoal. If the charcoal (carbon) is more reactive it will remove the oxygen from the metal oxide and leave a trace of metal in the reaction vessel. Start with an oxide of lead, then observe what happens to an oxide of copper. What to do Lead oxide 1.
copper extraction and purification
Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper (II) sulphate solution. Concentration of the copper (II) sulphate solution by solvent extraction.
The extraction of copper: a microscale version
The reactants are copper oxide and hydrogen. copper oxide + hydrogen → copper + water CuO(s) + H2(g) → Cu (s) + H2O(l) Oxygen is lost from the copper so this is a reduction reaction. (Note: The hydrogen is also oxidised - this is a redox reaction.) Hydrogen is more reactive - it takes the oxygen from the copper. a.

The first experiment uses lead(II) oxide; the second modifies the technique slightly and uses copper(II) oxide. Lesson organisation The solids may be dispensed in plastic weighing dishes. It is best not to issue all three solids at the same time because students may confuse the charcoal and the copper oxide. The experiment should take about 30 ...

Finding the formula of copper(II) oxide
In this experiment, students heat copper(II) oxide in a glass tube while passing methane over it, reducing the copper(II) oxide to copper. If they weigh the reactants and products carefully, students can then deduce the formula of the copper oxide. This can also be used simply as an example of reduction.
