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.

Extracting copper from other ores. 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.

In this lab you will extract copper from malachite, a copper ore. Ore - a material used as a source of metal. Introduction: Most metals are found in the earth's crust combined with other elements. These materials are called ores. A common copper ore is malachite CuCo3. In this lab you will extract the copper (Cu) from the malachite.

1. You will need a small piece of malachite (about 1 cubic inch), a greenish mineral whose formula can be written as Cu 2 CO 3 (OH) 2 or CuCO 3-Cu(OH) 2. This can be purchased from science supply companies. As with most copper ores, the malachite does not contain pure copper (native copper), and will contain other minerals besides the malachite.

Copper can be extracted from its ore by: 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 method. Ores near the surface can be quarried after removal of the surface layers.

Copper Mining & Extraction Process Flow Chart. This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).

Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2

Sulfamic acid (SA), which possesses a zwitterionic structure, was applied as a leaching reagent for the first time for extracting copper from copper oxide ore. The effects of reaction time, temperature, particle size, reagent concentration, and stirring speed on this leaching were studied. The dissolution kinetics of malachite was illustrated with a three …

Malachite is a fairly hard rock, but copper oxide is very soft and crumbly. This is because it gets broken up as the carbon dioxide comes out of it. As the rocks crumbled, more of the copper oxide would have been moved into the middle of the fire where it got hotter. Add the copper oxide to the beaker and add the carbon.

Dec 15, 2020. #2. Hi You need to reduce the malachite first to copper oxide on a fierce flame. It will go black, then you add the carbon and heat for about 20 -30 mins. I have never had solid copper metal but you should bet semi solid copper powder. It helps if you can use small chunks of malachite too as it will reduce quicker and easier.
