How is copper extracted by phytomining?
Phytomining is a method of extracting metals from soil using plants that can accumulate metals in their tissues. In the case of copper, hyperaccumulator plants are grown on copper-rich soil. As the plants grow, they absorb copper through their roots and accumulate it in their shoots. The plants are then harvested and burned to release the copper, which is then extracted and purified.
How is copper processed in the mining industry?
Copper is processed in the mining industry through a series of steps. First, the ore containing copper is extracted from the ground. Then, the ore is crushed and ground into fine particles. Next, the copper is separated from the ore using a process called flotation. Finally, the copper is purified and refined to remove impurities and produce high-quality copper products.
Why does a potato acquire a greenish deposit at the anode during electrolysis of potato?
You do not mention what you are using as the anode and cathode, but i would assume that given the green colour you are using copper or brass perhaps as the anode, and it is breaking down into a copper carbonate(which is green). By applying electrical current to the circuit you are speeding up the conversion of copper to copper carbonate(or similar).
Why is zinc not extracted from zinc oxide through reduction using carbon monoxide?
Magnesium is a more reactive metal therefore for using any extraction method you would have to use electrolysis, which is expensive. Whereas for zinc it is extracted from its ore chemically by reduction using carbon. When an ore is reduced you are taking the oxygen out of the metal, this is because carbon can only take the oxygen away from metals which are less reactive than carbon its self. For example, zinc oxide is reduced in a blast furnace to make zinc.
Why can carbon be used to extract copper oxide?
Mg is a highly electro positive metal and hence has high affinity towards more electronegative element oxygen and thus ,oxide of Mg is very stable and can not be reduced by carbon (Carbon has less affinity than Magnesium towards oxygen). On the other hand , Zn being moderately strong electro positive metal , it has less affinity towards the more electronegative oxygen atom and its oxide is not very stable and hence can be reduced by Carbon easily (carbon has greater affinity than Zinc towards oxygen).
How copper can be extracted from copper(II)oxide using carbon?
Copper can be extracted from copper(II) oxide by heating a mixture of copper(II) oxide and carbon. The carbon, in the form of charcoal or coke, reduces the copper oxide to form copper metal and carbon dioxide gas. The reaction can be represented as: CuO + C -> Cu + CO2.
What metals can be extracted from their oxides using carbon?
Metals that are less reactive than carbon in the reactivity series, such as iron, lead, and copper, can be extracted from their oxides using carbon. The carbon reduces the metal oxide to the metal in a process known as reduction.
How can copper be extracted using scrap iron nothing it doesnt work that way?
Copper cannot be extracted using scrap iron because iron is less reactive than copper in the reactivity series. To extract copper from its ore, a process called electrolysis or smelting is usually used. During smelting, the copper ore is heated with carbon to remove oxygen and extract the copper metal.
Which metal is less reactive than sodium but cannot be extracted heating with carbon in a furnace?
Copper is less reactive than sodium but cannot be extracted by heating with carbon in a furnace due to its position in the reactivity series. Instead, copper is typically extracted using electrolysis or by reduction with more reactive metals such as iron.
How are metals that are less reactive than carbon extracted from their oxides?
Metals less reactive than carbon, such as copper and silver, are extracted by reduction using carbon as a reducing agent. The metal oxide is heated with carbon (in the form of coke) to form carbon monoxide, which then reduces the metal oxide to the pure metal and carbon dioxide.
What is the problem with using grade ore as a copper source?
The metal (copper) extracted may be generally brittle and break easily.
Which of the following metals in not extracted from the earth using metallurgy a Copper b Iron c Chromium d None of the above?
ALL OF THEM ARE EXTRACTED FROM EARTH IN THE FORM OF ORES. IRON IS EXTRACTED IN THE FORM OF:- HAEMATITE, Fe2O3 LIMONITE,2Fe2O3.3H2O MAGNETITE, Fe3O4 IRON PYRITE, FeS2 COPPER IS EXTRACTED IN THE FORM OF:- CHALCOPYRITE, CuFeS2 COPPER GLANCE, CuS CHALCOCITE, Cu2S MALACHITE, CuCO3.Cu(OH)2 CUPRITE, Cu2O CHROMIUM IS EXTRACTED IN THE FORM OF:- CHROMITE, FeCr2O4
How are metals extractive?
well basically metal is extracted using carbon monoxide

What compounds is named using an -ate suffix?
The suffix -ate indicates the presence of three oxygen atoms in the -ate molecule. e.g. copper carbonate is CuCO3- the Cu is the copper, the C is the carbon and the O3 is the -ate
Iron can be extracted from its ore using carbon. What type of reaction is this?
The extraction of iron from its ore using carbon is a reduction reaction, specifically a redox reaction. Carbon reduces the iron oxide in the ore by donating electrons to the iron, resulting in the formation of elemental iron and carbon dioxide.
What is reduction in metallurgy?
Reduction in metallurgy refers to the process by which a metal is extracted from its ore by removing the oxygen or other non-metallic elements present. This is typically done using heat and a reducing agent, such as carbon, to facilitate the chemical reaction that separates the metal from its compounds. Reduction is a crucial step in the production of metals like iron, copper, and aluminum.
