Gold is not typically extracted from the earth using Metallurgy. Instead, it is often found in its pure form as nuggets or grains in rivers and streams, making it easier to separate and collect through methods like panning or sluicing. This is why gold is often referred to as "native" gold.

What metals are not extracted from the earth using metallurgy?
Metals such as gold, silver, and platinum are often found in their pure form in nature and can be obtained without the need for extensive metallurgical processes. These metals are usually collected through mining or panning techniques rather than traditional metallurgy.
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
What is Pyro metallurgical process?
The word pyro metallurgy comes from two words=pyro+metallurgy where pyro means heat and metallurgy means extracting metals from their ores ,purifying and modifying the metals for use.So Pyro metallurgy is the process of extraction of metals from their ores and their purification with the application of heat.following is the list of pyro metallurgical processescalciningroastingdryingsmeltingrefiningExamples of elemnts extracted using pyro metallurgical processes are Fe, Cu, Zn, Chromium, Tin, Manganese.
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.
Why alkali and alkaline earth metals cannot be obtained by chemical reduction method?
Alkali and alkaline earth metals are highly reactive elements that readily form compounds with other elements. This high reactivity makes them difficult to isolate using chemical reduction methods as they will easily react with any available substance, such as water or oxygen, preventing pure elemental form from being obtained. Instead, alkali and alkaline earth metals are typically extracted through more complex methods, such as electrolysis or by using reactive metals like magnesium as reducing agents.

What metals are extracted using phytomining?
Metals such as nickel, copper, and cobalt are commonly extracted using phytomining. This process involves growing hyperaccumulating plants that can absorb high levels of metals from the soil through their roots. Once the plants are harvested, the metal-rich biomass is collected and processed to extract the valuable metals.
How are metals extractive?
well basically metal is extracted using carbon monoxide
What is the process of removing metals etc. from the Earth?
The process of removing metals from the Earth involves mining, which typically starts with exploration to identify mineral deposits. Once a deposit is found, the ore is extracted through mining techniques such as surface mining or underground mining. The extracted ore is then processed to separate and extract the desired metal using methods such as crushing, grinding, and chemical processes.
How is Potassium extracted from the earth or Atmosphere?
By using electrolysis from potash
What metals can be extracted from its ore by heat alone?
Metals like gold and silver can be extracted from their ores by heat alone. This is because these metals have relatively low melting points and can be separated from their ores through processes like smelting or cupellation where the ore is heated to high temperatures to extract the metal.
Fairly reactive metals found as ores?
Sodium, magnesium, and aluminum are examples of fairly reactive metals that are commonly found as ores in the Earth's crust. These metals can be extracted from their ores through processes such as electrolysis or chemical reactions.

What is the hydro metallurgy process of extracting copper ore?
Hydrometallurgy is a process that uses aqueous solutions to extract metals from ores. In the case of copper, the ore is typically crushed and then leached with sulfuric acid to dissolve the copper into solution. The copper is then extracted from the solution using techniques such as solvent extraction or electrowinning to obtain pure copper metal.
