How are the very reactive metals high up in the reactivity series extracted from their ores?
Very reactive metals high up in the reactivity series, like sodium and potassium, are extracted from their ores through electrolysis. The metal ions in the ore are reduced at the cathode, while oxidation occurs at the anode. This process is energy-intensive due to the high reactivity of these metals.
Which metals are extracted from their ores by thermal decomposition?
Metals such as zinc, mercury, cadmium, and tin are extracted from their ores through thermal decomposition. The ores are heated to high temperatures, causing them to break down and release the metal in pure form.
What metals are extracted by froth flotation technique?
Froth flotation is commonly used to extract sulfide ores of copper, lead, zinc, and nickel. These metals are typically extracted from their ores by creating a froth that selectively separates them from the gangue materials.
How many metals were obtained from ores?
The number of metals obtained from ores varies widely, as there are over 80 different metals that can be extracted from various types of ores. Commonly extracted metals include aluminum, copper, iron, lead, nickel, gold, silver, and zinc, among others. The specific number of metals obtained also depends on advancements in extraction technology and the economic viability of mining certain ores. Overall, while many metals are sourced from ores, the focus is typically on a select few that are most widely used in industry and manufacturing.
Why is the reactivity series important when extracting metals from ores?
By knowing the reactivity series of elements, we can tell which elements will displace each other. So to extract a metal from an ore, you need to use an element higher up in the reactivity series, so that the metal will be replaced by the other element, and you are left with a more pure form of the metal.

Where are metals extracted from?
Metals are extracted from various ores that are mined from underground.
What are the important ores?
Their importance is that these ores can be extracted into metals .

Do metals in the earths atmosphere must be mined and separated from their ores?
Metals found in the Earth's crust must typically be mined and extracted from their ores in order to be utilized. Through mining processes, the ores are extracted and then undergo various separation techniques to isolate the desired metal for industrial and commercial applications.
Are ores and rocks minerals or metals?
Ores are mineral deposits that contain metals in concentrated form. Rocks can also contain minerals, but not all rocks are considered to be minerals. Metals are elements that are typically extracted from ores through mining and processing.

How are minerals extracted from their ores?
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
What is the relationship between the reactivity of a metal and the date it was first extracted?
The less reactive a metal is, the more likely it is to be found native in the Earth, or the easier it is to extract. By and large, the reactive metals, which are hard to extract, were discovered later.
Why is the reactivity series important when extracting metals from ores?
By knowing the reactivity series of elements, we can tell which elements will displace each other. So to extract a metal from an ore, you need to use an element higher up in the reactivity series, so that the metal will be replaced by the other element, and you are left with a more pure form of the metal.
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.
