Jul 10, 2021  Carbon may also be left in the metal as an impurity. Sometimes this can be removed afterwards (for example, in the extraction of iron); sometimes it can't (for example in producing titanium), and a different method would have to be used in cases like this. Other more reactive metals can be used to reduce the ore.

Extraction Of Metals Definition, Factors Occurence

Dec 06, 2019  In initial years, iron metal was optimized to be extracted by different methods. The branch of metallurgy dealing with extraction of metals from salts is called “extractive metallurgy”. This is done by processing minerals containing metals. Factors for deciding method of extraction: Presence of metal to be extracted in reactivity series.

Extraction of Metals CIE IGCSE Chemistry Revision Notes

The extraction of metals is a reduction process. Unreactive metals do not have to be extracted as they are often found as the uncombined element as they do not easily react with other substances. Extraction of metal and the reactivity series. The position of the metal on the reactivity series influences the method of extraction.

Extraction of Metals Good Science

These metals are known as native metals. The chemical reactivity of metals also determines their method of extraction. Native metals undergo physical separation processes, such as froth flotation. Froth flotation uses detergents to create floating bubbles that adhere to metal particles, while other materials settle out and are removed separately.
