Question

collect information about extraction of metals of low reactivity silver,platinum,and gold and prepare a report

Answer 1

well you can have one online other wise low reactivity metals are often found free in nature so this is't kinda great agenda to extract them due to their low reactivity

Answer 2

Answer:

Extraction of metals at the bottom of the activity series (Ag, Hg etc)

Metals at the bottom of the activity series are often found in free state. Their reactivity with other atoms is very low. The oxides of these metals can be reduced to metals by heat alone and sometimes by displacement from their aqueous solutions.

Explanation:

For example When cinnabar (HgS) which is an ore of mercury, heated in air, it is first converted into (HgO) then reduced to mercury on further heating.
