this is because metals like platinum,gold and silver are noble metals,they do not easily mix with impurities such as silica,potassium etc. And even if they do mix it can be easily separated by adding a acid to it.Hence, these metals are present in free state.

Answer 2

you will wonder why metals like gold silver and  platinum are placed the lowest

this is bcz they are the least reactive

so they dont like to react with other metals thus they remain in free state in nature
