Which of the following is a mixture? gold ore water table salt graphite

Much of the gold that is mined is actually from " gold ore " rather than actual gold specimens.

The ore is often brown, iron stained rock or massive white quartz, and usually contains only minute traces of gold. To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods.

So your answer is. "Gold Ore" is a mixture.

I hope this helps.
