Gold ore can be mined with an iron or diamond pickaxe (just hold the pickaxe and then hold down the mouse button to start mining). Gold ore is then smelted into individual gold ingots, exactly similar to the process listed for iron ingots. However, when it comes to gold ingots, these items can be broken down even further into gold nuggets.
