I think the word you seek is Panning, not Planning. Gold, when found as a fairly pure metal, can be separated from rock/sand by panning or a sluice box due to the much greater weight of gold. However, iron is rarely found as a pure metal, but as an ore that must be refined to get iron. The iron is chemically combined with something else, such as oxygen.
No. Since gold in an element it cannot decompose.
Gold. Gold is an element, so it cannot be created from other elements.
You would get, of course, either lead or mercury
You cannot reduce gold. It is an element on the periodic table. But you can melt, crush, and other things to gold.
Uhh... no, Gold is A metal on the element chart, it cannot be a gas

gold is an element because it cannot be broken down any further if it was it wouldn't be here http://www.webelements.com/

With the exception of very small scale transformations during atomic reactions, you cannot MAKE any element- and gold is an element.

This is a chemical element as gold or platinum.
If it cannot be broken down and has the same properties, it is an element.
One reason is that gold is considerably denser than iron and therefore sinks more consistently to the bottom of a shaken pan. Another reason is that iron rarely occurs in nature in elemental form, while gold relatively often does occur naturally in elemental form.
A substance that cannot be broken down is a pure substance
Gold is an element. It cannot be broken down into any simpler substance, and can be found in the periodic table with the symbol of Au. number 79.
