What does gold in a rock look like?
Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron.
Much of the gold mined is actually from gold ore rather then actual Gold specimens.
The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold..
Is there an app that can identify rocks?
RockCheck application is identification key for rocks. It is a teaching aid that can be used to contribute to the teaching of geological contents within natural science subjects in the formal school system.
What types of metal are not magnetic?
Most other metals, for example aluminium, copper and gold, are NOT magnetic. Two metals that aren’t magnetic are gold and silver. They are often used for making jewellery, including crowns for instance.
What minerals can be found with a metal detector?
In addition, minerals such as fluorite, pyrite, and many others can be found as gangue minerals (i.e., a commercially non-valuable material that surrounds or is mixed with a desired mineral in an ore deposit) within gold ore. There is a wide variety of gold prospecting or nugget shooting metal detectors on the market.

Rocks are classified into three main types, igneous, sedimentary, and metamorphic, depending upon their mode of formation.
How do you identify an unknown metal?
You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. Assume that you have to identify an unknown metal. You can determine the mass of the metal on a scale.
