Can you find gold in coal?
Gold occurs as palaeoplacers and in hydrothermal deposits. Gold occurrences reflect rapid erosion of the mineralized orogeny and young provenance of sediment in the coal basins. The disposition of the Variscan Orogen through equatorial latitudes made coal an exceptional reservoir for gold.
Which is considered as the highest rank of coal?
What is the hardest known mineral?
Which rock contains valuable minerals?
How do rocks and minerals compare?
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids. Some rocks are predominantly composed of just one mineral.
