How Is Gold Formed and Where Does it Come From

May 18, 2015Gold isnt truly formedat least, not on Earth. Gold Comes From Outer Space. Gold, the shiny yellow metal prized for its beauty and malleability and used in many different industries, is actually created inside massive stars when they explode into a supernova. Of course, after a star supernovas and forms gold, the precious metal has to travel to Earth in some way.

Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types lode (primary) deposits and placer (secondary) deposits.

Gold extraction

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques
