2001-7-31  Impure gold, as it commonly occurs in deposits, hasa density of 16 to 18, whereas the associated wasterock (gangue) has a density of about 2.5. The differ-ence in density enables gold to be concentrated bygravity and permits the separation of gold from clay, silt, sand, and gravel by various agitating andcollecting devices such as the gold pan, rocker, and sluicebox.

How to Identify a Gold Bearing Area Sciencing

2017-4-25  Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better chance of finding desired amounts of gold.
