How to Identify a Gold Bearing Area | Sciencing

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.

Mercury-Free Gold mining Technologies - CBD

Gold extraction using mercury is comprised of the following four stages: 1) amalgamation, 2) separation of amalgamation, 3) removal of excess mercury, and 4) burning of the remaining amalgam to produce a gold sponge. Mercury can be released into the environment at each stage, which makes the promotion of mercury-free alternatives imperative.

Free gold can be rapidly recovered in high amounts using gravity concentration methods. Traditionally, simply exploiting the high specific gravity of free gold for recovery required little energy and was profit-generating. Today, however, more milling energy is consumed due to the change in mineralogy of gold

Gold Milling Process -Primitive and Basic

Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time, 1890, the Author said "There is, of course, nothing for us to learn from this imperfect and rudimentary gold-extraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt

Gold Statistics and Information - USGS

Gold has been treasured since ancient times for its beauty and permanence. Most of the gold that is fabricated today goes into the manufacture of jewelry. However, because of its superior electrical conductivity and resistance to corrosion and other desirable combinations of physical and chemical properties, gold also emerged in the late 20th century as an essential
