Gold has been recovered from some pretty lean ores, being profitably extracted from ores yielding less than two hundredths of an ounce in a ton of rock. However, this is the result of work done on a gigantic scale like the open pits of the Carlin district in Nevada. For individual prospectors and other small operators, gold-bearing quartz ores

Gold is usually associated with Pyrite and other sulfides, and sometimes may not be noticed because of the association with these resembling minerals. In certain localities, minerals that contain these sulfides are heated high enough for the sulfides to dissolve, enabling the Gold to remain intact on the matrix

Limonite deposits are usually too small and too impure for use in modern metallurgy. Names such as "brown iron," "brown hematite," "bog iron," and "brown ocher" have been used by miners to relate limonite with its potential uses. Their use has declined significantly, and the name "limonite" is now used for these various materials

The problem is that gold occurs in many types of deposits, and what indicators work great for one type of deposit don’t always work well for another. As an example, in some places the presence of vein quartz on the ground is a valuable indicator, yet I have been in places where there is so much vein quartz everywhere that is worthless as an

Mar 17, 2017 · The ores, which have been met with in various parts of the world, consisting mainly of limonite or hydrated oxide of iron, and in most cases believed to be the result of decomposition of pyritic ores by atmospheric agencies, are also extremely refractory, causing the mercury to sicken rapidly, and yielding only about the same percentage of gold as can be obtained from unoxidised pyrites

May 22, 2018 · Limonite is mainly derived from weathering of Fe sulfide, iron-bearing carbonate, or silicate minerals. The weathering of Fe sulfide or carbonate minerals to yield limonite from the Tongling mineralization cluster has been studied extensively. Knowledge of the mineralogical and geochemical characteristics of the limonite from weathering of Fe-bearing silicate minerals is still incomplete, …

Jul 23, 2018 · Gold mining continued to escalate and from 1840 to 1849, Virginia produced an average of 3,000 ounces of gold annually. But all good things must end and when the California Gold Rush began in 1849, most miners moved west in search of greater profits. The California Gold Rush didn’t just impact mining in Virginia, but along the entire East Coast

Gold Prospectors like to generalize gold deposits into two groups - lode gold (gold which is found in place in outcrop) and placer gold (detrital gold eroded from a nearby lode and deposited in a stream). Both deposits are important, but for the gold prospector, placer gold deposits are most important because many can be worked with smaller resources and less cost that most lode gold deposits
