Selective Flotation
Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner’s mistake made by non-operating types. You do not need to pump anything in the […]
Reduction Potential Gold
The oxidation-reduction (dissolution and precipitation) of gold from Au –> Au+ +e- is driven by this equation. Without using a gold periodic table or a oxidation potential chart, you can simply review the chemistry here: Figure 1 is Au–H2O system: No stability region for gold ions between lines; can’t dissolve Au in aqueous solutions (for now) Figure […]
Gold Oxidation States
With regards to the aqueous chemistry of gold and the various states of gold oxidation ( 5, 3, 2, 1, −1 (an amphoteric oxide)), we must look at the electronic presentation typical of transition metal elements (Copper, Silver, Gold) AKA Group 11 element from the periodic table, because they allow for the extraction of multi electrons. As shown in the […]
Can you turn Copper into Gold
See how you can turn copper into gold:
Gold Dissolution
Essentially state and corrosion resistant, gold dissolution is not easily obtained by just any acid. Use an oxidant like manganese dioxide, nitric acid, oxygen, ferric ions or cupric ions and you will dissolve gold. The formation of Aqua Regia by nitric and hydrochloric acids will break down gold and make it go into solution. In the presence […]
World’s Main Gold/Auriferous Mineral Deposits
Era Precambrian (3000-570)* Paleozoic (570-225)* Mesozoic (225-65)* Cenozoic (65-0)* Age of host rocks Gold-quartz deposits mainly in Archean rocks (>2500 m.y.); extensive deposits in Proterozoic quartz-pebble conglomerates; some large gold-quartz and varied stockwork deposits in Proterozoic rocks Mainly Paleozoic; some deposits in Precambrian or both Paleozoic and Precambrian rocks Mainly Mesozoic but also Paleozoic and […]

Where are Vein Mineral Deposits Found
Where or how do vein mineral (gold, copper, nickel, silver, etc etc) are found is be exploring and sampling. As shown here, if you find some showings with increasing concentration, you are getting closer to the vein and maybe the Bonanza!
