Gold is one of the most inert metals and maintains high value due to scarcity. The world gold association estimates that all the gold that has been mined globally is so small that it can be loaded into a cube container 20 x 20 x 20 metres。
Gold is not abundant on the surface of the earth. Only 0. 004 grams of precious metals are estimated to be present in each ton of crustal material. So why is gold so rich in gold? It's always a geological mystery。
Canadian geoscientists say that gold, although not dynamic, dissolves in superheated acid groundwater (thermal fluids), and that geological activity allows these fluids to enter the cracks of the rock, where the gold will reconcrete and form deposits。
The other could be the adhesive solution. Solid kinami particles, scattered in hydrothermal and geothermal fluids, are mutually exclusive because of their charge. When the charge breaks down, the gold particles gather together to form condensation。
In this process, the geothermal fluids have a gold concentration of just a billion, but it's ludicrous. The adhesively formed gelatinous material, trapped in the cracks of the crust, creates a rich gold vein。
In addition, an international team of geochemists found that gold is often concentrated with arsenic, which explains the formation of most gold mines and why many gold miners remain at risk of arsenic poisoning。
Some gold is found in the form of gold blocks, and a considerable amount is combined with minerals。
Gold generally relates to minerals containing iron and arsenic, such as yellow ore and arsenic. These minerals act like sponges, which concentrate gold, millions more than gold found elsewhere in nature — for example, in hot springs。
Scientists have found that when the minerals contain arsenic, gold can be integrated directly into the mineral structure. When arsenic concentrations are low, gold does not enter the mineral structure, but simply forms a weak gold-sulphur key on the mineral surface。
Studies have shown that arsenic contributes to the concentration of gold. This arsenic-driven gold pump explains how these iron sulphides can capture and release gold on a large scale, thus controlling the formation and distribution of deposits。
