Small lines of gold can be removed from the cracks in Katinkulta’s crystal structure by new methods. They may even be worth it.
“Worthless cat gold… ”Impact singers Checkmate and Teppo at the latest, the Finns assured in their chorus that the shimmering gold of cat gold is not real gold.
Many of us were deceived by cat gold as a child. It sparkles enticingly, but it’s just mineral pyrite or pyrite.
The mineral gets its name from sulfur, but the value of it and the other cat gold ingredient is nowhere near gold.
Katinkulta has also cheated many mine workers over the years. Sulfur pyramid is commonly found in, for example, quartz lines and various types of stone.
Now it’s time to slightly change perceptions of cat gold. That’s when you can actually contain very very small amounts of real gold.
Katin gold pyrite contains ferrous sulphate with iron and sulfur. Pyrite and gold are formed under similar conditions. Therefore, pyrite can first show that real gold is near.
I tried crystals sometimes contain tiny nanoparticles that are genuine gold. It sticks to the crystals as the cat gold crystallizes.
The metallic pyrite is a crystal. It therefore means that its atoms are arranged in a regular and predictable form.
However, no crystal is perfect, says the geologist Denis Fougerouse. He is studying the economic value of minerals at Curtin University in Australia.
Fougerouse found with his groups that gold can hide in pyrite in those small places where the crystalline structure of pyrite is for some reason irregular and broken.
“The more the crystal is deformed, the more real gold there is in Katinkulla,” Fougerouse says the online magazine LiveScience.
Irregular structures are a hundred thousand times thinner than the width of human hair. They contain real gold with a special technique called tomography of atomic sensors.
Until now, in techniques, electrical pulses have peeled atoms out of a sample. The surface is inspected one layer at a time. The method has destroyed thin, wire-like gold samples.
However, Fougerouse and his group found ways to extract small gold traces from the pyrite without destroying them.
“Gold is usually extracted by pressure. It consumes a lot of energy, ”Fougerouse says. Therefore, he explored more environmentally friendly gold extraction.
Fougerouse and his team investigated the value of gold lurking in Katinkulla when calculating the cost of its exploration.
Extraction of gold could be worthwhile at the mine with new techniques, especially when gold is extracted from a relatively environmentally friendly means.
“There are fewer and fewer new gold deposits in the world. At the same time, the quality of gold-containing ore is deteriorating. However, the value of precious metals is rising, ”Fougerouse ponders the profitability of Katinkulta’s gold on the website phys.org.
Slight the gold is extracted from the boiling gold by selective dissolution. In it, the liquid dissolves the precious metal from the stone so that the pyrite containing gold is not damaged.
The researchers found that the same small cavities that Katinkulta’s gold contains are at the same time channels that help gold get out of the rest of the mineral.
Katink gold told the scientific journal Geology.
