Min. 2 kg mineral.
In sulfide veins and scattered throughout igneous rock, chalcopyrite is found in many locations throughout the world.
170 kilograms equals 170 kilograms.
3.5 kilograms
1450g = 1.45 kilograms.
48 kilograms. you times the number by .10 to get the 10%
In chalcopyrite, the typical copper content is around 34.5%. To obtain 420 g of pure copper, you would need to mine around 1217 g of chalcopyrite. This is calculated by dividing 420 g by 0.345 (the percentage of copper in chalcopyrite).
In sulfide veins and scattered throughout igneous rock, chalcopyrite is found in many locations throughout the world.
It is not possible to answer this question with a precise number, because diamonds are being mined daily, lost daily, and formed daily.
Each pound is 0.4535924 kilograms (see the reference). Thus we multiply 25*0.4535924 to obtain the answer of 11.33981 kilograms. In the future, enter "pounds to kilograms" in your favorite search engine, then multiply by 25 ;-)
Chalcopyrite is commonly found in hydrothermal veins associated with copper deposits worldwide. It is also found in some sedimentary rocks and metamorphic environments. Major sources of chalcopyrite include regions like Chile, Peru, the United States, and Australia.
1 kilogram = 1000 grams. Basically, move the decimal backwards three times and obtain 0.275kg.
