Absolutely Pure Gold with High Fineness 1000‰ [PDF]
Springer Proceedings in Earth and Environmental Sciences, 2019 It is identified for the first time that, during process of complicated deformation in eolian conditions - mechanical transformation of flaky gold into toroidal form and then into globular-hollow form, gold is cleaned up to absolutely pure metal with fineness 1000‰. Note that, fineness of this eolian gold is higher than fineness of the reference object,
