Patent number: 11427885Abstract: An apparatus for separating and recovering the components of an alloy, particularly a noble alloy, including a high vacuum chamber housing at least one crucible for the alloy to be separated; at least one heating element arranged, during use, around the crucible; at least one condensation device, which faces, during use, an upper mouth of the crucible. The particularity of the present invention resides in that the condensation device includes at least one cold element and at least one deflector that is adapted to divert the flow of the aeriform substances derived from the melting and evaporation of the alloy toward the cold element. The invention also relates to a process for separating and recovering the components of an alloy, particularly a noble alloy.Type: GrantFiled: December 19, 2019Date of Patent: August 30, 2022Assignee: IKOI S.P.A.Inventors: Giovanni Faoro, Aleksandr Khlebnikov, Denis Borovkov, Sergey Medvedev, Sergey Grokhovsky

Patent number: 11154924Abstract: A process for producing metal ingots includes the steps of: a) filling at least one ingot mould at a filling temperature with at least one metal charge in the solid state, which has a melting temperature higher than ambient temperature, b) melting the metal charge by heating the ingot mould to a heating temperature higher than or equal to the melting temperature of the metal charge, c) solidifying the molten metal charge into an ingot by cooling the ingot mould to a cooling temperature lower than the melting temperature of the metal charge and higher than the ambient temperature, d) extracting the ingot from the ingot mould at an extraction temperature, and e) repeating steps a) to d). At steady state, both the filling temperature and the extraction temperature are lower than or equal to the cooling temperature and higher than the ambient temperature.Type: GrantFiled: January 8, 2019Date of Patent: October 26, 2021Assignee: IKOI S.P.A.Inventor: Giovanni Faoro
