The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The metals of antiquity generally have low melting points, with iron being the exception. Mercury melts at −38.829 °C (−37.89 °F) [21] (being liquid at room temperature). Tin melts at 231 °C (449 °F) [21] Lead melts at 327 °C (621 °F) [21] Silver at 961 °C (1763 °F) [21] Gold at 1064 °C (1947 °F) [21] Copper at 1084 °C (1984 °F ...

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
But the differences happen away from the minimum composition. Unlike silver with fineness other than 719 (which melts partly at exactly 780 °C through a wide fineness range), gold with fineness other than 800 will reach solidus and start partial melting at a temperature different from and higher than 910 °C, depending on the alloy fineness.
Engineers heat the gold-plated steel to temperatures exceeding 1,000 degrees Fahrenheit — hot enough to melt the gold but not the steel. The gold mine, Yanacocha, is a massive operation, sprawling across hundreds of square miles at elevations as high as 13,000 feet.
