A ceramic cruicible with this kind of spring coiled wire wound around it would take you to 1200 deg this can be done if you need to control the temperature to an accuracy of 2 - 3 degrees using a temperature controller with a chromel / Alumel thermocouple probe. You will have to use a digital PID conrtoller connected to a 63 Amps contactor to switch on and off to maintain the required temperature.
If you need to reach a temp of 1350 deg C then use an alloy of Iron-chromium-aluminium wire of about 2mm dia which has 25% chromium and 5% Aluminium and bal Iron and some rare earths.
Well if all this sounds a little complicated then use a blowtorch by placing the metals to be melted in a ceramic cruicible which usually withstands temp of more than 2000 deg C.
Get to the link below as to what to do to the impurities once you melt to the required temperature. GOLD MELTS AT AROUND 1100-1150 Deg. C
