Equipment for oxidizing, processing and smelting refractory gold ore by supercritical water

The utility model relates to equipment for oxidizing, processing and smelting refractory gold ore by supercritical water. The equipment comprises a feeding barrel, a metering plunger pump, a heat exchanger, a vapor-liquid mixer, a metering gas booster, a gas storage tank, an oxidant gas filter, a primary heating reactor, a secondary reactor, a primary separator, a secondary separator, a thermocouple thermometer, a controllable pressure gauge and a high-frequency electric heating sleeve. In the equipment, solid and water mixed liquid of refractory gold ore powder and oxygen or air after being pressurized or hydrogen peroxide are in oxidizing reaction under a supercritical water oxidization state. The equipment is provided two stages of reactors, so that organic matters in the solid and water mixed liquid is oxidized more thoroughly. After the equipment processes and smelts the refractory gold ore, As2O3 and SO2 pollution is omitted, the problem of environmental pollution is resolved, and recovery of gold ore i
