Provided are a gold mining and processing method. The method comprises steps of: A. After gold ore are mined, grinding the gold ore to obtain a gold mine raw material; B. Processing a gold ore material of weight m at a temperature of 150-200 °C and a total pressure of 2500-3500 kPa to produce an oxidized solid mineral; C. Mixing 3%-10% of the oxidized solid mineral into another gold ore raw material of weight m and processing again at a temperature of 150-200 °C and a total pressure of 2500-3500 kPa to produce an oxidized solid mineral, and repeating the step C; D. Transferring the remaining oxidized solid mineral of steps B and C to a vessel having an oxygen pressure of 3000-6000 kPa for cyanation for 35-60 minutes to recover Au.
