The invention relates to a nitronatrite comprehensive utilization method which simplifies the mining method, improves the mining efficiency, and reduces the mining cost. According to the method, nitronatrite single production sodium nitrate brine is extended to production of sodium nitrate brine and potassium nitrate brine, iron powder, and gold concentrate sand. The main steps of the method are as follows: (1) a heading machine is used for mining nitronatrite; (2) the nitronatrite is broken, and enters into a mill for further milling into powder, during milling, water is added into the mill, milled matters (a mixture of mineral powder and water) passes through a magnetic separation machine for separation of the iron powder; (3) the mixture is conveyed by a pump into a centrifuge, the mixture liquid separated by the centrifuge enters into a high frequency linear dehydration sieve, heavy mass matters enter into a table concentrator for further enrichment of the gold concentrate sand; (4) water (brine) separated by the high frequency linear dehydration sieve is pumped into a brine storage pool, and the water (brine) is concentrated to 120 grams/liter by circulation concentration; and (5) tailings enter into a classifier for secondary washing, the tailings separated by the classifier is conveyed by a conveyor belt to a tailing pile, and the used circulating water is pumped into a water reservoir for standby use. The nitronatrite comprehensive utilization method has high ore utilization rate, low comprehensive cost, and remarkable economical benefit.
