The invention provides a production method of an ore brine crystal salt. In the method, ore brine is used as raw brine, wind and sunlight are used as energy sources, and a shoal pool is used as a crystallization pool. The production method is characterized by comprising the following steps: after exploiting the ore brine, firstly passing the exploited ore brine through a pipeline and then weighing with a pump station, respectively storing the weighed ore brine crystallization salt in a brine hoarding table, pouring to a crystallization pool from the brine hoarding table, and evaporating and crystallizing through the wind and sunlight in the crystallization pool; and controlling the concentration and depth of the brine, properly adding or replacing novel brine, mastering the depth and market demand of the crystal salt, discharging the brine and recovering the salt timely, and recycling the old brine. According to the invention, energy consumption is low, 0.18 ton of coal and 50-60kw.h of electricity are consumed for producing every ton of ore salt, and the electricity consumption of every ton of salt is about 5kw.h in the invention; large land area is saved and accounts for 1 / 20 of that of sea salt; the method is environmentally-friendly, and zero emission is basically achieved; and the produced ore brine crystal salt has high quality, meets a GB / T5 462-2003 prior industrial salt standard, has extremely less impurity ions and large crystalline particles, and is especially suitable for a chlor-alkali industry.
