The invention discloses a production process for refining secondary brine by replacing sun-dried sea salt with well and rock salt. The production process for refining secondary brine with sun-dried sea salt uses the sea salt and the well and rock salt as raw material salts, wherein the raw material salts contain not less than 25% by mass of sea salt; the content of the well and rock salt in the raw material salts is not zero. The production process provided by the invention can replace the sea salt with the well and rock salt to improve production capacity and reduce cost. 本发明公开了种用井矿盐代替日晒海盐精制二次盐水的生产工艺，采用日晒海盐精制二次盐水的生产工艺，以海盐和井矿盐作为原料盐，其中，原料盐中海盐的质量分数不小于25％，且原料盐中井矿盐的含量不为0。本发明能够将用于井矿盐代替海盐提高产能降低成本。
