Abstract

The present invention relates to an apparatus for manufacturing a potassium compound and a method of recovering a potassium compound from a brine, and provides the apparatus for manufacturing the potassium compound, including: a continuous pre-treatment apparatus including a crushing portion, a pulverization portion, and a particle size separation portion for processing a mixed raw material salt obtained after lithium, magnesium, and calcium are extracted from a brine to have a particle size for easy separation and sorting; a continuous potassium compound lump recovering apparatus continuously separating and recovering the potassium compound from the pre-treated mixed raw material salt; a continuous potassium compound separating and sorting apparatus continuously separating and sorting potassium chloride and a glaserite (NaSO.3KSO) from the recovered potassium compound; and a continuous potassium sulfate conversion apparatus extracting potassium sulfate from the separated glaserite.
