Evaporation Crystallization
LEACHING PROCESS
The leaching process converts valuable metals in raw material into water-soluble ions using acidic or alkaline lixiviants.
- Reactor
- Lixiviant
- Leaching conditions (Temperature ,Solid-liquid ratio, Reaction time, Agitation speed)
SOLID-LIQUID SEPARATION PROCESS
By selecting appropriate solid-liquid separation equipment, the leached slurry mixture is effectively separated to obtain clear and transparent filtrate.
- Types of solid-liquid separation equipment
- Separation precision of solid-liquid separation
- Efficiency of solid-liquid separation
LIQUID-LIQUID SEPARATION PROCESS
Using the filtrate from solid-liquid separation as the feedstock, appropriate liquid-liquid separation equipment and purification processes are selected to obtain a purified salt solution.
- Types of liquid-liquid separation equipment（such as mixer-settlers, centrifugal extractors, extraction columns, ion exchange columns, etc. ）
- Separation and purification process
EVAPORATION CRYSTALLIZATION PROCESS
Using the purified salt solution obtained from liquid-liquid separation as feedstock, appropriate evaporation-crystallization equipment and processes are selected to produce purified crystalline salt products.
- Types of evaporation-crystallization equipment
