The purity of bischofite. Where does the sediment come from?
Bischofite is extracted by dissolving an ancient salt layer at a depth of 2500 m with water and then pumping out the saturated solution. As it rises through the steel drill pipes, the corrosive salt solution removes the oxide film from the pipes.
- The reddish colour of bischofite is an original product!
- Drying is done immediately to avoid contamination on the surface due to the ability of bischofite to absorb moisture from the air.
- When dissolving with water during the preparation of the solution, the insoluble iron oxide residue acts as an additional adsorbent to remove heavy metal salts from the water (which may be in water)
- The insoluble residue is removed during the preparation of the solution.
