From the above, it can be seen that the initially present interfering earth alkali content, i.e., the 1.5 percent anhydrite and kieserite following treatment with the anti-caking agent and separation in an electrostatic field results in a concentrate removed at the cathode which in all cases contains under 0.5 percent and preferably under 0.2 ...

Anhydrite is a mineral—anhydrous calcium sulfate, CaSO 4. It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry . It is not isomorphous with the orthorhombic barium ( baryte ) and strontium ( celestine ) sulfates, as might be expected from the chemical formulas.
