snrily used nt Dosco, nncl tlie solubility of the contained phosphoric ncid should bo correspondingly incrensed.
Sepnrnte drying of the slng cnu probably lie nvoided by coniplcting tho grnnulntion with the wnter near tlic boiling point, removing the solid slng froin. the tnnk \vhile still hot, nllowitig it to drain it few minutes, nntl transferring it Itot to n suitnblc'grindiug mill, such ns II bnll mill equipped with :in nir-sepnrntion systeni.
