摘要

PROBLEM TO BE SOLVED: To advantageously reutilize flux residue based on an alkali metallic fluoroaluminate or an alkali metallic fluorozincate by adding the flux residue to fluorite in the production of hydrogen fluoride and CaSO₄ from fluorite and oleum. ;SOLUTION: Flux residue based on fluoroaluminate of potassium and/or cesium is used by 2 wt.%, advantageously 0.35-1 wt.% of the dry weight of fluorite contg. the flux residue preferably in a water-free state. Flux residue based on an alkali metallic fluoroaluminate and additionally contg. an alkali metallic fluorosilicate and/or an alkali metallic fluorozincate may be used. Hard gypsum having an additional cation content originating from the use of flux residue based on potassium fluoroaluminate and/or potassium fluorozincate is advantageous.;COPYRIGHT: (C)1999,JPO
