Abstract

= 7) of ≤4.84% for all three phases. The standard addition method was applied for recovery testing, with recovery rates ranging from 90.5% to 98.0%. This method enables the separation and continuous determination of calcium sulphate, calcium carbonate, and calcium fluoride phases. With a straightforward process and efficient operation, it saves time, labor, and costs, thereby significantly enhancing analytical efficiency. The technique is particularly applicable for phase analysis of calcium in gypsum-associated fluorite ores.
