Determination of Occurrence States of Calcium, Magnesium, Phosphorus in Wengfu Phosphorus Tailings by Chemical Phase Analysis
摘要
The contents of calcium, magnesium and phosphorus species in Wengfu Phosphorus Tailings were determined by chemical phase analysis method. The results showed that calcium existed mainly as dolomite with a few as calcite and phosphate, magnesium existed mainly as dolomite with a few as phosphate and silicate and phosphorus existed mainly as phosphate with a few as iron oxides, monazite and xenotime. The results presented a good stability, which indicated that the analytical results of occurrence states of Ca, Mg and P in Wengfu Phosphorus Tailings by chemical phase analysis method were accurate and reliable.
