Scope

Scope: This document specifies the method for determining the amount of calcium fluoride in Baiyun Obo ore. This document is applicable to the determination of the amount of calcium fluoride in Baiyun Obo ore with a silica content ≤ 10% and a phosphorus pentoxide content ≤ 3.50%. The determination range is 5.00% to 40.00%; Main technical content: The sample is leached with a calcium-containing acetic acid solution to extract calcium carbonate, calcium sulfate, free calcium oxide, calcium hydroxide, and some calcium silicate. The leached residue is then leached with an aluminum chloride solution to extract calcium fluoride. The calcium content in the analytical solution is determined by inductively coupled plasma emission spectrometry, and the calcium is converted to the amount of calcium fluoride.
