Foreword
YS/T 360 "ilmenite concentrate chemical analysis method" is divided into six parts.
- Part 1. Determination of titanium dioxide - Ammonium sulfate titration;
- Part 2. Determination of total iron content - Potassium dichromate titration;
- Part 3. Determination of the amount of ferrous oxide - Potassium dichromate titration;
- Part 4. Determination of the amount of alumina - EDTA titration;
- Part 5. Determination of silicon dioxide - Mo - Mo - blue spectrophotometric method;
Part 6. Determination of calcium oxide, magnesium oxide, and phosphorus content - Plasma emission spectrometric method.
This section is part 3 of YS/T 360.
This part replaces the third part of the YS/T 360-1994 "Chemical Analysis Method for Concentrate of Ilmenite (Sand))" (formerly YB878-76)
& Quot; Measurement & quot; and & quot; Determination of Calcium Oxide, Magnesium Oxide. & Quot;
Compared with YS/T 360-1994, the main changes are as follows.
Simultaneous determination of calcium oxide, magnesium oxide and phosphorus in the sample by plasma emission spectrometry (ICP-AES)
--- using platinum crucible sand bath hydrofluoric acid, perchloric acid dissolved samples;
--- increase the repeatability limit.

Chemical analysis of ilmenite concentrates
Part 6. determination of calcium oxide, magnesium oxide and phosphorus
Plasma emission spectrometry
1 Scope
This section specifies the determination of calcium oxide, magnesium oxide, and phosphorus in ilmenite concentrates.
This part is applicable to the determination of calcium oxide, magnesium oxide and phosphorus in ilmenite concentrate. Determination of 0.02% to 2.00% of calcium oxide; oxygen
Magnesium 0.02% ~ 3.00%; phosphorus 0.001% ~ 0.10%.
2 method summary
The sample was dissolved in perchloric acid and hydrofluoric acid in a platinum crucible and heated to take a strong perchlorate. Removed, slightly cold after adding hydrochloric acid dissolved salt,
Diluted to a certain volume. Under certain conditions, with the inductively coupled plasma emission spectrometer, measured at the wavelength of the recommended analysis of Ca,
Mg, P and other elements of the emission intensity, according to the working curve method to calculate the sample of calcium oxide, magnesium oxide, phosphorus, the mass fraction of the determination of
result.
