1 Scope

This method specifies tantalum iron, determination of the content of water in the wet ferro-niobium concentrate. This method is suitable for iron, tantalum, niobium iron ore in measured hygroscopic water. Measurement range. 0.10 to 5.00%.

2 Method summary

The sample was 105 ℃ ~ 110 ℃ drying, with the reduction method to calculate wet storage level.

3 Instrument

Ovens.

4 Sample

Samples should be placed in a sealed container, isolated from the air. Step 5 Analysis 5.1 Sample Weighed 100.0g sample (4), accurate to 0.001g. 5.2 Determination of the number of Two independent measurement averaged. 5.3 Determination A sample (5.1) is placed in advance at 105 ℃ ~ 110 ℃ drying to constant weight weighing dish. In a thermostatic oven at 105 ℃ ~ 110 ℃ Drying 2h. Removed, placed in the dryer cooled to room temperature weigh, and repeatedly drying to constant weight. NOTE. Before weighing dish containing a sample to be dried in the oven thermostat 1h. Removed, placed in a drying dish. Cool to room temperature (about 30min), weighed, and is repeated Row to constant weight. Calculation results of the analysis of 6 The content of water in the trap wet wet mass fraction w (H2O) and its value is expressed in%, according to equation (1). w (H2O) = (M1-m2) (M1-m0) × 100 (1)
