Flame atomic absorption spectrometry; Methods for chemical analysis of laterite nickel ores - Part 26: Determination of loss on ignition - Gravimetric method 1 Scope This part of YS/T 820 specifies the gravimetric method for the determination of loss on ignition (LOI) in laterite nickel ore. This part applies to the determination of loss on ignition in laterite nickel ore. The measurement range is 6.00%~14.00%. 2 Method summary Ignite the pre-dried sample to a constant weight at 1000 °C; calculate the loss on ignition (LOI) according to the reduced mass of the sample. 3 Instruments 3.1 High-temperature furnace: the temperature can be controlled at 1000 °C±50 °C. 3.2 Porcelain crucible: make its weight constant at 1000 °C before use. 4 Samples The particle size of the samples shall be less than 160 μm; bake them in an oven at 105 °C~110 °C for 2 h, and cool them to room temperature in a desiccator. 5 Analysis steps 5.1 Sample Weigh 1.00 g sample; the weight shall be accurate to 0.0002 g. 5.2 Number of measurements ......
