Introduction

Introduction and Standard Background

GB/T 6730.7-2016 "Determination of Metallic Iron Content in Iron Ore - Sulfosalicylic Acid Spectrophotometric Method" is the national standard of the People's Republic of China, used to determine the metallic iron content in iron ore, iron concentrate, sintered ore and pelletized ore. This standard replaces GB/T 6730.7-1986 and optimizes and improves the determination method.

Main Contents of the Standard

Spectrophotometer: used to measure absorbance, wavelength is 460 nm.
Magnetic Stirrer: used for magnetic separation of samples.
Volume Flask: includes single-line and graduated pipette, used for solution preparation and quantification.

Comparison table of standard frameworks

Dimensions	GB/T 6730.7-1986	GB/T 6730.7-2016
Measurement range	0.020%~0.300%	Same as above
Reagent preparation	The concentration of sodium salicylate-chloride solution is 2g/100ml	Same as above, the dissolution step is optimized
Operation steps	Includes magnetic separation, leaching, color development and measurement	Added calibration test and waste liquid treatment requirements

Implementation suggestions

Sample collection and preparation:Ensure that the sample particle size is uniform and meets the requirements of GB/T 10322.1.
Reagent preparation:Prepare sodium chloramine-salicylate solution and sulfosalicylic acid solution in strict accordance with the standard to avoid concentration deviation.
Calibration curve drawing:It is recommended to calibrate at least once a month to ensure measurement accuracy.
Waste liquid treatment:Refer to Appendix B and use chromium removal equipment to treat waste liquid to avoid environmental pollution.
