What is ISO 2597 Iron ores — Determination of total iron content?
ISO 2597 provides methods for the determination of the total iron content in iron ores. This standard applies to natural iron ores and processed products that contain at least 1% (mass fraction) of iron.
The standard specifies two methods for the determination of total iron content:
The gravimetric method: This method involves the precipitation of iron as hydroxide and subsequent weighing of the precipitate.
The titrimetric method: This method involves the reduction of iron to the ferrous state, followed by the titration of the ferrous ion with a standard solution of potassium permanganate.
Both methods are suitable for the determination of total iron content in iron ores and can be used independently or in combination with each other.
ISO 2597 provides detailed instructions on sample preparation, testing procedures, calculations, and reporting of results. The standard also specifies the precision and accuracy requirements for the methods.
This standard is essential for the mining and steel industry as the determination of total iron content is critical in the production of iron and steel products.
What is ISO 2597-1:2006 Part 1: Titrimetric method after tin(II) chloride reduction?
ISO 2597-1:2006 is a specific section of the ISO 2597 standard that outlines the titrimetric method after tin(II) chloride reduction for the determination of total iron content in iron ores. This method is one of the two methods outlined in the ISO 2597 standard for determining the total iron content in iron ores, the other being the gravimetric method.
The titrimetric method after tin(II) chloride reduction involves the reduction of iron in a sample to the ferrous state by using tin(II) chloride as a reducing agent. The ferrous ions are then titrated with a standard solution of potassium dichromate.
This method is suitable for the determination of total iron content in iron ores with iron content ranging from 30% to 72%. The sample preparation, testing procedures, calculations, and reporting of results are specified in detail in the standard.
ISO 2597-1:2006 Part 1 also provides information on the precision and accuracy requirements for the method. As well as guidance on the validation of the method for use in a laboratory setting.
Therefore, This standard is important for the mining and steel industry, as the determination of total iron content in iron ores is critical for the efficient production of iron and steel products.
Requirements of ISO 2597-1:2006 Part 1: Titrimetric method after tin(II) chloride reduction
ISO 2597-1:2006 Part 1 outlines the requirements for the titrimetric method after tin(II) chloride reduction for the determination of the total iron content in iron ores. Some of the key requirements specified in the standard include:
Sample preparation: The sample must be properly prepared and homogenized to ensure that it is representative of the entire batch. The particle size of the sample should be between 10 mm and 75 µm.
Equipment: The equipment used for the analysis must be calibrated and validated to ensure accuracy and precision.
Reagents: The reagents used in the analysis must be of high purity, and their concentrations must be accurately known.
Testing procedure: The testing procedure must be followed precisely, including the reduction of iron to the ferrous state using tin(II) chloride. And the subsequent titration of the ferrous ions with a standard solution of potassium dichromate.
Calculation of results: The calculation of results must be performed according to the formula specified in the standard. Taking into account any dilutions that may have been made during the analysis.
Precision and accuracy: The precision and accuracy of the method must be determined, and the results must meet the requirements specified in the standard.
Validation: The method must be validated for use in a laboratory setting, and the validation data must be documented.
So, By following the requirements specified in ISO 2597-1:2006 Part 1, laboratories can ensure that the titrimetric method after tin(II) chloride reduction for the determination of total iron content in iron ores produces accurate and reliable results.
What is ISO 2597-2:2019 Part 2: Titrimetric methods after titanium(III) chloride reduction?
ISO 2597-2:2019 is a specific section of the ISO 2597 standard that outlines the titrimetric methods after titanium(III) chloride reduction for the determination of the total iron content in iron ores. Therefore, This method is one of the two methods outlined in the ISO 2597 standard for determining the total iron content in iron ores, the other being the gravimetric method.
The titrimetric method after titanium(III) chloride reduction involves the reduction of iron in a sample to the ferrous state by using titanium(III) chloride as a reducing agent. The ferrous ions are then titrated with a standard solution of potassium dichromate.
In addition, This method is suitable for the determination of total iron content in iron ores with iron content ranging from 20% to 95%. The sample preparation, testing procedures, calculations, and reporting of results are specified in detail in the standard.
ISO 2597-2 provides information on the precision and accuracy requirements for the method, As well as guidance on the validation of the method for use in a laboratory setting.
This standard is important for the mining and steel industry, as the determination of total iron content in iron ores is critical for the efficient production of iron and steel products.
