A fast, accurate and reliable instrument for measuring the magnetite content in samples.
Accurate measurement of ferrous material content in iron ore is extremely difficult and time-consuming by conventional chemical methods in the laboratory. This is overcome by measuring the total magnetic moment of the sample in a high magnetic field thereby measuring the magnetite content in the sample accurately, reliably and faster than measurement based on susceptibility of the material.
For over 40 years Satmagan has been in use in the mining industry around the world and has been proven to be a fast, accurate and reliable instrument for measuring the magnetite content in samples. With a measuring time of roughly one minute and an accuracy of 0.4 % or less Satmagan is considered to be an ideal instrument for securing an optimal return on investment.
The principle behind the Satmagan 135 is to measure the force acting on the sample in a magnetic field with a spatial gradient. The magnetic field is strong enough to saturate the magnetic component in a sample. A Satmagan can be used to measure any sample with only one magnetic component. Alternatively, it can measure a component with a dominant concentration and/or dominant specific magnetic moment.
Once Satmagan is calibrated it is easy and fast to use. Therefore it is an ideal instrument for analyzing mixtures of magnetic and non-magnetic components.

Powder, Granular Or Solid Samples Used For The Measurement
Stabilized For Voltage And Temperature
Applications
The Satmagan was designed especially to measure magnetite in iron ore concentrations. It can be used in various applications:
Analysis of magnetite in iron ores, concentrates and tailings.
Control of copper and nickel smelting by analyzing magnetite and other ferromagnetic oxides in slag.
Determination of martensite or ferrite in austenitic steels.
Determination retained austenite in steels.
Control of magnetizing roasting.
Control of oxidizing roasting of carbonate ores.
Controlling the heat hardening of pellets.
Control of iron ore sintering.
Materials for Analyses
Magnetite and magnetic iron can be analyzed. The sample can contain only one magnetic component, or have one component with a dominant concentration and/or specific magnetic moment.
Type of Sample
Powder, granular or solid samples maximum volume of sample 1.2 cu cm (0.073 cu inch) recommended sample size: sample container filled up grain size: An average grain size greater than 150um (100 mesh) does not disturb the measurements. For finer materials, the Satmagan gives slightly lower readings, so a different calibration curve is required.
The Range of Measurement
Fine Range: 0 to 100 % by magnetite weight .
Course Range: 0 to 200 % by magnetite weight for stronger magnetic materials.
