MTI uses and distributes a simple, reliable and accurate method for the stereological correction. The method is theoretically based and can be accurately calibrated against reliable and verifiable data in the laboratory.
The demand for stereological correction is brought about by the need to remove the bias introduced by measuring mineral liberation on polished sections of particles in a sample.
This illustrates the bias introduced by sectionning the sample: although the particles are from a narrow size fraction, there "appears" to be particles of all sizes in the picture.
Lcurve analysis to determine which transformation kernel is best suited to the mineral texture considered.
Linear grade distribution for each particle size as measured by image analysis from iron ore particles cross section mounted on the Scanning Electron Microscope.
Volumetric grade distribution after stereological
correction of the above measurements.
A number of transformation kernels for linear and areal measurements are already available. MTI can also develop a transformation kernel for your particular mineral texture and implement it in StereoSoft, making the procedure even more accurate.
