鉱石の単体分離分析における2次元–3次元間の誤差

Two-dimensional (2D) analytical assessment of mineral liberation from ore particles, such as scanning electron microscope and energy dispersive X-ray (SEM/EDX)-based analysis of particle sections, results in stereological bias compared to the actual three-dimensional (3D) mineral liberation. Thus, a simulation-based stereological correction method for accurate assessment of mineral liberation was developed. The method utilizes a pre-established database of numerically simulated binary particles to estimate 3D composition distributions based solely on measurable 2D composition distributions. Notable features of the method include the relatively small amount of 2D-distribution input data required, and the rapidity of the analysis. The method is also suitable for post analysis of SEM/EDX-based particle sectional liberation analysis.
