Copper oxide coating onto electric conductive iron particles was carried out. We have proposed a macroscopic method to examine the coating state by measuring the specific resistance of a pallet made out of coated particles. We have also performed a mass balance analysis of feed and coated particles, and X-ray diffraction analysis. Since iron and copper oxide were distinguishable by secondary electron images and backscattered electron composition images, we have investigated the microscopic cross section of the pellets and evaluated the insulation state qualitatively. Macroscopic evaluation of the coating state obtained by measurement of the specific resistance was also validated by another investigation.
