The chemical composition of nickel laterites NA and NB from Philippines and Indonesia, respectively, used in this study, was assayed quantificationally by according to the Chinese non-ferrous metal industry standard YS/T 820–2012 combined with the Chinese standard GB/T 14506–2010, and the results are presented in Table 1. Table 1 shows that sample NA contains 1.29 wt% Ni, 16.31 wt% Fe, 27 ...
2017-9-22 · and the saggers are cleaned from ash, limestone and coke breeze in order to get ready for recharging with iron ore and reduction mix. After the tube-like sponge iron cake has been cleaned from ash and adhering coke breeze it goes through several crushing stations. The first step is coarse crushing to facilitate additional crushing stations.
White corundum The hardness of white corundum is slightly higher than that of brown corundum, but the toughness is slightly worse. It is easy to cut into the workpiece when grinding. It has good self-sharpness, small heat generation, strong grinding ability, high efficiency and higher price than brown corundum. Production Process Alumina powder → electrolytic smelting → crushing ...
