2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.

This work is part of the ongoing development of the attrition-leaching carbonation process, a single-step aqueous carbonation technology that integrates a stirred bead mill. The principle of the attrition-leaching carbonation process is to continuously refresh the surfaces of reactive particles so that leaching can proceed unimpeded, yielding enhanced carbonation …

hammer mills may also be able to process materials with low melting points for coarse grinding applications. Explosibility. The risk of dust explosions must be taken into account when a material is ground very fine in a milling process. Dust-laden air can give rise to devastating dust explosions. Unless the material is one of the few commonly

During the milling process, nickel atoms can dissolve in the amorphous matrix by diffusion due to severe deformation. The existence of "free volume" in the melt-spun amorphous phase may favour the diffusion of nickel atoms. At the same time, the elemental atoms (such as iron) in the amorphous phase may also dissolve into the nickel matrix.

In this process, the precipitation efficiency of heavy metal ions in the solution was largely affected by the activated degree of the raw CaCO 3, which is closely related to the rotation speed of ball milling.Accordingly, the removal results at different mill speeds from 0 to 400 rpm were shown in Fig. 1(a). Without wet ball milling (0 rpm), the lead-containing mixed solution …

contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This problem can be overcome by using depressants like car-boxymethylcellulose (CMC) and guargum deriva-tives, although their cost accounts for as much as
