dry iron removal equipment

At a high-grade kaolin petrochemical granite mining area, we developed an integrated process combining "three-stage crushing, wet rod milling, reverse flotation for mica removal, high-gradient PTMS MAGNETIC SEPARATION, oxalic acid leaching, and ultrasonic cleaning". This system successfully reduced the iron oxide content (Fe₂O₃) from 0.52% to 0.06%, while enhancing whiteness to over 86%, meeting the requirements for premium ceramic glazes. For example, in flotation processes, pH levels directly influence the adsorption behavior of collectors on mineral surfaces.

PTMS MAGNETIC SEPARATION

The success of this multi-stage collaborative PTMS MAGNETIC SEPARATION iron removal strategy hinges on seamless coordination across all phases: the grinding fineness must sufficiently disintegrate valuable minerals without causing excessive pulverization that leads to sludge formation; flotation reagent selection must balance selectivity and capture efficiency to prevent feldspar loss. The process emphasizes precise control of critical parameters.

what is magnetic separation？

At pH <3, dodecylamine exists as RNH₃⁺, which binds more readily to the negatively charged mica surface. Within the pH range of 6 to 8, fatty acid-based collectors demonstrate peak activity, making them ideal for removing carbonate impurities such as calcite. Through orthogonal experimental design (L9(3⁴)), we systematically evaluate the influence of four factors—pH, reagent concentration, stirring time, and aeration rate—on recovery efficiency. This approach establishes a response surface model for PTMS MAGNETIC SEPARATION to predict optimal operating conditions.
