permanent magnetic separator

Feldspar deposits in different mining areas exhibit diverse genesis. Gneiss-type deposits typically feature large crystals with abundant biotite, while weathered granite types show potassium-sodium feldspar enrichment due to prolonged leaching, though iron minerals are distributed as fine disseminated inclusions. Coastal sand deposits, though easily processed, often contain substantial clay and organic matter. The potassium-sodium feldspar PTMS MAGNETIC SEPARATION iron removal closed-loop model

PTMS MAGNETIC SEPARATION

To achieve this, the first step in the iron removal closed-loop process for potassium-sodium feldspar PTMS MAGNETIC SEPARATION is to conduct precise mineralogical analysis. This involves not only standard XRD, XRF, and MLA analyses but also scanning electron microscopy (SEM) observations to determine whether impurity particles exist as independent minerals or as phlogopite-like compounds within the feldspar lattice.

what is magnetic separation in Feldspar ？

When iron primarily exists as hematite inclusions, PTMS MAGNETIC SEPARATION can be effectively separated through strong magnetic separation. However, for lattice iron where Al³⁺ has been replaced by Fe³⁺, acid leaching or even high-temperature roasting becomes necessary for removal. The second step involves designing and integrating the PTMS iron removal process. Modern purification no longer operates as a "single combat" effort, but rather emphasizes "joint operations".
