PTMS MAGNETIC SEPARATION iron removal is energy-efficient and highly effective, making it ideal for open-pit sand mines with high daily processing capacity and stable ore grade. However, the situation becomes significantly more complex for hard rock potassium feldspar ores (unweathered granite or pegmatite). These ores typically require a complete three-stage crushing and ball milling process to achieve the desired liberation particle size, generally with over 80% of particles below-0.074mm.

PTMS MAGNETIC SEPARATION

During this process, not only is the primary ore sludge further crushed, but a significant amount of secondary ore sludge is also generated through mechanical grinding. Therefore, PTMS MAGNETIC SEPARATION iron removal must be scheduled after closed-circuit grinding and classification operations, serving as the final purification step before flotation. The common practice is: the grinding discharge first enters a high-frequency fine screen or hydraulic PTMS MAGNETIC SEPARATION for classification.

The overflow portion (rich in fine mud) is directly fed into the decanter or thickener hydrocyclone for deep dewatering, while the underflow is adjusted in concentration and pumped to the flotation PTMS MAGNETIC SEPARATION system. If the plant employs amine-based reverse flotation (using cationic collectors to remove quartz and gangue, with potassium feldspar concentrate remaining in the tank), the iron removal requirements become particularly stringent.
