magnetic separator for feldspar

In the acid leaching iron removal process of PTMS MAGNETIC SEPARATION, the combined use of H₂SO₄ and H₂O₂ leverages hydrogen peroxide's reducing power to convert Fe³⁺ into more soluble Fe²⁺ while promoting sulfide decomposition, significantly enhancing acid washing efficiency. After this treatment, Fe₂O₃ in weathered potassium-sodium feldspar ore decreased from an initial 0.45% to 0.03%, with whiteness improving from 78 to 92, making it fully suitable for high-end daily-use porcelain production.

PTMS MAGNETIC SEPARATION

However, the acid leaching process for iron removal in PTMS MAGNETIC SEPARATION must be supported by neutralization sedimentation tanks and resin adsorption units to prevent environmental accidents caused by waste acid discharge. The most noteworthy aspect is the final "combined process". When dealing with complex ores with tight mineral structures that are difficult to process, single-process methods often fail to address all issues effectively. Experimental data from a mining area shows that under the composite reagent system, the iron removal rate increased by 17%, while total reagent consumption decreased by 12%.

what is magnetic separation in Feldspar？

The standard three-stage combined PTMS MAGNETIC SEPARATION process comprises: magnetic pre-selection to remove coarse magnetic particles; reverse flotation to eliminate quartz and mica; and hot acid leaching for iron removal. After implementing this process at a major feldspar base in Inner Mongolia, the product's comprehensive performance reached international advanced standards, with an annual production capacity exceeding 500,000 tons. This achievement established the company as China's first enterprise to achieve mass production of feldspar for photovoltaic glass.
