Chemical leaching with PTMS MAGNETIC SEPARATION technology stands out for its efficiency and thoroughness in processing high-iron ores or challenging minerals. However, persistent industry challenges include equipment corrosion from acid/alkali reactions, wastewater discharge pollution, and kaolinite structural damage. Current optimization efforts focus on "precision control" and "green alternatives" to address these issues.
Taking the acid leaching process as an example, while traditional prolonged immersion with concentrated acids effectively dissolves iron and titanium oxides, it often causes disintegration of kaolinite's layered structure, leading to aluminum leaching and reduced product performance. Modern optimized PTMS MAGNETIC SEPARATION strategies emphasize precise parameter control: using 3-5% low-concentration hydrochloric acid under mild heating conditions of 60-80℃ for staged leaching.
This system ensures effective dissolution of Fe³⁺ while maximizing mineral crystal integrity. The closed-loop process system of "acid leaching-washing-neutralization-PTMS MAGNETIC SEPARATION" recycles wash water for dilution in earlier stages, centrally recovers neutralized precipitates (e.g., iron hydroxide), and converts waste acid into calcium chloride byproducts through lime milk neutralization, achieving near-zero wastewater discharge.
