Efficient utilization of lithium and phosphate resources from slag, a byproduct originated product extraction, holds great significance for environmental protection industrial development. Existing methods primarily focus on Li extraction this while PO43- are abandoned. In work, we proposed clean comprehensive approach based impurity followed by sequential precipitation FePO4 Li2CO3, to concurrently recover slag. The results demonstrated an aluminum separation efficiency 85%, reducing the concentration in raffinate below 25.0 mg/L. reaction, facilitated saponification, involved cation exchange between Al3+ Na+. synthesis process FePO4·2H2O was predominantly controlled chemical with activation energy 102.8 kJ/mol. obtained Li2CO3 products met standards battery-grade materials. Notably, achieved remarkable phosphorus recovery rate 98.7% maintaining low loss under 2.0%. This work outlines method achieving complete component recovery, offering guidance efficient environmentally friendly reclamation

An enormous quantity of titanium slag has caused not merely serious environment pollution, but also a huge waste iron and sulfur resources. Hence, recycling resources from recently been an urgent problem. Herein, hematite nanoparticles were fabricated through pyrite reduction approach using as-received as the source reducing agent in nitrogen atmosphere. The physicochemical properties analyzed multiple techniques such X-ray diffraction pattern, ultraviolet–visible spectrophotometry, scanning electron microscopy. best synthesis conditions for found at 550 °C 30 min with mass ratio 14:1 pyrite. results demonstrated that average particle diameter 45 nm nearly spherical shape. specific surface area, pore volume, size estimated according to BET method 19.6 m2/g, 0.117 cm3/g, 0.89 nm, respectively. Meanwhile, possessed weak ferromagnetic behavior good absorbance wavelength range 200 nm-600 applied visible light responsive catalyst. Consequently, these show formed by technique have promising application prospect magnetic material photocatalysis.
