A Novel Approach for Separation and Recovery of Titanium

At present, acidic wastewater is directly neutralized with lime or limestone, which wastes resources such as titanium, scandium, and iron and generates a great deal of solid waste This study proposes a novel approach for the separation and recovery of titanium, scandium, and iron from acidic wastewater and red gypsum utilization The The currently applied methods for impurity removal from phosphogypsum mainly eliminate the influence of phosphorus and fluorine impurities on gypsumbuilding materials 6,7,8,9,10Preparation of gypsum with high purity and whiteness from

Deep removal of phosphorus and synchronous preparation

As shown in Fig 1, the PG sample mainly presented as rhombic flakes with occasional fragmentsThe XRD result (Fig 2) shows that the main component of the PG sample was gypsum (CaSO 4 2H 2 O) with a small amount of brushite (CaHPO 4 2H 2 O) and quartz (SiO 2)The XRF result (Table 1) illustrates that in addition to the main The gypsum concentrate with a whiteness of 692 % and calcium sulphate dihydrate purity of 9724 % was obtained via a simple and efficient method of “highspeed stirring scrubbing, once reverse flotation and once direct flotation” It reached the firstgrade national standard for phosphogypsum building materials in China (GB/T 234562018)Simple and efficient method for purification and recovery of gypsum
