With the depletion of high-grade manganese ores, Mn ore tailings are considered valuable secondary resources. In this study, a process combining high-gradient magnetic separation (HGMS) with hydrometallurgical methods is proposed to recycle fine-grained Mn tailings. The Mn tailings were treated by HGMS at 12,500 G to obtain a Mn concentrate of …
Chromium ore processing residue (COPR) is a hazardous waste generated during the production of chromate. Currently, approximately 10% of Cr 2 O 3 cannot be extracted after chromite sodium roasting and remains in COPR, wasting valuable Cr resources. In this study, Mg was selectively removed by using (NH 4) 2 SO 4 roasting in combination with H 2 SO 4 …
2. 0 g of IOT were dispersed in 30 mL of sodium silicate solution (0.015 M), and then 30 mL of magnesium sulfate solution (0.015 M) was added dropwise to obtain an off-white mixture. Afterwards, PST added to the mixture to obtain a new suspension. Then, the suspension was hydrothermally treated at 180 °C for a certain time in a Teflon-lined autoclave.
