2015-1-1 Peixoto (1993) also used a static leaching process to treat pellets and sinter produced from an iron ore with a thermal treatment at above 1200 °C. Pellets containing 0.029% P gave a product with 0.019% P after leaching with 10% HCl while sinter with 0.060% P was leached to a level of 0.046% P.

2020-3-3 2.Kaolin Magnetic Separation. Almost all kaolin raw ore contains a small amount of iron minerals, generally 0.5% -3%, mainly including colored impurities such as magnetite, ilmenite, siderite, and pyrite. The magnetic separation method mainly uses these magnetic differences between gangue minerals and kaolin to remove these colored impurities.
