 · Therefore, for barite ore with complex mineral composition, the gravity-flotation or flotation should be adopted. Calcination In the process of mineralization, barite minerals are easy to be mixed with impurities such as Fe2O3, TiO2, and organic matter, which will make barite gray, green or, blue, affect the purity and whiteness of barite, and seriously reduce the

limonite for mining -

Limonite may occur as the cementing material in iron-rich sandstone. Most limonite ore resources are used for making iron, and widely used for pigment material. Limonite mining equipment. In a complete limonite beneficiation production line, it is mainly consists of jaw crusher, ball mill, classifier, magnetic separator, flotation, dryers, etc.

Selective Separation of Fluorite, Barite and Calcite with

Fluorite, barite and calcite are important industry minerals. However, they often co-exist, presenting difficulty in selectively separating them due to their similar surface properties. In this study, valonea extract and sodium fluosilicate were used as depressants to selectively separate them by flotation, with sodium oleate as the collector.
