Oct 16, 2019· For the complex disseminated type of barite ore, the barite is often associated with fluorite, calcite, and quartz, which is difficult to be separated by the gravity separation method due to its low grade, fine disseminated grain size, and complex composition. The froth flotation method is the main barite processing method.
