The Common Barite Flotation Processing and Flotation Reagents
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. According to the type of salt-associated minerals, the barite ore can be divided into two categories: barite-quartz-calcite type ore and barite-fluorite type ore. Due to the similar surface chemical properties and similar flotation behavior between barite ore and associated salt minerals, the flotation process and the flotation reagents used in the different barite ores are different. Below, let’s take a look at the flotation process and reagents applied in the above two kinds of barite ore. 01 Flotation used in the barite-quartz-calcite type ore Direct flotation method The flotations used in the barite-quartz-calcite type ore mainly include the following: First,
