Barite Flotation Separation Process. If barite ore contains a high barium sulfate (BaSO4) content, it is associated with gangue minerals such as quartz, calcite and fluorite. Flotation machine is often required to separate the valuable barite from other minerals present in the ore. The flotation process involves adding reagents to create …
In this work, a novel biodegradable fluorite depressant, tetrasodium iminodisuccinate (IDS) was developed for the flotation separation of barite and fluorite in sodium dodecyl sulfonate (SDSN) system, and its interaction mechanism were revealed. The micro-flotation results proved IDS had a strong depressant on fluorite at pH 6–11.
Flotation use in mineral processing as a critical separation and selective recovery process was first documented in 1905, and the process and equipment have undergone significant changes since then to improve efficacy [].Today, froth flotation technology is widely used in the recovery of many minerals, including (but not limited to) …
