A new clean process for barium carbonate preparation by ...

2008-9-1  Barium carbonate is an important industrial material. Conventional method of BaCO 3 preparation is based on high-temperature reduction of barite (natural barium sulfate) with coal, which produces a great amount of CO 2 (greenhouse gas). This research offers a clean method for BaCO 3 production with methane as the reducing agent, which decreases the CO 2 emission considerably (up
