How Ultrafine Grinding Enhances the Industrial Added Value of Barite?
Barite (mainly composed of BaSO₄) is an important non-metallic mineral resource. Barite is characterized by its high specific gravity (4.2–4.6), strong chemical inertness, acid and alkali resistance, and non-toxicity. Traditionally, about 80–90% of barite is used as a weighting agent in oil and gas drilling fluids. The remaining portion is applied as a chemical raw […]
