    Mining: Barite mining in Missouri began around 1850; however, early lead mining operations began as early as 1725 in the same area, but barite was cast aside as a waste product at that time. Barite production data has been recorded from 1872 to present. The Washington County deposit is the major source of Missouri’s barite production.
