Tha am mèinnear air ainmeachadh air Uilleam Withering, a dh’ aithnich ann an 1784 gu robh e eadar-dhealaichte gu ceimigeach bho barytes. Tha e a’ nochdadh ann an veins de mhèinn luaidhe aig Hexham ann an Northumberland, Alston ann an Cumbria, Anglezarke, faisg air Chorley ann an Lancashire agus beagan àiteachan eile. Tha Witherite air atharrachadh gu barium sulfate gu furasta le gnìomhachd uisge anns a bheil calcium sulfate ann am fuasgladh agus mar sin bidh criostalan gu tric air an cuairteachadh le barytes. 'S e am prìomh thobar de shalainn barium agus thathar ga mhèinneadh gu mòr ann an Northumberland. Tha e air a chleachdadh airson a bhith a 'deasachadh puinnsean radain, ann a bhith a' dèanamh glainne agus pèileag, agus roimhe seo airson a bhith a 'bleith siùcair.
