New ElectroStatic Separator Bunting

In many applications, often due to the fine particle size, the ElectroStatic Separator is the only technology that enables a separation (e.g. -2mm granulated cable scrap). The technology also replaces less environmentally friendly separation processes such as froth flotation in mineral processing applications (e.g. separation of rutile from silica sand).
