OK-R and OK-U Conventional Outokumpu flotation cells

Optional cells for smaller tank volumes

The Outokumpu partnership As one of the world’s leading developers and suppliers of technology, Outokumpu Technology designs and delivers plants, processes and equipment tailored to each customer’s needs. We provide engineering, project and support services for the minerals processing and metallurgical industries globally.

The conventional Outokumpu flotation cells – OK-R and OK-U – include most of the features of the advanced Outokumpu TankCell® units. They are optional to TankCell® units especially for smaller tank volumes (less than 50 m3). The OK-R and OK-U cells operate successfully as roughers, scavengers and cleaners. Standard OK-U cells (from 8 to 50 m3) have internal transversal launders for effective and fast froth handling, and a U-shaped cross section to minimize sanding. Smaller OK-R cells (from 0.5 to 5 m3) have one-sided longitudinal launders and a rectangular cross section.
