Mining, minerals and metal winning

Demanding tasks need customized solutions. As trivial as a valve may seem, it is often the tiny inconspicuous details that determine human and environmental safety as well as the operating costs incurred or the process yield.

One of GEMÜ's strengths as a valve manufacturer is that it offers customized process solutions which join the valve with the actuator and sensor system as an integral unit, well adapted to the occurring working conditions. Where solids and slurries are involved, mechanical wear (abrasion) and deposits (scaling) in the system is often a cause of failures. When hydro-metallurgical processes such as heap leaching, solvent extraction SX/EW, adsorption on activated coal (CIC, CIL, CIP, Merrill-Crowe® etc.), flotation, thickening are used, aspects like corrosion may affect the process. Roasting, smelting and other pyro-metallurgical metal-wining methods are facing high temperatures and very corrosive situations at the same time.
