Outotec Gypsum Removal Plant Unit - Complete solution for controlled gypsum removal in a wide variety of process applications

Combination of proprietary equipment and process expertise improves end-product quality while minimizing downtime, emissions, and costs. 

The Outotec Gypsum Removal Plant Unit is a complete solution for controlled gypsum removal when treating calcium-saturated process solutions. Its unique combination of Outotec proprietary equipment and process expertise make it the industry benchmark, with a proven track record of long-lasting operation in even the most challenging conditions.

Typically used in hydrometallurgical zinc, copper, and nickel refineries, gypsum removal is achieved by cooling the solution and precipitating the gypsum into particles suitable for thickening. This minimizes the common problem of gypsum scaling in process pipes and other equipment downstream.

We offer a comprehensive range of proprietary equipment, including the compact Outotec® Cooling Tower for reduced plant footprint and emissions, proven Outotec OKTOP® reactors for solution homogenization, and Outotec® High Rate Thickener technology for separating precipitate. Customers can take advantage of our full range of support services, including engineering, delivery, and process guarantees.
