Gypsum Beneficiation Wet Process

Beneficiation of Raw Gypsum Ore – 2020 SURP Symposium

The Basics of Drying Gypsum - FEECO

Beneficiation Gypsum drying is a technique used as part of the gypsum beneficiation process. In mineral processing, beneficiation separates the wanted mineral from unwanted material using a variety of processes. Gypsum dryers remove moisture and prepare the mineral for additional steps in the beneficiation process.

Processing and Drying Gypsum

A rotary dryer is used to reduce the moisture content of the gypsum. Lifting flights inside the rotating drum shower the gypsum through a heated air stream, drying the material as it moves through the dryer. Drying is also part of the beneficiation process, separating the
