A process for the beneficiation of trona includes supplying a trona feedstream that is crushed and dried. The trona is then separated into a first size fraction and a second size fraction. Impurities are removed from the first size fraction using at least one magnetic separator. The magnetic separator includes a plurality of stages. Each stage includes a conveyor system comprising a first end, a second end, and a conveyor belt. Each stage also includes a magnetic roller disposed at the second end of the conveyor system and a splitter disposed adjacent the second end of the system for separating a fraction of magnetic impurities from the trona to create a beneficiated fraction. At least one conveyor belt is deionized. Airborne dust particles are removed from an area surrounding at least one conveyor system.
