Abstract

Предложен способ удаления гипса из кальцийсодержащего материала, включающий охлаждение кальцийсодержащего продуктивного выщелачивающего раствора (10) путем косвенного контактирования кальцийсодержащего продуктивного выщелачивающего раствора (10) с обедненным гипсом продуктивным выщелачивающим раствором (11), с получением охлажденного продуктивного выщелачивающего раствора (19). Охлажденный продуктивный выщелачивающий раствор (19) охлаждают в охлаждающем устройстве (13) для получения дополнительно охлажденного продуктивного выщелачивающего раствора (12). Гипс осаждается из дополнительно охлажденного продуктивного выщелачивающего раствора (12) с получением обедненного гипсом продуктивного выщелачивающего раствора (11).
