Optimization of a LaboratoryScale Froth Flotation Process Using

Froth flotation is a universally accepted process for the beneficiation of coal fines. However, the process variables, collector dosage, frother dosage, and pulp density need to be optimized for each coal. In the present work, response surface methodology has been applied for optimization of yield at a desired ash level.
