copper flotation process

The Flotation Process In the case of copper minerals the particles adhere to this froth which is separated whereas the great bulk of the useless material sinks to the bottom of the tanks By varying the chemical conditions within the cells different results can be obtained thereby making flotation highly selective in skilled hands
