  • Method and device for separating materials
    Patent number: 7090082
    Abstract: A method for separating materials, in which a mixture of materials is guided through a channel in a direction of flow that extends at least approximately parallel to the gravitational field. Utilizing a wash fluid conveyed through the channel in a direction transverse to the direction of flow of the mixture of materials, at least one material component of the mixture of materials that is to be separated is displaced from the mixture of materials and removed from the channel. A device is also provided that is particularly suitable for carrying out the method.
