41. A method for treating a stream, the stream including liquid, and the stream flowable,
the stream having material therein, the material comprising first material and second material, the first material comprising particles of a first size with a first largest dimension, and the second material comprising particles of a second size with a second a second largest dimension, the first largest dimension being smaller than the second largest dimension, the method comprising flowing the stream to a system, the system Including a tube, the tube having an Interior surface, the tube having a first end and a second end, the tube inclined with the first end higher than the second end so that the stream is flowable through the tube from the first end to the second end and out from the second end aided by gravity, jetting water Into the stream within the tube, the jetting water moving the stream around within the tube to facilitate working of the materials of the stream within the tube, and inhibiting with the jetting water the stream from flowing aided by gravity, said inhibiting maintaining the stream within the tube for a period of time to prolong working of the material within the tube, wherein the system further comprises a top plurality of water inlets on top of the tube and a bottom plurality of water inlets on the bottom of the tube, the top plurality of water inlets opposed to the bottom plurality of water inlets, the method further comprising jetting water through the top plurality of water inlets and simultaneously jetting water through the bottom plurality of water inlets to enhance the working of the material within the tube.

50. A method for treating a stream, the stream including liquid, and the stream flowable,
the stream having material therein, the material comprising first material and second material, the first material comprising particles of a first size with a first largest dimension, and the second material comprising particles of a second size with a second a second largest dimension, the first largest dimension being smaller than the second largest dimension, the method further comprising flowing the stream to a system, the system including a tube and screening apparatus, jetting water into the tube to work the material in the stream within the tube producing an intermediate stream with the material and jetting water, flowing the intermediate stream to the screening apparatus, separating, with the screening apparatus, the first material from the second material, the second material unable to pass through the screening apparatus and the first material passing through the screening apparatus, wherein the system further comprises water application apparatus for applying water on the screen apparatus, the method further comprising applying water on the screening apparatus into material flowing down the screen, the application of the water inhibiting downwardly flow of material down the screening apparatus and prolonging the material on the screening apparatus for a period of time.

56. A method for treating a stream, the stream including liquid, and the stream flowable,
the stream having material therein, the material comprising first material and second material, the first material comprising particles of a first size with a first largest dimension, and the second material comprising particles of a second size with a second a second largest dimension, the first largest dimension being smaller than the second largest dimension, the method further comprising flowing the stream to a system, the system including a tube and screening apparatus, jetting water into the tube to work the material in the stream within the tube producing an intermediate stream with the material and jetting water, flowing the intermediate stream to the screening apparatus, separating, with the screening apparatus, the first material from the second material, the second material unable to pass through the screening apparatus and the first material passing through the screening apparatus, wherein the system further comprises a top plurality of water inlets on top of the tube and a bottom plurality of water inlets on the bottom of the tube, the top plurality of water inlets opposed to the bottom plurality of water inlets, the method further comprising jetting water through the top plurality of water inlets and simultaneously jetting water through the bottom plurality of water inlets to enhance the working of the material within the tube, wherein at least a portion of the interior surface of the tube is lined with a liner, the method further comprising flowing the material to contact the liner to enhance working of the material.
