Definitions

  • This invention relates to a new and improved process for removing or extracting, by the use of a suitable solvent or solvents, soluble substances from subdivided solids by diffusion, leaching, or lixiviation.
  • This invention also relates to new and improved apparatus which is especially adapted for use in carrying out the process of this invention.
  • the process and apparatus of this invention are designed to carry out the removing and extracting procedure of the type referred to by a continuous operation, as distinguished from a bath operation, and to effect such removal or extraction by employing an essentially counter-current liow or movement between the mass of subdivided solid material undergoing treatment and the extracting solvent or solvents employed.
  • the process of this invention provides for the close lateral confinement of the side faces of said mass without frictional or other disturbance.
  • the apparatus of this invention provides for closely contacting confining side walls immediately adjacent the side faces of said mass to contain the solvent placed thereon without relative movement between the side walls and said mass, for confining the solvent to the desired downward travel throughout said mass without channeling or otherwise undergoing non-uniform ilow action.
  • the downward flow of the solvent is therefore characterized as being carried out without disturbance or movement of the material of said mass such as would result from a relative sliding movement between the containing side walls and the mass itself.
  • the process and apparatus of this invention accordingly provide for the continuous application of fresh subdivided solid material at one end of said mass and the continuous removal, at a corresponding rate, of spent solid material from the other end of said mass, while at all times maintaining conditions which will cause the material of said mass to be deposited in a condition of substantially uniform bulk density and permeability with a substantially level and even top surface and in close non-channeling and supported contact with the side walls.
  • the process and apparatus of this invention provide for the desired gravitational passage of the solvent liquid through a limited and particular zone or portion of the mass so that fresh liquid rst encounters the most spent material and also in such manner that the continuous stream of liquid fed to the top of said zone or portion of said mass comes in contact for diffusing, leaching, or lixiviating activity with a vertical column of said mass of substantial depth but of relatively small cross-sectional area.
  • the zones of treatment are determined solely bythe control of the supply of liquid solvent employed and not by partitions intersecting the mass.
  • this invention provides that the mass from end to end shall be continuous, uninterrupted, and uniform and thus free of dividing walls or partitions or any other similar structures such as would create pockets or corners or other spaces that will not uniformly fill as required.
  • the continuous character of the mass renders it free from channeling or any tendencies which would interfere with the uniform iiow, associa-
