Denver, Colo., assignors, by direct and mesne assignments, to American Factors Associates, Limited, Honolulu, Hawaii, a corporation of Delaware Filed Nov. 14, 1962, Ser. No. 237,575 13 Claims. (Cl. 3127-45) 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.
More specifically, 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.
In processes of this type which employ solvent as the liquid extracting medium it necessarily follows that recovery of the soluble substance free from the solvent requires subsequent separation of the two, which is a costly procedure. Accordingly, an objective for an improvement in this art is that of securing the removal and recovery of the maximum quantity of soluble substance while employing for that purpose the smallest possible amount of solvent. y Theoretically the counter-current relative movement of the solid material and the solvent is well suited to diffusion, leaching, and lixiviation procedures, and good practical usage has been made of such practice in the past. However, as far as these applicants know all prior art procedures of this general type which have employed counter-current relative movement between the solids and solvent to effect such extraction have left a great deal to be desired from the standpoint of providing a procedure which employs a solids and solvent relationship which adequately approaches the ideal for the most efficient ex- Theoretically, the greatest efficiency would be achieved, other circumstances permitting, if each drop of the liquid solvent were brought successively into diffusing, leaching, or lixiviating contact with each particle of the solid material, in that sequence or order establishing a true counter-current flow therebetween.
Whereas such an ideal operation is desirable in principle it poses an impossible problem from the practical standpoint, but, at the same time, it is to be understood that in this art improvement does lie in the direction of approaching as closely as possible the theoretically idealv 3,248,263 Patented Apr. 26, 11966 having substantially uniform bulk density and permeability throughout, said mass having its length extending horizontally, preferably on the circumference of a circle, but on a straight or other line if desired, its width defined by vertical side faces and its depth maintained at all times at a substantially constant dimension with the upper face thereof constituting a substantially horizontal even surface disposed at a level which gives to said mass a depth dimension of substantial magnitude. It is to be understood, however, that the solid material will become slightly compacted as it travels through the treatment zones, and to this extent the bulk density and permeability thereof will be slightly altered.
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. Such relative movement not only would continuously agitate and disturb the uniform character and disposition of the mass itself, thus producing channeling or other unwanted actions, but would also disturb the relatively quiescent downward movement of the solvent in a manner detrimental to the high eiiiciency resulting from this invention and, in addition, would prevent the successful practice of clarification procedures, hereinafter more fully explained, contemplated for this invention.
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.
In addition, 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. In addition, the zones of treatment are determined solely bythe control of the supply of liquid solvent employed and not by partitions intersecting the mass. In other words, 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. Thus the continuous character of the mass renders it free from channeling or any tendencies which would interfere with the uniform iiow, associa-
