Abstract

Soluble components in solid material are dissolved continuously in a column comprising one or more stages where the stages are separated by means of perforated plates (2). Solid material and liquid can pass each other countercurrently or cocurrently. The solid material is supplied continuously or periodically to the top of the column at (3) and sinks downwards in the column either by settling through the holes in the plate (or plates) or by hydraulic movement of the current of liquid. The solid material can after the leaching be subjected to a washing process in the lower part of the column or in a separate washing equipment. The ready leached solid material is discharged continuously or batchwise from the bottom of the column, possibly through a separate washing unit. Both the charging and discharging of the solid material can be governed by computer. The leach liquid is pumped into the column from the bottom for countercurrent leaching and from the top for cocurrent leaching. The leach liquid moves in both cases through the length of the column and through the solid material reacting with the latter before it is piped off from the top of the column for countercurrent leaching and from the bottom of the column for cocurrent leaching. <IMAGE>
