ABSTRACT A method of recovering metal values,e.g. gold and silver values from a pulp containing such metal values in dissolved form includes the steps of forming a bed comprising a randon mass of particles of a material such as activated carbon which is capable of removing the metal values from the pulp, in a column having a feed end and a discharge end, and passing a stream of the pulp through the column from the feed end to the discharge end so that the particles of the bed are suspended in a substantially stationary non-fluidised state between the feed end and the discharge end.The stream of pulp is periodically stopped so that the particles of the bed move back toward the feed end of the column.
