ABSTRACT:
There is disclosed a process and plant for cleaning unwashed clay/sand or oil sands in which a vessel having a false floor of permeable material contains a column of liquid and sand to be cleaned in which an air and liquid mix is injected through the permeable material at a controlled pressure so that the air, water and sand clay mixture will mix together to fluidise the sand with the presence of small bubbles of air to create a turbulence and abrasion of the particles and to clean the sand.
