A process for recovering clay from contaminated clay-containing waste materials e.g. drill-cuttings arising from offshore/onshore oil & gas exploration and production processes, comprises a cleaning step to generate a clay of sufficient purity for reuse, and a particle sizing step to obtain a substantially consistent quality clay product optionally in the form of bulk particles or shaped to provide conveniently transportable product forms including granules, pellets, prills, packing elements, briquettes and the like shaped articles. |
