Slate is a fine-grained, Metamorphic Rock composed of Clay or Volcanic Ash. Slate is ‘cut' into flats sheets of stone that can be sold however this process creates a large volume of waste; up to 90% in some cases.

Slate waste (shards, scalpings, dust and unworkable stone) that has been cast aside once the dressed slate has been prepared is used as a selected fill material in road and rail construction projects and the decorative market is large and with the varied colours, washing makes them a very saleable product.

DUO has installed a 100 tph Washing Plant to process the waste Slate at McAlpine Slate in Bethesda, North Wales.
