Green's Processing Mill

Map Ref SN

The Green's Processing Mill. The property appears to have been in the possession of George Green of Aberystwyth for a short time. Green (1824-1895) owned the Cambrian Foundry, and supplied mining equipment to mines in mid-Wales and further afield. Green patented his "self-acting dressing machinery", which included crusher rolls, jiggers, buddies and classifiers, installed in purpose-built mills, which were powered by water wheels. The remains of the Green's processing mill survive at Nantgarw, although they are difficult to interpret.

The Leats

Three leats for the mine, the shortest one running from Nant Y Carw stream which may of had a dam built across the stream. The longest leat was constructed in 1893 to carry water from LLyn Carw 2km to the west.
