Development of underground gravity gold processing plants

The Gwynfynydd mill was probably the world‟s first operational underground gold processing plant. It was a static concentration system, which was constructed principally in response to environmental constraints. Development was made easy due to the coarse nature of the gold mineralisation and amenability to gravity concentration.
