This is because natural slate is a rock – which is not manufactured from other raw materials and any waste generated through production is chemically inert. The natural slate production process starts with the extraction and there are two different approaches: open cast (quarry) and underground (mine).
The Mining Process 1. The slate was extracted (removed) in large blocks or 'clogs'. 2. These were first 'docked' or reduced in size with a chisel and mallet. 3.
