You could make this zone as thick as you wish. And if your closure plan calls for a protective layer over this, you could stop adding clay for the final layers.

WebSRK Consulting identified three geochemical zones with depth beneath the tailings beach: • Surficial zone of active oxidation and secondary product precipitation, within about 6 m of the surface, comprising desiccated or drained tailings of pH 6.5 to 7.5, sulphate reducing with depth from about 250 mg/l towards the surface, and electrical … A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive. Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth. The Syn…
