[60] reported different tungsten tailing deposits, ... the recent advances in the beneficiation circuit and the evolution of new-age instruments have successfully enabled the concentration of ultrafine particles [42, 46, 47, 49, 192 ...
For plants that are prone to rotting, like some euphorbias, amend the soil with 50% pumice, or in lieu of amending the soil, fill the planting hole with pumice so the roots are surrounded by it. Pumice can be used as a topdressing to absorb rainwater that puddles around plants. Create a moat around the plant with vertical tunnels.
For example, a dentist buys his pumice in a small 2-ounce jar. A manufacturer of hand soap or a computer circuit board manufacturer will receive pumice shipments as shrink-wrapped pallets of 44 lb. bags …
