Erosion, the process of removal of rockwaste, will be discussed in later chapters.
侵蚀作用，也就是岩屑的迁移作用，将在后面几章中讨论。

Dr Scott argues that underwater mining will be far less disruptive to the environment than terrestrial mining: there will be no piles of wasterock, since the deposits are directly on the sea floor.
The open pit areas are surrounded by an array of sculpted tailings ponds and mine dump areas; these receive mine wasterock for storage and later leaching for further recovery of metals.
