33 Causes, Effects & Solutions for Mining

Effects on plants. Mining can also have severe adverse effects on plants. Plants usually require a certain pH-level to grow. This pH-level is often altered through mining activities. Thus, many plants will no longer grow efficiently and will lose their fertility which may lead to the local extinction of some plant species.Mine Tailings - an overview | ScienceDirect Topics · Mine tailings are the finely ground residue from ore extraction.
