CO OZNACZA SŁOWO TAILINGS
Odpadki
Odpady, nazywane kopalniami kopalni, wysypiskami śluzu, szlamami, ogonami, odpadami, pozostałościami po ługowaniu lub ślinkami są materiałami pozostawionymi po procesie oddzielania cennej frakcji od nieekonomicznej frakcji rudy. Odpady różnią się od nadpodłogów, czyli skał odpadowych lub materiałów nałożonych na rudę lub ciało mineralne, które są przemieszczane podczas wydobycia bez przetwarzania. Wydobywanie minerałów z rudy można wykonać na dwa sposoby: wydobywanie na placerze, wykorzystujące wodę i grawitację w celu wydobycia cennych minerałów lub wydobycia twardego skała, które wykorzystuje rozpylanie skał, a następnie chemikaliów. W tym ostatnim wydobywaniu minerałów z rudy wymaga się, aby ruda została uziemiona w drobne cząstki, więc odpady z odpadów zwykle są niewielkie i mają rozmiar od ziarna piasku do kilku mikrometrów. Odpady z kopalni są zwykle produkowane z młyna w formie szlamu. W niektórych sytuacjach odpady odlewania stanowią zewnętrzny koszt wydobycia. Dotyczy to przede wszystkim wczesnych operacji wydobywczych, które nie podjęły odpowiednich kroków w celu uczynienia obszarów poletniczych bezpiecznych dla środowiska po ich zamknięciu.
Definicja słowa tailings w słowniku
