It is considered to be the most contaminated site in the country, following the cleanup of the former Fruitgrowers Chemical Company site at Mapua, Nelson. ==History== In the 1960s, the Tui mine extracted copper, lead and zinc sulphides.〔 〕 The mine was abandoned in 1973, after the mining company Norpac Mining went bankrupt.〔 Waste, rock ore dumps and mine tailings were left behind. The tailings have significant amounts of zinc and cadmium.〔 The mine tailings are stored behind a dam in a large pool-like area which has an oxidised, solid surface layer.〔 The dam contains over 100,000 cubic metres of very acidic, sulphide-rich, tailings. In 1997, there had been no natural plant recolonisation on the tailings for more than 20 years. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tui mine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
