The mill was built in 1929 to recover gold, silver, lead, zinc, and copper from ore mined at the Mayflower mine and brought to the mill by an aerial tramway. The mill recovered metals from the ore by gravity separation and by selective flotation.〔(Colorado History )〕 The sulfide ore minerals were concentrated by froth flotation, an innovative method in the early twentieth century that allowed processing of ores that would previously have been too difficult for feasibility. The original mill equipment is still in working order. It is the only intact and functional mill of its kind in Colorado.〔 It was declared a National Historic Landmark in 2000.〔〔Dawn Bunyak (August 25, 1999) (National Historic Landmark Nomination: Shenandoah-Dives Mill / Mayflower Mill ), National Park Service and (Accompanying 32 photos, exterior and interior, from 1932, 1960, and 1995. )〕 The mill is owned by the Silverton Historic Society, which staffs an information and gift shop at the mill under the name Mayflower Mill. The mill is open for self-guided tours in the summer months. ==References== 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「Shenandoah-Dives Mill」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.
