There are three types of feasibility study used in mining, order of magnitude, preliminary feasibility and detailed feasibility. ==Order of magnitude== Order of magnitude feasibility studies (sometimes referred to as "scoping studies") are an initial financial appraisal of an inferred mineral resource. Depending on the size of the project an order of magnitude study may be carried out by a single individual. It will involve a preliminary mine plan, and are the basis for determining whether to proceed forward with an exploration program, and more detailed engineering work. Order of magnitude studies are developed copying plans and factoring known costs from existing projects completed elsewhere and are accurate to within 40-50%.〔 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「Mining feasibility study」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.
