The determination of the “optimum pit limit” of a mine is considered to be a fundamental problem in mine planning as it provides information which is essential in the evaluation of the economic potential of a mineral deposit, and in the formulation of long-, intermediate-, and short-range mine plans. A number of mathematical techniques have been proposed to solve this problem, some of the more ...
Scientists from the U.S. Geological Survey are evaluating the potential for undiscovered sulfide deposits containing varying amounts of nickel, copper, platinumgroup metals, and cobalt in the Lake Superior region as part of an ongoing effort to assess the mineral potential of the United States. Similarities between rocks of the Midcontinent rift and rocks that host the Voisey Bay nickel-copper-...
Marine hydrothermal microorganisms respond rapidly to changes in the concentrations and availability of metals within their environment. Hyperthermophilic archaea appear to possess novel mechanisms for metal detoxification, dissimilatory metal reduction and metal assimilation that may be absent in their mesophilic and bacterial counterparts. For example, tungsten was found in high concentration...
ناحیه شمال غرب ایران یکی از مناطق شناخته شده از لحاظ وجود اندیسای مس می باشد. در قسمت شمالی استان آذربایجان شرقی رخنمونهایی از اندیس های مس دیده می شوند. وجود تشکیلات آهکی در اطراف این توده ها زیمنه مناسبی جهت ایجاد تمرکز هایی از تیپ اسکارن فراهم آورده است. کانسار مس مزرعه یکی از کانسارهای اسکارن مس موجود در سری شیور داغ می باشد. به منظور انجام این پروژه ابتدا به مطالعه ساختاری منطقه پرداخته شد...
