2A conceptual framework for characterizing mineralized waste rocks as future resource显示文摘Conventional mining practices do not extract all mineralized rocks due to prevailing economics.Improvement in mineral prices and processing recovery(technology)could potentially make mineralized waste rocks profitable.A well-integrated mining strategy that focuses on both economic and physical resource depletion is vital to the management of non-renewable mineral resources.In this paper,a conceptual framework that maximizes the benefits of mining and processing mineralized waste rocks as future resource is proposed.Governmental policy and technical reforms that ensure mining companies incorporate the proposed mineralized waste rocks management framework in their long-term strategic mine plans have been recommended.Bright Oppong Afum Dylan Caverson Eugene Ben-Awuah 2019International Journal of Mining Science and Technology2019,29,3:3
3Using fuzzy-AHP and parametric technique to assess soil fertility status in Northeast of Iran显示文摘A good understanding of the levels and distribution patterns of soil properties and/or quality indicators is a prerequisite for developing sustainable agricultural land management programs. Traditional assessments of these parameters of soil fertility status are somewhat costly, in both economics and time aspects. Different modelling techniques have been proposed as a useful tool for determination of soil quality indicators and development of soil fertility maps, but to what extent these results are reliable remains under-quantified in many regions worldwide. To address this uncertainty, Fuzzy-Analytical Hierarchy Process(Fuzzy-AHP) and Parametric analyses were conducted to ascertain the soil fertility status of a semiarid region in the Northeast of Iran for some selected crops: alfalfa, corn silage, potato, sugar beet, tomato and wheat. The Fuzzy-AHP and Parametric techniques using soil suitability indices were estimated for each crop and each soil delineation was achieved by Ordinary Kriging. The Technique for Order of Preference by Similarity to Ideal Solution(TOPSIS) was used as a compensatory method to allow tradeoffs among the selected criteria. Our results demonstrated that from the Fuzzy-AHP analysis, the soil fertility indices ranged from moderate to high for production of alfalfa;from low to high for production of corn silage and sugar beet;moderate to high for production of potato and tomato;and from low to moderate for production of wheat. However, the parametric analysis showed soil fertility classes ranging from very low to high for production of all the selected crops. High correlations were also observed between soil fertility indices predicted by both models. Similarly, the capacities of both models to predict soil fertility status for production of the selected crops were also highly correlated. The preference for the cultivation of the selected crops based on the Fuzzy-AHP analysis was sugar beet > corn silage > wheat > alfalfa > tomato > potato. On the other hand, using Parametric techniques, the crops preferences for cultivation ranked as corn silage > wheat > alfalfa > sugar beet > tomato > potato. We concluded that the findings would help to develop sustainable plans of cultivation based on patterns related to soil fertility classes depending on each crop’s requirement.Ali KESHAVARZI Henry Oppong TUFFOUR Ali BAGHERZADEH Leo Paapa TATTRAH Vinod KUMAR Amin GHOLIZADEH Jesús RODRIGO-COMINO 2020Journal of Mountain Science2020,17,4:3
