The emotionalised subject of asbestos is treated in chronological terms: how the "magic mineral" known in ancient times in Europe and Asia became in the late nineteenth century an important industrial resource of particular interest to the navies of the world; and how its malign effects gradually became apparent during the present century. The media have made asbestos a notorious villain, but i...

the purpose of this study is designing a model to determine important factors on export performance (ep) in the base of cost leadership strategy for non_ metal mineral industry of iran. in this paper, available approaches in the scope of determinants of ep are identified consist of contingency view, relational and resource based view. in this study, we examine relationship between resources, co...

Highlighting both the problems of composing and acquiring mineral rent, and the procedures and forms in which the rent is reflected in the price of mining products and energy resources are basic premises to emerge specific methodological elements of economic management of mineral resources. As our researches revealed, contractual duties represent one of these elements. Hence, the problem of new...

The global demand for strategic mineral resources has surged because of technological developments, with the associated resource security (SMRS) issues attracting significant research attention, especially in China. To fully understand this direction, 3722 studies were extracted from Web Science (WoS) and China's National Knowledge Infrastructure (CNKI). knowledge was mapped bibliographic recor...

diversification of phosphorus sources can bring substantial synergy effects within all thesustainable development domains: environmental, economic and social, and such an opportunity should not beoverlooked. urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their total material requirement (t...

Volatile elements and compounds found in extra-terrestrial environments are often the target of In Situ Resource Utilization (ISRU) studies. Although water hydroxide most commonly focus these studies as they can be used for propellant human consumption; we instead on possible exploitation sulfur how it could utilized to produce building materials Moon, Mars Asteroids. We describe physical chemi...

We tested this expectation by comparing the shell characteristics preferred by males and females in the shell-brooding cichl...

African rainforest harbors herbivores at high density. However, because plants and soils typically lack in some essential minerals, rainforest is not always a suitable habitat for herbivores. How they fulfill the mineral requirements is therefore an important question to animal ecology and conservation. Although large marshes, called 'bais', are often mentioned as efficient mineral-resource, li...
