Mineral Economics

Peak minerals: What can we learn from the history of mineral economics and the cases of gold and phosphorus?

Wellmer, F.W., Scholz, R.W.

Erschienen 2016 in Mineral Resources, December 2016, pp 1-21. Abstract: The objective of this paper is to provide a conceptual and empirical historic analysis of applications, misunderstandings, and fallacies surrounding the Hubbert curve, the U-shaped production curve of a commodity, and peak minerals. We show that the ultimate recoverable resources (URR) cannot be predicted by fitting a symmetric curve to the data of past (historic) production for any commodity on a global scale. Without knowledge of the URR, it is not possible to determine the peak production time. (...)

Efficiency performance of the world's leading corporations in phosphate rock mining

Bernhard Geissler, Michael C. Mew, Olaf Weber, Gerald Steiner

Erschienen in Resources, Conservation and Recycling, Volume 105, Part B, December 2015, pp. 246–258. Abstract: The prominence of phosphorus (P) is represented by three major aspects: first and most important, P is essential for all life on Earth; second, no other element or substance can act as a substitute for P; and third, P is considered a non-renewable resource and thus finite. In regard to global food security and P as one of the three major macronutrients, the world faces an extensive challenge to utilize this finite and unsubstitutable commodity in the most effective as well as the most efficient way. Efficiency in general has increasingly become of major importance over the last several decades, especially within competitive commodities. [...]

Efficiency developments in phosphate rock mining over the last three decades

Gerald Steiner, Bernhard Geissler, Ingrid Watson, Michael C. Mew

Erschienen in Resources, Conservation and Recycling, Volume 105, Part B, December 2015, Pages 235–245. Abstract: This paper appraises losses and efficiency in phosphorus mining processes. The distinction between resource and economic efficiency as crucial determinants of the mining decision process is outlined in relation to the kind of agents involved. Second, we apply a system and process approach to visualize and better deal with the complexity of the phosphorus supply chain and to provide a framework of the extended phosphorus supply chain for subsequent efficiency analyses.

Sustainable Phosphorus Management

Sustainable Phosphorus Management A Global Transdisciplinary Roadmap

Scholz, R.W., Roy, A.H., Brand, F.S., Hellums, D., Ulrich, A.E. (Eds.)

Erschienen 2014, Springer Verlag. Abstract: This book describes a pathway for sustainable phosphorus management via the Global Transdisciplinary Processes for Sustainable Phosphorus Management project (Global TraPs). Global TraPs is a multi-stakeholder forum in which scientists from a variety of disciplines join with key actors in practice to jointly identify critical questions and to articulate what new knowledge, technologies and policy processes are needed to ensure that future phosphorus use is sustainable, improves food security and environmental quality and provides benefits for the poor. The book offers insight into economic scarcity and identifies options to improve efficiency and reduce environmental impacts of anthropogenic phosphorus flows at all stages of the supply and use chain.
