Metalliferous mining activities produce a large quantity of waste materials (such as tailings), which frequently contain excessive concentrations of heavy metals. These mining activities and waste materials have created heavy metal pollution problems through wind and water erosion. An integrated vetiver technique (IVT) for remediation of heavy metal contamination raised from mining activities i...

Having a comprehensive evaluation model with reliable data is useful to improve performance of supply chain. In this paper, according to the nature of supply chain, a model is presented that able to evaluate the performance of the supply chain by a network data envelopment analysis model and by using the financial, intellectual capital (knowledge base), collaboration and responsiveness factors ...

Europe’s almost total dependence on foreign suppliers of metals impacts negatively the continent’s balance trade, opens region to potentially damaging supply problems, allows actors place political demands European leaders and economies, has a considerable negative environmental impact in many parts world. Europe sound economic reasons, moral responsibility, promote more mining continent where ...

Supply chain management is a set of used methods for the efficient integration of suppliers, manufacturers, warehouses, and sellers to response customer requirements to reduce system costs and to distribute products at the right place and right time. This study aims to identify and rank the supply chain damages using the analytic network process as a practical case in a fast moving consumer goo...

Natural disasters and unexpected disruptive events have forced practitioners researchers to build resilience capability into their systems survive grow in tempestuous turbulent times. This study empirically examined the effect of multi-dimensional supply chain flexibility (MDSCF) improving (SCRES) under a high (SC) risk environment. The incorporated survey technique utilized valid responses fro...

The platinum group of metals (PGMs) possess a range of unique chemical and physical properties and are increasingly finding important uses in a wide variety of environmentally-related technologies (eg. catalytic converters, fuel cells, electronics). The typical ore grade for PGM mineralisation is similar to gold (g/t) but the processing is more akin to base metals (at percent). The typical sche...
