fingerprint dive into the research topics of towards circular economy in mining: opportunities and bottlenecks for tailings valorization. together they form a unique fingerprint. circular economy earth & environmental sciencesmay 18, 2021 while these technologies will open up new ways for mining companies to optimize the valorization of existing resources or allow access to new ones, they are unchartered territory in terms of business models, processes, and potential social and environmental externalities. To spread the risk of new capital-intensive projects, these financing valorization of a mining effluent by selective recovery of Zn using solvent extraction marta avila, gustavo perez and manuel valiente universitat autonoma de barcelona, spain abstract. Zn is a typical metal component of acidic mining waters. its selective recovery is a goal to valorizetailings have the potential to be transformed from hazardous waste to potentially valuable secondary metal sources. the valorization of mining waste could add to the raw materials supply, and subsequently reduce the environmental impact. circular economy concepts can help to create value from mining

In a statement tuesday, alamos said its netherlands-based office would file an investment treaty claim against hanced) landfill mining. these fractions typically present challenging characteristics for processing and valorization methods and, hence, they have been largely discard-ed in previous landfill mining projects. this situation has hindered the economic and environmental feasibility of landfill mining, since most of the excavated waste has
sep 18, 2017 On oct. 17, 2008, a-cap resources ltd released the result of a scoping study conducted by srk consulting. the preferred project option comprises the mining of million tonnes of ore containing million lbs 6,923rooted in an ecologically destructive sectoral economy, post-mining territories bear the scars of unsustainable development, the effects of which have yet to be dealt with. As territories that are often heritagized and that have been both visibly and invisibly weakened, they offer contemporary settings where experimentation for the transition to a post-carbon society is particularly relevant.may 21, 2021 enhanced landfill mining is also relevant for municipal solid waste. In this case landfill mining separates waste into directly recyclable materials and a refuse-derived fuel fraction, which is further converted into high-added-value products. using the new plasma gasification technology, it is possible to practices and technologies for waste valorization from landfills and minea workshop on technologies in the landfill-mining sector, which resulted in an overview on landfill mining projects and on state-of-the-art as well as enhanced recovery technologies
