So the use of secondary raw materials gains is important due to economic and ecological reasons. Non Ferrous-, precious- and rare earth metals were detected in household waste (Municipal solid waste, MSW) for years. In MSW-treatments plants NF-metals are actually mostly separated from dried fractions. The separation of these metals is carried out with the aim of removing particles which disrupt further processing. A selective enrichment of individual non-ferrous metals has not been carried out previously. The separated fractions contain mixtures of Al, Cu, Zn, Pb, Sn, alloys, precious metals (e. g. Au, Ag, Pt) and rare metals (Ga, In, Nd etc.) along with considerable amounts of contaminations. The R\&D project "NE-Rec" selectively processes the coarsely separated non-ferrous-metal-conglomerates increasing the concentration of targeted metals. Metals and metal mixtures are concentrated by sorting steps and the impurities are discharged from the process. Still contaminated precious metals are then subjected to a wet-chemical treatment. So metals can be specifically brought into solution or can be precipitated to separate unwanted components (inerts, polymers, foreign metals). Further the relevant metals will be concentrated by thermal-metallurgical processes. The technology, developed in the R\&D project, enables identification, separation and processing of non-ferrous metals, precious metals and REM in household waste and transfers them into further processable individual fractions.}, language = {en} } @inproceedings{NarraBrinkerAy, author = {Narra, Satyanarayana and Brinker, Mona and Ay, Peter}, title = {Particle size distribution of communited and liberated cereal straws measured with different image analysis systems and their characteristic influence on mechanical pellets quality}, series = {XXVI International Mineral Processing Congress - IMPC 2012 : New Delhi, India, September 24 - 28, 2012}, booktitle = {XXVI International Mineral Processing Congress - IMPC 2012 : New Delhi, India, September 24 - 28, 2012}, publisher = {New Delhi}, isbn = {81-901714-3-7}, language = {en} } @inproceedings{NarraDasguptaAyetal., author = {Narra, Satyanarayana and Dasgupta, Sunanda and Ay, Peter and Zeng, T. and Weller, N.}, title = {Pelletisation of Rye- and Wheat straw with additives}, series = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, booktitle = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, publisher = {ETA-Florence Renewable Energies}, address = {Florence}, isbn = {978-88-89407-55-7}, language = {en} } @inproceedings{NarraGlaserAy, author = {Narra, Satyanarayana and Glaser, Claudia and Ay, Peter}, title = {Abrasion and strength of biomass pellets as main mechanical stability characteristics}, series = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, booktitle = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, publisher = {ETA-Florence Renewable Energies}, address = {Florence}, isbn = {978-88-89407-55-7}, language = {en} } @inproceedings{KarthikeyanAyNarra, author = {Karthikeyan, J. and Ay, Peter and Narra, Satyanarayana}, title = {Energy Production from Agricultural residues and Crop processing Wastes: Some Problems and Perspectives}, series = {International Conference on Green Power Generation: Vision 2020}, booktitle = {International Conference on Green Power Generation: Vision 2020}, doi = {10.13140/2.1.3330.8965}, pages = {9}, language = {en} } @inproceedings{NarraGlaserGusoviusetal., author = {Narra, Satyanarayana and Glaser, Claudia and Gusovius, Hans-J{\"o}rg and Ay, Peter}, title = {Comparison of grinding and liberation processes for stalky biomass materials as a prerequisite for production of energy pellets with high calorific value}, series = {XXV International Mineral Processing Congress, IMPC 2010, "Smarter processing for the future", Brisbane, Australia 6-10 September 2010, congress proceedings}, booktitle = {XXV International Mineral Processing Congress, IMPC 2010, "Smarter processing for the future", Brisbane, Australia 6-10 September 2010, congress proceedings}, publisher = {AusIMM}, address = {Carlton South, Australia}, isbn = {978-1-921522-28-4}, language = {en} }
