Industrial scale production of zinc powder using alkaline leaching–electrowinning processes. .This book provides a comprehensive description of alkaline hydrometallurgy of amphoteric metal hazardous wastes. Topics focus on leaching of zinc and lead hazardous wastes, purification of leach solution of zinc and lead, electrowinning of zinc and lead from purified alkaline solutions, chemical reactions taking place in the production flowsheets, thermodynamic and spent electrolyte regeneration, alkaline hydrometallurgy of low-grade smithsonite ores, recovery of molybdenum and tungsten using ion flotation and solvent extraction processes and their application in chemical synthesis of Nb and Ta inorganic compounds, and industrial scale production of 1500-2000 t/a zinc powder using alkaline leaching–electrowinning processes. Processes described are cost-effective, generate lesser secondary pollutants, and have been applied widely in China. Readers that will find the book appealing include solid waste engineers, environmental managers, technicians, recycling coordinators, government officials, undergraduates and graduate students, and researchers. .Handbook of Environmental Engineering,2512-1359 ;18Waste managementEnvironmental sciencesPollution preventionWaste Management/Waste Technologyhttps://scigraph.springernature.com/ontologies/product-market-codes/U31001Environmental Science and Engineeringhttps://scigraph.springernature.com/ontologies/product-market-codes/G37000Industrial Pollution Preventionhttps://scigraph.springernature.com/ontologies/product-market-codes/U35020Waste management.Environmental sciences.Pollution prevention.Waste Management/Waste Technology.Environmental Science and Engineering.Industrial Pollution Prevention.363.728628.4Youcai Zhaoauthttp://id.loc.gov/vocabulary/relators/aut868461Chenglong Zhangauthttp://id.loc.gov/vocabulary/relators/autBOOK9910254315703321Pollution Control and Resource Reuse for Alkaline Hydrometallurgy of Amphoteric Metal Hazardous Wastes2088771UNINA04165nam 2200589 a 450 991097358450332120251117005433.09966-792-07-4(CKB)2670000000033887(EBL)3001541(SSID)ssj0000431922(PQKBManifestationID)11264490(PQKBTitleCode)TC0000431922(PQKBWorkID)10476792(PQKB)10876784(MiAaPQ)EBC3001541(Au-PeEL)EBL3001541(CaPaEBR)ebr10394799(OCoLC)923563068(BIP)35277681(BIP)23570773(EXLCZ)99267000000003388720080819d2008 uy 0engur|n|---|||||txtccrDecentralization and devolution in Kenya new approaches /edited by Thomas N.

Management and Utilization of Constituency Development Funds in Kenya""; ""Index""; ""Back Cover""Efficient delivery of public services in Africa and other developing regions has for a long time been hindered by highly centralized government bureaucracies (Mwabu et al., 2001). In Kenya, several efforts have been made to reduce unnecessary layers of government to make service provision to the populace more effective. This book reports on recent decentralization and devolution innovations in Kenya. The volume is organized into three parts and contains a total of 12 chapters including the introduction. The chapters in Part 1 (Structures and Institutions) provide a comprehensive analysis of institutional and organizational environment in which decentralization and devolution reforms have been taking place over the last three decades. Part 2 (Principles and Processes) contains chapters that clarify decentralization and devolution concepts, with applications to selected local authorities. The chapters in Part 3 (Service Delivery and Financing) illustrate advantages of provision and financing of services at the local level, with a focus on the role of community participation in improving accountability and efficiency in resource use.Decentralization in governmentKenyaLocal governmentKenyaDecentralization in governmentLocal governmentKibua T.
