Froth flotation is one of the most important mineral processing techniques. Over 90% of the nonferrous minerals and 50% of the ferrous minerals in the world are treated using flotation: a complicated technique including procedures from chemistry, physics and multi-scale fluid mechanics. The book introduces readers to air-forced and air-induced flotation cells and discusses the various mechanical structures and working principles involved. A number of examples from industrial engineering practice are also discussed throughout the book, helping readers to better understand the technology and relevant equipment. The book is intended for researchers, professionals and graduate students in the fields of mining and mineral processing engineering. 410 0$aSpringer Tracts in Mechanical Engineering,$x2195-9862 606 $aFlotation 615 0$aFlotation. 676 $a622.752 700 $aShen$b Zhengchang$0847321 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910484693103321 996 $aPrinciples and technologies of flotation machines$91892653 997 $aUNINA LEADER 03524nam 2200649zu 450 001 9910140105903321 005 20210807001110.0 010 $a2-940503-60-5 024 7 $a10.4000/books.iheid.1743 035 $a(CKB)2560000000352165 035 $a(SSID)ssj0001541325 035 $a(PQKBManifestationID)11879966 035 $a(PQKBTitleCode)TC0001541325 035 $a(PQKBWorkID)11534988 035 $a(PQKB)11519634 035 $a(WaSeSS)IndRDA00044195 035 $a(FrMaCLE)OB-iheid-1743 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/44543 035 $a(PPN)182833062 035 $a(oapen)doab44543 035 $a(EXLCZ)992560000000352165 100 $a20160829d2014 uy 101 0 $aeng 135 $aur||||||||||| 181 $ctxt 182 $cc 183 $acr 200 14$aThe Darfur refugees' plight : repatriation challenges for post-Doha Sudan 210 $cGraduate Institute Publications$d2014 210 31$a[Place of publication not identified]$cGraduate Institute Publications$d2014 215 $a1 online resource (130 pages) 225 0 $aeCahiers de l'Institut 300 $aBibliographic Level Mode of Issuance: Monograph 320 $aIncludes bibliographical references. 330 $aThe Darfur crisis has left behind a profound legacy of displacement, with some 300,000 refugees camped on the Chadian side of the border and about 2 million displaced internally within Darfur. Despite a reduction in armed hostilities and violent casualties since 2006, as well as a peace agreement signed at Doha in 2011, limited signs of voluntary repatriation are visible from eastern Chad; where refugees are seemingly willing, but not ready, to return. Further to the Doha peace settlement, they require genuine peace to be in place on the ground, marked by visible changes in the security landscape of Sudan. In particular, they ask for the prosecution of war criminals, disarmament of local militias, adequate compensation for human and physical losses, local reconstruction, and the departure of populations who have settled on their lands in the aftermath of mass atrocities. The marked demographic changes having taken place in Darfur over the past decade, and a ?peace? that fails to fully address impunity and be widely accepted, make the fulfillment of these requests seem far-fetched at present. While voluntary return is being discussed nationally and regionally, refugees underscore their profound need for justice and personal safety by remaining in the camps. When and how conditions for safe and dignified return will be met is something they are still carefully considering. 606 $aSocial Welfare & Social Work$2HILCC 606 $aSocial Sciences$2HILCC 606 $aSocial Welfare & Social Work - General$2HILCC 610 $amigration and refugees 610 $aprotection of civilians 610 $amigration policy 610 $aState | Nation 610 $ahuman rights 610 $aculture religion and identity 610 $acivil war 610 $ainternational refugee protection 610 $ahumanitarian action 610 $agovernance 615 7$aSocial Welfare & Social Work 615 7$aSocial Sciences 615 7$aSocial Welfare & Social Work - General 700 $aPraz$b Anna$0994136 801 0$bPQKB 906 $aBOOK 912 $a9910140105903321 996 $aThe Darfur refugees' plight : repatriation challenges for post-Doha Sudan$92276778 997 $aUNINA
