Improving the recovery of coarse coal particles in a Jameson cell

It has been observed in several Jameson cell installation where the source for flotation feed is deslime screens, that the recovery of coal particles greater than 0.5 mm is not as great as that of finer material. Consequently, a research project was undertaken at a CHPP in the Bowen Basin Queensland to assess the possibility of increasing the recovery of coarser particles (+0.5 mm) within the downcomer of the Jameson cell. The effect of decreasing turbulence and agitation in a commercial-scale downcomer was investigated to assess the effect oil the recovery of both coarse and fine coal particles. This paper details the findings of the test work, summarising the results relating to differences in the operating parameters within the downcomer. (C) 2005 Elsevier Ltd. All rights reserved.

Applications of the Jameson cell at the head of base metal flotation circuits

The Jameson Cell is a high intensity flotation device, which utilises induced air from the atmosphere. It was developed jointly by Mount Isa Mines and Professor Graeme Jameson of the University of Newcastle in the 1980s. It is proven to generate fine bubbles, in the order of 300 to 500 µm, in a high intensity, high shear and compact zone contained in the downcomer. This aerated mixture exits the downcomer into the pulp zone, which is the quiescent mineral and gangue separation zone. A number of Australian base metal flotation circuits feature a reverse flotation stage at the head of the circuit. Testwork and plant operating data has shown that the use of a Jameson Cell in the prefloat cleaner application has further improved prefloat gangue recovery and selectivity. Operation of a Jameson Cell in a carbonaceous/pyrite prefloat cleaner duty at the Mt Isa copper concentrator increased copper recovery and reduced pyrite in the copper concentrate. Testwork at Zinifex Century Zinc Mine showed a decrease in zinc losses by the utilisation of Jameson Cell prefloat cleaner. Appraisal of a Jameson Cell in a scalping role within the Mt Isa Copper Concentrator indicated significant benefits could be achieved.

Playing with picturebooks : postmodernism and the postmodernesque

This thesis traces the influence of postmodernism on picturebooks. Through a review of current scholarship on both postmodernism and postmodern literature it examines the multiple ways in which picturebooks have responded to the influence of postmodernism. The thesis is predominantly located in the field of Cultural and Literary Studies, which informs the ways in which children’s literature is positioned within contemporary culture and how it responds to the influences which shape its production and reception. Cultural and Literary Studies also offers a useful theoretical frame for analysing issues of textuality, ideology, and originality, as well as social and political comment in the focus texts. The thesis utilises the theoretical contributions by, in particular, Linda Hutcheon, Brian McHale, and Fredric Jameson as well as reference to children’s literature studies. This thesis makes a significant contribution to the development of an understanding of the place of the postmodern picturebook within the cultural context of postmodernism. It adds to the field of children’s literature research through an awareness of the (continuing) evolution of the postmodern picturebook particularly as the current scholarship on the postmodernism picturebook does not engage with the changing form and significance of the postmodern picturebook to the same extent as this thesis. This study is significant from a methodological perspective as it draws on a wide range of theoretical perspectives across literary studies, visual semiotics, philosophy, cultural studies, and history to develop a tripartite methodological framework that utilises the methods of postclassical narratology, semiotics, and metafictive strategies to carry out the textual analysis of the focus texts. The three analysis chapters examine twenty-two picturebooks in detail with respect to the ways in which the conventions of narrative are subverted and how dominant discourses are interrogated. Chapter 4: Subverting Narrative Processes includes analysis of narrative point of view, modes of representation, and characters and the problems of identity and subjectivity. Chapter 5: Challenging Truth, History, and Unity examines questions of ontology, the difficulties of representing history, and addresses issues of difference and ‘otherness’. The final textual analysis chapter, Chapter 6: Engaging with Postmodernity, critiques texts which engage with issues of globalisation, mass media, and consumerism. Brief discussion of a further fifteen picturebooks throughout the thesis provides additional support. Children’s texts have a tradition of being both resistant and compliant. Its resistance has made a space for the development of the postmodern picturebook; its compliance is evident in its tendency to take a route around a truly radical or iconoclastic position. This thesis posits that children’s postmodern picturebooks adopt what suits their form and purposes by drawing from and reflecting on some influences of postmodernism while disregarding those that seem irrelevant to its direction. Furthermore, the thesis identifies a shift in the focus of a number of postmodern picturebooks produced since the turn of the twenty-first century. This trend has seen a shift from texts which interrogate discourses of liberal humanism to those that engage with aspects of postmodernity. These texts, postmodernesque picturebooks, offer contradictory perspectives on aspects of society emanating from the rise in global trends mentioned above.
