A study of recovery and separation of heavy metal ions from waste solutions using precipitate flotation
- Authors: Ren, Xiang (Sean)
- Date: 1999
- Type: Text , Thesis , PhD
- Full Text: false
- Description: An important industrial problem is the production of wastewater containing a large amount of heavy metal ions. The study described in this thesis is trying to use precipitate flotation technology to explore techniques for not only removing heavy metal ions from the solution, but also selectively separating them to recycle of the recoyered metal value from industry wastewater. Zinc and copper hydroxide precipitation and flotation behaviour have been studied. lt shows that it is almost impossible to separate copper and zinc ion using hydroxide precipitate flotation when the solution contains Fe3+ or Al3+ ions. The influence of additional ions such as Ca2+ and Mg2+, and other electrolytes on the flotation and separation have been studied. DLVO theory has been used to explain the mechanisms occurring in the process. A new process, named "self-carrier" precipitate flotation us~g anionic surfactants, has been developed to improve the flotation recovery and reduce the consumption of collector. The mechanism of the process is discussed in detail with reference to data collected from Optical Microscopy, Scanning Electron Microscopy and Zeta Potential Measurement. The xanthates are the most commonly used class of sulphide mineral collectors. This study investigated the copper sulphide precipitate reactions and the aggregation behaviour, the influence of oxidation, additional ions etc., and successfully used xanthate to float the sulphide precipitates. The mechanisms occurring in this process have been discussed. The investigation of the sulphide precipitate flotation behavior using a cationic collector has also been carried out to discover the possibility of copper and zinc separation. An important application of this study is the flotation and separation of copper and zinc ions from industry wastewater. The tailing wastewater from a mineral processing plant, Woodlawn Mines (N.S.W., Australia), which contains high concentrations of harmful heavy metal ions was used to test the flotation and separation of the heavy metal ions. Both xanthate and cationic collectors have been investigated for the flotation separation. Effective separation has been achieved .

Copper loss into rotary holding furnace slag
- Authors: Burrows, Alistair
- Date: 1999
- Type: Text , Thesis , Masters
- Full Text: false
- Description: The Rotary Holding Furnace (RHF) is used in combination with the Copper Isasmelt Furnace as a settling vessel. This study investigated the phenomenon of entrained copper losses into RHF slag. Research work was conducted by laboratory-scale flow modelling, and by plant sampling of the RHF at Mount Isa Mines Limited. Laboratory fold modelling was conducted to measure the residence time distribution of a simulated slag layer in a l;'0 -scale model of the RHF. A novel technique, involving a copper tracer dissolved in an organic solvent extractant solution, was used for these experiments. Plant trials complemented the laboratory work with a variety of slag sampling campaigns. Residence time tests were also attempted on the RHF slag. In combination, the laboratory and plant scale experimental work performed in this investigation helped to highlight some likely causes of entrained copper loss in the RHF. Laboratory cold modelling of the RHF suggests that the depth of the upper liquid layer is • likely to affect the fluid flow patterns, and therefore the residence time distribution expected of the layer. A stratification of the flow was prevalent in thick upper liquid layers, but absent when thin upper layers were used. A stagnant region within the upper layer0 0f the model was identified. The introduction of gas injection through porous plugs caused mixing within the upper liquid layer. Stable waves were produced at the liquid liquid interfate. ' .. Plant experiments were constrained by commercial operating schedules. Several parameters were investigated during two different periods of experimental work. Granulated slag sampling indicated a link between the duration of continuous slag discharge and the copper content of the slag. Evidence was found that suggests the presence of interfacial waves.

Developing a spiritual health and life-orientation measure for secondary school students

- Description: The problem posed in this project was the development of an instrument to give a balanced assessment of young people’s spiritual health. Spiritual health is a dynamic state of being, which can be reflected in how well people relate in up to four domains of human existence, namely with themselves; with others; with the environment; and/or with a Transcendent Other. A convenience sample of 850 secondary students in State, Catholic, Christian Community and other independent schools in Ballarat and western suburbs of Melbourne were surveyed during 1999 to determine how important they considered each of the four sets of relationships to be for an ideal state of spiritual health (called Life-Orientation). They also expressed how each area reflected their personal experience most of the time (called Spiritual Health). Extensive factor analysis enabled the original 60-item instrument to be reduced to a reliable, compact 25-item Spiritual Health And Life-Orientation Measure (SHALOM for short). Analysis of variance and t-tests revealed significant variations between students’ views when compared by school type, gender, and year level. SHALOM has advantages over previous instruments in that it is balanced across the four domains of spiritual well-being, is more sensitive, and it compares people’s stated ideal position, with their lived experience, not others’, in determining the quality of relationships which constitute their spiritual well-being.

- Description: Changzhou City, underlain by a multi-layered aquifer system in Quaternary sediments in the Great Yangtze River Delta region, experienced a maximum land subsidence rate of 147 mm/year in the early 1980s due to excessive groundwater extraction. A large-scale monitoring station of 11 borehole extensometerswas established in the city in 1983 to investigate land subsidence. Nine stratawere predetermined in the Quaternary depth interval andmonitored by borehole extensometers. Presented in this paper are the long-term observations of land subsidence, strata compression and groundwater level in four aquifers from 1984 to 2002, and discussion on strata compression based on the measured data with reference to the stratigraphy, soil properties, groundwater withdrawn and literature of similar situations. The compression of strata varies significantly and is strongly influenced by groundwater drawdown in the second confined aquifer, or CA2. The groundwater level in CA2 declined from −55 m in 1981 to −76 m in 1994 and the land subsidence rate remained high. After the city government enforced restrictions on groundwater extraction in 1995, the extraction rate sharply reduced, the groundwater level in CA2 steadily recovered to −56 m until 2003, and the land subsidence rate declined to 10 mm/year in 2002. From 1984 to 2002, the land subsidence was mainly attributed to the consolidation of the thick aquitard overlying CA2. In the future, to prevent the subsidence rate from rising, it is vital to stop groundwater drawdown in aquifers.
