An additional problem in the flotation column was bubble coalescence and collapse of the froth. This was caused by the fatty acids, enhanced by the high dispersant concentration.
A novel method of quantifying coalescence using the change in gas holdup in the column was developed. A stable froth could be made at high fatty acid emulsifier concentration, but his promoted unselective flotation. Only by working at high percent solids (10% vs 1%) could sufficient emulsifier be introduced into solution without exceeding the dosage (per unit mass of solids) above which flotation is unselective. For such high percent solids work must be conducted at plant site. Preliminary plant column work was encouraging.
Extensive testwork on very fine feeds (80% $-$20 $ mu$m) at Niobec, and at Mt Isa Mines (Australia) confirmed that column flotation is ideal for selective flotation of fines principally due to reduced gangue entrainment.

Kumba Iron Ore’s Sishen mine is located in South Africa’s Northern Cape Province and produces about 40 million tons (Mt) of iron ore per annum. The ore body consists mainly of laminated and massive type hematite ore of which 30 Mt is being beneficiated by Dense Medium Separation (DMS), while the remaining 10 Mt is processed by the jig plant that was added as an expansion to the DMS processing route. The jigs at the jig plant are employed to treat coarse, medium and fine Run of Mine Ore (ROM). Due to the presence of finer particles on the screened ROM, hydrocyclones are employed on the secondary screen that feed the finer jig to produce fines on the overflow that is fed to the thickeners for dewatering by sedimentation, and the formation of clear liquid that can be recycled to the Jig plant. However, it was suspected that a substantial amount of the iron gets lost to the hydrocylone overflow with slimes. These slimes consist of very fine particles (about 90%-45μm) which make treatment with gravity concentration methods difficult. Sishen mine attempts to beneficiate the slimes using Pulsating High Gradient Magnetic Separators (PHGMS). However, PHGMS produce a concentrate consisting of 64.0% iron and 5.0% silica which render the slimes not suitable for pelletizing. Normally the slimes are considered as waste and are rejected to the slimes ponds. Rejecting slimes is not only a loss of resources, but it also poses severe long-term environmental problems. Recovery of iron minerals from the tailings produced in a large iron ore operation is of importance as it will result in environmental and economic benefits which indicate the importance of utilising those accumulated fines.

The city of Randfontein, in the Witwatersrand, hosts several slimes and tailings storage facilities which pose potential threat to the environment in the form of acid mine drainage (AMD). The latter, readily scavenges toxic metals, contaminating surrounding soils and water resources, thereby potentially compromising the overall environmental- and public health of the area. To this end, three slimes sections (section T001, T002 and T003) from the Gold One Millsite Slimes Complex were investigated, with the aim of understanding metal release from the slimes dam into the Randfontein area. To achieve this, the mineralogical and geochemical factors controlling metal release were investigated using combined core log analysis, cluster and discriminant analysis, x-ray diffraction analysis, bulk geochemical analysis, acid base accounting methods and selective sequential extraction procedures.

Диссертационную работу посвящено выявлению закономерностей процессов разделения шламовых вод с полидисперсной твердой фазой в осадительных центрифугах. В работе всесторонне исследовано влияние концентрации и дисперсного состава на прочность флокул к механическим воздействиям. Установлено, что остаточная скорость осаждения флокул после механического воздействия при постоянном расходе флокулянта имеет наибольшее значение при концентрации твердой фазы в шламе в интервале 7–30 г/дм3. Наилучшие результаты во всех опытах получены при концентрации твердой фазы, равной 10 г/дм3. Выявлено, что при концентрации до 7 г/дм3и свыше 30 г/дм3 наблюдается образование флокул, обладающих наименьшей остаточной скоростью после механических воздействий. С ростом содержания доли твердой фазы крупностью 40–100 мкм свыше 15 % возрастает прочность флокул, которые сохраняют свою форму и достаточно высокую скорость осаждения даже после механических воздействий. Разработаны рекомендации по выбору технологических параметров обезвоживания шламовых вод различных производств в осадительных шнековых центрифугах с использованием химического усиления флокулянтами агрегатообразования полидисперсных шламов. Полученные данные позволяют рекомендовать корректировку состава шлама перед вводом флокулянта как по концентрации, близкой к оптимальной, так и по содержанию доли класса крупностью 40–100 мкм свыше 15 %. Показано, что с ростом концентрации твердой фазы в сгущенном шламе свыше 140–150 г/дм3 существенно уменьшается прочность агрегатов к механическим воздействиям. Это позволяет рекомендовать сгущать шлам до заданной величины. Предложены пути минимизации механических воздействий на сфлокулированный шлам в центрифуге. В частности, предложен способ модернизации конструкции центрифуги, заключающийся в том, что вдоль боковой поверхности трубы питания выполнены каналы, направленные тангенциально к боковой поверхности трубы питания таким образом, чтобы направление течения суспензии из каналов совпадало с направлением вращения ротора. В результате такой подачи только малая часть потока испытывает сдвиговые напряжения. Другим направлением, снижающим механические воздействия на флокулы является установка в барабане разгонной втулки с направляющими трубками, препятствующими разбрызгиванию суспензии. В результате этих рекомендаций разработана усовершенствованная конструкция осадительной центрифуги, обладающая при соблюдении оптимальных условий флокуляции высокой степенью удаления твердой фазы, возможностью получения осадка относительно низкой влажности, а также низким расходам энергии на процесс.
The thesis is concerned with conformities to the law of processes of division of slime waters with a polydispersed hard phase in decanting centrifuges. The influence of concentration and dispersible composition on durability of floccules to mechanical influences was investigated in detail. The effect of the concentration and disperse composition on the flocculation strength to mechanical influence is investigated. It is found that the residual rate of floccules sedimentation after the mechanical influence at a constant rate of flocculant has a maximum value at a concentration of solids in the slime in the range of 7–30 g/dm3. The best results are obtained in all the experiments at a solids concentration of 10 g/dm3. It is found that at a concentration up to 7 g/dm3 and more than 30 g/dm3, the floccules are formed. They have the lowest residual rate after mechanical influences. With increasing content of the solid fraction of 40 – 100 microns over 15%, the strength of floccules increases. They retain their shape and relatively high sedimentation rate even after mechanical influence. The obtained data allow recommending correction of the slime composition before flocculant injection both the concentration close to the optimum, and the content of size fraction of 40 – 100 microns more than 15%. It was offered that with an increase in the degree of thickening of more than 140–150 g/dm3 the resistance of aggregates to mechanical influence substantially decreases.

The efficiency of desktop publishing is severely limited by the lack of sophisticated automatic document layout systems. State-of-the-art algorithms either require the input to be written in a description language such as HTML and LaTeX, or to be a manually designed layout template. However, description languages are ill-suited to express layout problems with weak semantics and layout templates shift the burden from the end user to the template designer. The first contribution of this thesis is an algorithm that solves a general class of layout problems by treating them as equitable resource allocation problems. The available document area is a resource that is distributed among inter-element gaps. The layout problem is transformed into a lexicographic min-ordering optimization problem that is solved using linear programming techniques in real-time. If the layout problem is over-constrained, the quality of the solution layout degrades gracefully. The layout algorithm finds the solution layout with the most equitable distribution of constraint errors among the soft layout constraints, i.e., the solution closest to the user''s original intent. Conversely, the layout algorithm detects the under-constrained subproblems that adversely affect the solution layout. It adds the minimal number of constraints required to achieve the fully specified layout problem that is closest to the user''s input. The second contribution is the creation of an intuitive direct manipulation user interface that lets users create the aforementioned class of general constrained layout problems. It hides the complexity of the constraint system and avoids the usability problems that have plagued constraint drawing applications. It eliminates the need of document description languages and manually-created layout templates. In the evaluation, we show that the best state-of-the-art specialized table layout algorithms do not outperform the general ICBM layout algorithm by any significant margin.
