摘要:Abstract(#br)The SnO 2 68 Ge/ 68 Ga generator system is widely used in medical imaging to provide a regular supply of the radionuclide 68 Ga (T ½ = 68.3 min) for positron emission tomography (PET). These generators are also used to supply 68 Ga for the fabrication of tracer ...

摘要:Abstract(#br)In line with the principles of cleaner production, the removal of monazite via reverse flotation was investigated with a view to reducing the radioactivity of a heavy mineral sands waste stream. Another benefit was to create a potential REE by-product from the Namakw...

摘要:Abstract(#br)The long-term generation of acid rock drainage (ARD) from sulfide-bearing mine waste is a major environmental liability for the mining sector. Previous studies have demonstrated that these ARD risks can be effectively avoided, and resource recovery simultaneously imp...

摘要:Abstract(#br)Effective management of the risks associated with acid rock drainage (ARD) requires the ability to identify material with a potential to generate ARD reliably. With the increasing prevalence of quantitative mineralogy (Quantitative XRD, auto-SEM), opportunity exists ...

摘要:Abstract(#br)The ultra-fine milled tailings generated during the processing of PGM ores in South Africa have a theoretical potential to sequester significant amounts of CO 2 (∼14 Mt per annum) through mineral carbonation. Mg-bearing orthopyroxene is the major sequestrable mi...

摘要:Abstract(#br)With the installation of ultrafine grinding on many platinum operations in southern Africa, there were concerns as to whether this would cause rheologically complex behaviour during the subsequent flotation of the ore. Rheologically complex behaviour refers to the no...

摘要:Abstract(#br)Increasing atmospheric CO 2 concentration is currently of considerable concern in terms of global warming. A possible technology that can contribute to the reduction of CO 2 emissions is its sequestration by mineral carbonation. In this study, tailings from several d...

摘要:Abstract(#br)A method to describe froth stability in industrial flotation cells, and its link with froth recovery, is discussed in this paper. The direct measurement of froth stability in industrial flotation cells is still controversial, and different techniques have been develo...

摘要:Abstract(#br)A methodology for characterising shear rate profiles in tumbling mills based on in situ trajectory fields from Positron Emission Particle Tracking (PEPT) experiments is presented. Experiments were carried out in a laboratory scale mill fitted with lifter bars, pulp l...

摘要:Abstract(#br)Concentrators processing PGM bearing ores make use of polysaccharide depressants to reduce the recovery of the undesired naturally floatable gangue minerals, mainly silicates, present in the ore. Recent work has shown that high depressant dosages can completely depre...
