As a result, automated procedures to control and measure process efficiency have become popular: The demand for sustainable mining and metals processing is globally increasing. Mineral Liberation Analysis is a well established technique to analyse and optimize mining processes and its significance to process mineralogy studies and mineral & metallurgical processing has been widely reported. Dedicated systems consisting of an optimized scanning electron microscopes (SEM) and usually several X-ray detectors are an established solution. With the advent of large area SDDs (Silicon drift detector) and progress in stage automation on conventional SEMs, the speed of X-Ray acquisition is no longer a limiting factor. However, until now, the particle analysis packages on commercially available systems do not lend themselves to Mineral Liberation Analysis without significant modification. INCAMineral is a new solution for mineral liberation analysis which runs on conventional SEMs equipped with large area SDDs.展开更多

Around this theme,Marx went beyond the perspective of religious criticism and gave priority to the analysis of the modern political state in the field of civil society,lightening the limits of political liberation and the path of human liberation.展开更多

As this is a tomographic technique performed with an XRM, it is non-destructive and does not require complex preparation of polished sections typical of SEM-EDS techniques (such as MLA and QEMSCAN). It complements these existing techniques by providing 3D information and mineral liberation of multi-phase particles with much larger sample volume statistics but at a fraction of the time. In several applications, the technique is superior. These include the characterization of tailing loss in precious minerals; the characterization of porosity, particle size distribution, crack and pore network analysis during comminution, heap leaching and for texture and exposure/lock class analysis for floatation.展开更多

Medical Journal of Chinese People’s Liberation Army (Med J Chin PLA) is a multiple-subjects medical periodical published by the People’s Military Medical Press, under the auspice of Department of Health, General Logistics Department of PLA, and it is issued domestically and abroad. Med J Chin PLA has become one of the source journals of statistics in Chinese Scientific Thesis and Chinese Scientific Quotation Database, the key periodical of multiple-subject medical journals, and is a prize journal of National Periodical Award and one of the Top Hundred Periodicals in China. Med J Chin PLA is issued monthly. Its permanent sections include Expert Forum, Research on Special Topics, Medical Treatises, Experimental Research, Clinical Research, Technology and Methodology, Discussion of Knotty Cases (Pathology), Reviews, Military Medical Sciences, News in Medicine etc. Manuscripts sent by both domestic and overseas writers are welcome. Contribution of reviews is usually invited by the Editors, but recommendations for topics and authors are welcomed.展开更多
