|Development And Testing Of Real-Time Shovel-Based Mineral Sensing Systems For The Enhanced Recovery Of Mined Material
Andrew Bamber, Carol-Ann McDevitt, David Munoz-Paniagua, Matt Dirks, John LeRoss
The physical extraction of mineral resources for beneficiation is generally undertaken by stages including discovery, exploration, modelling, planning, design, development, operations and closure. In modelling, geological data is treated to define a contiguous orebody, which is then broken down into blocks based on grade.
|A newly developed XRF-Sensor with high sensitivity for increased sorting efficiency
Dr. GĂĽnter Buzanich
X-Ray Fluorescence spectroscopy (XRF) is an element sensitive detection method and all kinds of materials can be separated as long as they are different in at least one element with an atomic number of Calcium or higher. Due to this capability XRF-Sensors can amongst other things be used to separate different kinds of glass (lead-glass, ceramicsâ€¦), different metals (e.g. â€śmeatballsâ€ť in scrap preparation) or in mining plants to separate metal rich from dead rocks.

|Characterizing The Economic Value Of An Epithermal Au-Ag Ore With Laser Induced Breakdown Spectroscopy (Libs): Possibilities And Limitations
MSc. Marinus Dalm, Dr. MWN Buxton
LIBS was applied to 19 Au-Ag ore samples to investigate if this technique can be used to distinguish between economic and sub-economic ore either by direct detection of these elements or by using other elements as indicators.
|Integrating LIBS and NIR for detection of heavy metals in perlite ores
Dr. MWN Buxton, Adriana Guatame-Garcia
Perlite products are used as a filter aid in the food industry. For such applications, the purity of the material is one of the most significant parameters of control. Early detection of heavy metals is therefore of great industrial interest. In this study, a sensor-based approach for chemical and mineralogical characterization enabled the identification of patterns in the distribution of heavy metals in the perlite ore.
|Mutual Separation of Aluminum Alloys by Combining Appearance Recognition with Neural Network Analysis (ARENNA) and Laser-induced Breakdown Spectroscopy (LIBS) Sorters
Makoto Harita, Shuji Owada, Shigeki Koyanaka, Yoshifumi Kato, Mikio Kuzuya
In Japan, most scrap aluminum is recycled; however, the majority is recycled via cascade recycling, in which many kinds of aluminum alloys are mixed and used as casting alloys for manufacturing combustion engines. Although the demand for wrought aluminum has increased recently, the demand for casting alloys for combustion engines has gradually decreased.

Dr. Kai-Uwe Vieth, Matthias Richter, Prof. Dr.-Ing. Thomas LĂ¤ngle, Prof. Dr.-Ing. habil. JĂĽrgen Beyerer
Every bulk material sorting machine uses classification: objects are either discarded or accepted into one or more bins. In a classical system, both the features and the classifier are constructed by a vision engineer. While successful in the past, this approach is reach-ing its limits.
