Can X-ray technology make mining more efficient?
In mining, the dual-energy method can be used to X-ray ore and determine its metal content. Fraunhofer EZRT is active in this area as well: a project with Chilean partners is underway to develop a process for measuring the copper content of mined rock. If the content is very low, the rocks are sortet out and not processed any further. This increases the efficiency of the processing and saves on water and energy, resources that are scarce in the mines located high in the Andes.
What benefit is there to X-raying food?
The method is truly universal, as can be shown by its application in the food industry. “Simple radiographic systems are already in use here, but for many problems, they don’t go far enough,” Ennen says. That’s why his team, in partnership with other companies, is building dual-energy X-ray systems that can detect bones in chicken fillets or fish and foreign objects in confectionery. The aim is to have bone-free fish on the table and make recalls of food containing dangerous foreign objects a thing of the past.
