Chalcopyrite (CuFeS2) is the most important copper ore because it is the most abundant one. It is a yellow-greenish mineral that forms in hydrothermal deposits. The method of analysis of chalcopyrite used by one of the many mineral analysis laboratories involves digestion of the minerals that is to say, dissolution of the mineral and separation of the element and compounds that form it. This lab uses a traditional method of digesting chalcopyrite, which leads to lower percentages of extraction and higher digestion times, which is why an alternative digestion method, microwave digestion, is proposed in order to increase the percentage of extraction and lower digestion times. In order to achieve that goal, a bibliographical revision of available literature that compares the percent of extraction and/or the digestion times of traditional and microwave digestion was done. 1675 papers were found and after applying several filters to them, 9 articles were left. Thee 9 articles were summed up in 2 tables and explained. Moreover, 10 microwave digestors were compared and 1 of those was proposed to be used based on its cost per unit of sample and technical specifications. Microwave digestion is as much 5 times more effective than traditional digestion in terms of percentage of extraction and 96% more efficient than traditional digestion in terms of minutes of digestion. The digestor model MSLEX08 is proposed to be used to digest chalcopyrite in this lab.
