When the Kaunis Iron Mine opened in Sweden, it was the newest in one of Sweden's biggest industries. The mine contracted with Degerfors Laboratory (D-LAB) for their iron analysis. Before analysis could be run on the samples, however, the ore had to be dried and moisture levels measured.
D-LAB had a problem: their current moisture determination methods used a manual balance that could only handle one sample at a time, requiring a technician's attention every five minutes. The ISO 3087:2020 method used was also a problem, as a single run could take more than 5 hours to complete. The lab turned to LECO for a solution.
