3. Longitudinal characterization of Dunkirk production
We carried out an index I assessment campaign defined by Directive 2013/59/Euratom on slags produced by the Dunkirk plant over 6 months, from January to June 2015.
3.1 Sampling
The ores consumed by Dunkirk are homogenized; ship cargoes are unloaded in superimposed layers to form stockpiles, which are then taken back by slice to feed the three blast furnaces in the smelting department.
A stockpile represents a week's consumption. At the blast furnace, slag is taken at each pour. We collected slag samples from HF4, the plant's largest, between 1 er June and December 31, 2015. From each sample, a constant mass was taken after grinding. These constant mass samples were pooled to obtain a compound...
