This dataset describes the drying process of 1 kg of wet material in the production of metallurgical auxiliary materials, resulting in 0.99075 kg of dried product. This dataset should be used in conjunction with 1 kg of wet material. The data are collected from various metallurgical auxiliary material production processes. The dataset includes energy consumption and atmospheric emissions associated with the drying process, while infrastructure such as equipment manufacturing and facility construction is excluded from the system boundary.
