technologyComment of fluorspar production, 97% purity (GLO): Open cast mining of resource. Separation by crushing, grinding and flotation. technologyComment of scandium oxide production, from rare earth tailings (CN-NM): See general comment.
technologyComment of boric acid production, anhydrous, powder (RER, RoW): This dataset models the production of boric acid from colemanite minerals (calcium borates) with the aid of sulfuric acid, with process yield of 95%. As by-product, gypsum (CaSO4) is produced. The production of boric acid can be summarized with the following reaction equation: (2CaO.3B2O3.5H2O) + 2 H2SO4 → 3 (B2O3.3H2O) + 2 CaSO4
technologyComment of potash salt production (RER): This datasets corresponds to the technology used in Europe for potash mining.
technologyComment of stone meal production (CH, RoW): Values refer to a commonly used technology for this product.
technologyComment of dolomite production (RER): This datasets corresponds to the technology used in Europe for limestone mining. Crushing and milling assumed as a first approximation. An overall yield of 95% is assumed.
technologyComment of phosphate rock beneficiation (RER): This datasets corresponds to the technology used in Europe for phosphate rock mining and beneficiation.
