Facets:
value: under roasting conditions
type: TEMPORAL
Source sentences:
text: The chemical reactivity of the new lithium-containing mineral which is produced pursuant to our invention is clearly evidenced by the fact that although beta-spodumene will react with concentrated sulfuric acid only under roasting conditions, the new mineral will readily react with very dilute (10% or less) sulfuric acid either in the cold or when heated.
