Upgrading Ores
Legal definition for Indian law research
Definition
Upgrading ores, means as the high-grade deposits become more inaccessible or exhausted and as shipping costs increased, it became necessary to separate and discard unusable materials from the iron ores at, or near, the mines. Processes broadly termed as beneficiation were developed to upgrade the ore before shipment, Encyclopaedia Britannica, Vol. 21, 15th Edn., pp. 360-61.
