Dump, Heap, and in Situ Leaching: Legal Constraints

Douglas K. Miller, Proceedings of 27th Annual Rocky Mountain Mineral Law Institute (1981)

Hydrometallurgical processes such as dump, heap, and in situ leaching are important because they make possible the extraction of much needed mineral resources from low grade ores, small deposits and wastes. This paper will discuss these techniques with reference to the recovery of copper, gold, and uranium. The purpose of the paper will be to identify some of the major legal constraints on new operations with particular emphasis on constraints imposed by federal law.1
