Processing of Low- Grade Uranium Ores

ores of lower grade than are usable at present Since the resources of these ores are at least ten times as great as those of ores from which uranium can be extracted at current costs, the processing of such low-grade ores is of particular interest to many countri Realizing the importance of this problem, the International Atomic.

LEACHING OF LOW-GRADE COPPER ORES: A CASE STUDY

the ore with the time of exploitation at the RTB mines [9] Oxide copper ore, mixed oxide-sulphide ores and low-grade copper sulphide ore, which, for economic reasons, cannot be enriched by flotation, may be processed by leaching methods Agents for leaching copper.

Ore

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
