Quizplus · Accepted Answer

The lack of new earth-moving equipment and mining techniques is not a limiting factor for mining lower-grade ores because advancements are constantly being made in mining technology and equipment. Factors that do limit the mining of lower-grade ores include increased cost of mining and processing larger volumes of ore, increasing shortage of freshwater, environmental impact of increased land disruption, and pollution produced during mining and processing activities.
