Question

Quizplus · Accepted Answer

Mining for a low-grade ore requires large amounts of energy and resources to extract a small amount of usable material, leading to significant environmental damage. This is due to the need for extensive processing and waste removal to extract a sufficient amount of the mineral. Mining for a high-grade ore, on the other hand, is typically more efficient and requires less processing, resulting in a lower environmental impact. A moderate-grade ore falls in between the two and may vary depending on the specific mineral being extracted. A plentiful ore may also have a significant environmental impact, but this would depend on the location and method of extraction. A low- to moderate-grade ore also falls in between the two and may vary depending on the specific mineral being extracted.
