Other fixed costs were considered to be miscellaneous expenses, and accounted for 0.1 of total fixed cost. The operating cost of refining was calculated using the factor 15 USD/lb refined REE Schuler, 2011. From this average operating cost of refining per ton ore was determined as follows, where D is defined as above:

Copper Mining and Processing: Everything you Need to Know

The laborious task of mining copper ore by hand made it difficult to obtain large quantities for production. During the Industrial Revolution, coal and steam powered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week.

Partpetitiveness

Ore Grade The costs of mining and processing copper are more closely related to the gross tonnage of the ore than tonnage of copper in the ore.5 A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore. However, because the rich ore con tains more copper, it requires less of these inputs
