In the development and utilization of copper resources, the grading operation of the copper ore beneficiation plant is also an important production link in the separation of copper ore. As the difficulty of copper mining and sorting …

In this bulletin the subject of ore dressing is approached from the economic rather than from the technological standpoint, and the supporting data have been compiled with a view to their bearing upon the economic exploitation of ore deposits. Results obtained are stressed rather than the details of processes and the physics and chemistry involved. For discussions …

from Michigan ores. Like iron mining, the extraction of copper has increasingly become an open pit enterprise. A peculiarity of the industry is that most copper mines yield small amounts of other nonferrous metals—especially gold and silver—as byproducts. The process of bringing metallic copper to market usually in-volves four distinct ...
