About this site

Molybdenum and copper-molybdenum porphyries are mined by open-pit or by underground methods. Once the ore has been crushed and ground, the metallic minerals are then separated from gangue minerals (or the molybdenum and copper from each other) by flotation processes, using a wide variety of reagents.

Molybdenum Processing - IMOA

Ball or rod mills crush and grind the mined ore to fine particles that may be only microns (10-3 mm) in diameter, releasing molybdenite from the gangue (worthless rock). The grinding mills on the right reduce rocks the size of soccer balls to the size of gravel. Further ball milling

Extraction of Resources Geology

The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body. This leads to a mathematical resource estimation to ...

About this site

The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore. The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals. After the minerals are processed, the waste rock and mine tailings are stored in large, above-ground piles and containment areas. These waste piles, along with the ...
