Molybdenum Processing

Molybdenum Processing

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 reduces the material to the consistency of face powder.

Ore grinding – this uses a single stage SAG mill operating in a closed circuit. This produces a 200 micron feed, which is then directed to the leach tanks. The SAG mill operation is unusual in that sulphuric acid is added to the circuit to start the leach process early in advance of the leach tanks.

Lead Processing

Various fluxing materials, such as limestone or iron ore, are mixed with the ore concentrate. The mix is spread on a moving grate, and air is blown through at a temperature of 1,400 °C (2,550 °F). The sulfur, along with coke additions, serves as a fuel and is combusted to sulfur dioxide gas, which is usually recovered for the production of sulfuric acid as a by-product.
