Molybdenum Ore Processing by Flotation

05/05/2016  Molybdenum Ore Processing by Flotation How to separate copper molybdenum; the problem. Molybdenum is found in small amounts in practically all low grade porphoritic copper ores. It is usually present as the sulphide, molybdenite, which is readily recovered in the copper flotation concentrate. Copper sulphide flotation concentrates may contain from 0.25 to 1.00% MoS2. When

Molybdenum Processing - IMOA

The chemical reduction of pure molybdenum trioxide or ammonium dimolybdate to metal requires two stages because conversion directly to metal releases heat that inhibits the process. The first stage reduction to MoO 2 is performed in the 450-650°C range. Molybdenum dioxide is then reduced to molybdenum metal in second stage reduction, using temperatures in the 1,000-1,100°C range.

Molybdenum processing Britannica

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. The concentrates contain between 85 and 92 percent MoS

When copper minerals are effectively suppressed, a certain amount of non-polar oil is added to the molybdenum floatation process to achieve the purpose of enhancing the flotation efficiency of molybdenite. In addition, in order to maximize the grade of molybdenum concentrate, it is necessary to add regulators such as inhibiting gangue minerals (water glass, etc.), dispersed ore pulp, etc., and perform 6 to 14 selections to obtain high-quality molybdenum

The organic selectively removes copper ions from the solution in exchange for hydrogen ions. The two phases are then separated, leaving copper-rich organic solution, and an acidic low copper aqueous solution. The aqueous layer is used for more copper leaching, whereas the organic is sent to the stripping stage. The copper is then removed from the organic layer using a strongly acidic solution. The result is a very pure copper
