Extraction - molybdenum

The extraction of molybdenum. Molybdenum comes from a sulphide ore called molybdenite. First, the ore must be crushed into a powder and then the copper sulphide must be separated from the rest. What is left is molybdenum sulphide and that is roasted. Now there is molybdenum concentrate and that is then made into molybdenum oxide. After that, the molybdenum oxide "goes through a two-step ...

Molybdenum: mining and processing-Metalpedia

Molybdenum mines are classified into three groups according to the minerals contained in the ore body and their quality: •Primary mines, where the extraction of molybdenite is the sole aim. •By-product mines, where the extraction of copper-bearing ores is the primary aim, and molybdenite extraction provides additional economic value.

2005-06-01  The percentage molybdenum extraction vs. temperature is shown in Fig. 1, which suggests that, at around 900 °C, extraction of molybdenum is 70%. A further increase in temperature leads to gradual decrease in molybdenum recovery, which may be attributed to the gradual vaporization of sodium molybdate.

2019-09-05  Molybdenum exists in many minerals, but only molybdenite (MoS2) is suitable for the industrial production of molybdenum products. Molybdenite may be the only mineralized mineral in a single ore body, but it usually co-exists with other metals, especially copper sulfide minerals. The molybdenum content of each ore body is between 0.01 and 0.25%.
