Abstract
The invention discloses a collecting agent and an ore selection method of jordisite. The collecting agent is formed by mixing a sodium naphthalene sulfonate water solution and a butyl xanthate water solution in a weight ratio of (1-3):1, wherein the mass concentration of the sodium naphthalene sulfonate water solution is 2-4% and the mass concentration of the butyl xanthate water solution is 5-8%. The ore selection method of the jordisite disclosed by the invention comprises the following steps of: adding a raw ore containing the jordisite into a sodium trithiocarbonate water solution to carry out medicating and ore grinding, so as to obtain ore slurry of the raw ore; and adding an inhibitor and the collecting agent provided by the invention into the ore slurry of the raw ore, and carrying out flotation work to obtain a molybdenum concentrate product. The collecting agent and the ore selection method of the jordisite have the characteristics of low medicament dosage, good stability, high molybdenum grade and high recycling rate and are very suitable for the selection of the jordisite; and the grade of a molybdenum concentrate can be more than 30% and the recycling rate of the molybdenum can be more than 90%.
Description
technical field [0001] The invention relates to the field of mineral processing, in particular to a collector. In addition, the present invention also relates to a beneficiation method of glauside molybdenum ore using the above-mentioned collector. Background technique [0002] Molybdenum is an important rare metal and strategic reserve resource, which plays an extremely important role in the entire national economy. At present, 99% of molybdenum production in the world is obtained from molybdenite. The resource recovery of other molybdenum minerals is rarely studied. Sulfurite is another type of molybdenum sulfide ore, mainly distributed in Germany, the United States, Chile and China, and its grade is much higher than that of molybdenite, and its resource value is very large. However, different from molybdenite, the properties of sulfomolybdenite are very complex and difficult to separate. Since the discovery of sulfomolybdenite, there has been no systematic research rep...
