Embodiment 1

[0023] A kind of flotation method of molybdenum oxide ore, comprises the following steps:

[0024] (1) Grinding: The ore feed material is molybdenum sulfide ore flotation tailings in a certain place, containing 0.095% molybdenum, and the oxidation rate of molybdenum is over 95%, mainly molybdenum-calcium ore. The grinding fineness is -0.074mm reaching 85%, and the dissociation degree of molybdenum-calcium ore monomer is 88%.

[0025] (2) Desliming: Gravity separation and desliming is performed on the ore pulp treated in step (1), and 5.5% fine mud is removed by gravity separation.

[0026] (3) Flotation of molybdenum oxide ore: Add adjusting dispersants sodium carbonate and water glass to the pulp described in the above step (2), the dosages are 1000g / t and 1500g / t respectively, adjust the pH of the pulp to 9, add inhibitory agent sodium hexametaphosphate and sodium carboxymethyl cellulose, the dosage is respectively 120g / t and 60g / t, then add the combined collector, the dosa...

Abstract

The invention discloses a method for using a molybdenum oxide ore flotation collector. The weight parts of the combined collector are 100-400 parts of α-amino acid, 20-80 parts of kerosene, and 10-40 parts of ethylthiocarbamate; The method of using the collector is as follows: Grind the molybdenum sulfide flotation tailings containing molybdenum oxide to a fineness of -0.074mm, which accounts for 75% to 95%, use gravity classification to remove the fine mud, and then add in order to adjust the dispersant, inhibit agent, and the collector for flotation to obtain molybdenum oxide concentrate products. The molybdenum oxide combined collector provided by the invention has the characteristics of good selectivity, less reagent consumption and high recovery rate.

Description

technical field [0001] The invention belongs to the field of mineral processing, and in particular relates to a combined collector for flotation molybdenum oxide from molybdenum sulfide flotation tailings and a use method thereof. Background technique [0002] Molybdenum is a non-renewable strategic mineral resource. Due to its unique properties, it is widely used in steel, military, aerospace, electronics and other industries. With the development of society and economy, the demand for molybdenum is increasing. reduce. [0003] Molybdenum in nature mainly exists in the form of sulfides such as molybdenite. Molybdenum sulfide minerals can be better utilized by conventional flotation beneficiation process because of their natural buoyancy. The other molybdenum exists in the form of molybdenum-calcium ore, molybdenum-lead ore and other oxide ores. Molybdenum oxide ores are difficult to be effectively recycled by conventional beneficiation processes because of their poor selec...
