Abstract
The invention discloses a method for emulsifying a molybdenum beneficiation collecting agent, comprising the following steps of: (1) putting sodium alkyl benzene sulfonate of an emulsifier into hot water the temperature of which is higher than 65 DEG C, stirring for 10min so as to enable the emulsifier to be sufficiently dissolved, wherein the mass ratio of sodium alkyl benzene sulfonate to the water is 1:5; (2) mixing 0.02-0.1 mass percent of emulsifier obtained in the step 1 and 6-10 mass percent of diesel oil, 1-2 mass percent of sodium silicate and 92.98-87.9 percent of water, stirring for 20min, and then obtaining a mixed liquor of the collecting agent; and (3) injecting the mixed liquor of the collecting agent which is obtained in the step 2 to a high shear emulsification pump, shearing and then circulating 2 times, and finally obtaining the emulsified collecting agent. The invention improves the water solubility and the dispersity of the collecting agent and reduces the final tailings grade, and the total yield is 0.5 percent higher than that of a process singly using the collecting agent. Meanwhile, the unit consumption of the collecting agent is reduced by 20 percent, and the unit consumption of a foaming agent is reduced by 9.5 percent.
Description
Technical field
The invention belongs to molybdenum technique of preparing field, what relate generally to is a kind of emulsification method of molybdenum beneficiation collecting agent.
Background technology
At present, used collecting agent is diesel oil substantially in the molybdenum technique of preparing.Because the structurally not only nonpolarity functional group of diesel oil but also nonpolarity, and all be to pass through covalent bonds in the hydrocarbon atom in whole molecule, and be in saturation state, so the diesel oil chemism is very low, in the aqueous solution, can not ionization go out ion, chemisorbed or surface chemical reaction can not take place with the mineral surfaces effect, can only rely on physical adsorption way and mineral surfaces to have an effect by Van der Waals force, because of diesel oil is insoluble in water, its water-soluble and dispersiveness in ore pulp is lower, mainly exist with oil droplet state (molecule aggregation body), the oil film that forms at mineral surfaces is also thicker, contacts insufficiently with ore particle, causes recovery rate in ore-dressing to be difficult to further raising.
Summary of the invention
The objective of the invention is to propose a kind of emulsification method of molybdenum beneficiation collecting agent, make it can improve collecting agent water-soluble and dispersed in ore pulp, and then improve recovery rate in ore-dressing.
The technical solution used in the present invention is for achieving the above object: the emulsification method of molybdenum beneficiation collecting agent may further comprise the steps:
(1) the emulsifying agent sodium alkyl benzene sulfonate is put into hot water more than 65 ℃, stirred 10 minutes, it is fully dissolved, the mass ratio that alkyl benzene sulphonate is received with water is 1: 5;
(2) emulsifying agent that step (1) is obtained and diesel oil, sodium metasilicate, water are by mass percentage: emulsifying agent 0.02～0.1%, and diesel oil 6～10%, sodium metasilicate 1～2%, water 87.9～92.98% mixes, and stirs the mixed liquor that obtained collecting agent in 20 minutes;
(3) the collecting agent mixed liquor that step (2) is obtained is squeezed into the high-shear emulsifying pump and is sheared, and recirculation is sheared 2 times, obtains the collecting agent of emulsification.
Mixed liquor of the present invention is after three high speed shear of emulsification pump, the emulsifying agent molecule can produce at the small oil droplet through high speed shear and align, non-polar end (oleophilic drainage base) is towards oil droplet inside, polar end (hydrophilic oleophobic machine) is towards the aqueous solution, so form hydrated sheath on small oil droplet surface, the hydrated sheath that makes emulsified dose of small oil droplet and form surrounds, at this moment small oil droplet collides mutually or contacts and is difficult for annexing, and remain more stable emulsion state, water-soluble dispersed strengthen of diesel oil in ore pulp after the emulsification, contact more abundant with ore particle, can improve the collecting effect of diesel oil, reduce the beneficiation reagent consumption, improved the water-soluble and dispersed of collecting agent, reduced the true tailings grade, the overall recovery ratio is high by 0.5% when using collecting agent separately.Simultaneously, the collecting agent unit consumption descends 20%, and the foaming agent unit consumption descends 9.5%.
