Method for emulsifying molybdenum beneficiation collecting agent

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, andthe unit consumption of a foaming agent is reduced by 9.5 percent.

Description

technical field [0001] The invention belongs to the technical field of molybdenum beneficiation, and mainly relates to an emulsification method of a molybdenum beneficiation collector. Background technique [0002] At present, the collector used in molybdenum beneficiation technology is basically diesel oil. Since diesel has neither polar functional group nor polarity in structure, and the carbon and hydrogen atoms in the whole molecule are bound by covalent bonds and are in a saturated state, the chemical activity of diesel is very low, and ions cannot be ionized in aqueous solution. It is impossible to have chemical adsorption or surface chemical reaction when interacting with the mineral surface. It can only interact with the mineral surface by means of physical adsorption through van der Waals force. Because diesel oil is difficult to dissolve in water, its water solubility and dispersibility in the pulp are low, mainly It exists in the state of oil beads (molecular agg...

Since diesel has neither polar functional group nor polarity in structure, and the carbon and hydrogen atoms in the whole molecule are bound by covalent bonds and are in a saturated state, the chemical activity of diesel is very low, and ions cannot be ionized in aqueous solution. It is impossible to have chemical adsorption or surface chemical reaction when interacting with the mineral surface. It can only interact with the mineral surface through van der Waals force relying on physical adsorption. Because diesel oil is difficult to dissolve in water, its water solubility and dispersibility in the pulp are low, mainly It exists in the state of oil beads (molecular aggregates), and the oil film formed on the surface of the mineral is thicker, and the contact with the ore particles is not sufficient, which makes it difficult to further increase the recovery rate of ore dressing
