Abstract
The invention relates to a collecting agent and an application thereof to flotation of molybdenite. The collecting agent comprises a cross-linking agent sac100 and kerosene, and the mass ratio between the cross-linking agent and the kerosene is 1: (5-8). The collecting agent is applied to the flotation of the molybdenite. By means of the collecting agent, the recovery rate of floating separation molybdenite can be increased by 4 percentage points in average.
Description
Technical field
The present invention relates to mineral processing flotation technology, be specifically related to a kind of collecting agent and the application in molybdenite flotation thereof.
Background technology
Collecting agent is the most important medicament of flotation production technology.Collecting agent changes solid mineral surface hydrophobic, makes the solid ore particle swum attach to floating agent on bubble.
Traditional molybdenite flotation technique be ore through fragmentation, ore grinding, flotation (roughly select+selected).Usually add collecting agent roughly selecting, conventional flotation optimum efficiency only reaches 90% for using the YC medicament rate of recovery.
Summary of the invention
For shortcoming or the deficiency of prior art, the invention provides a kind of collecting agent, this collecting agent comprises crosslinking agent sac100 and kerosene, and the mass ratio of described crosslinking agent and kerosene is 1: (5-8).
Described crosslinking agent sac100 isocyanates or glutaraldehyde are replaced.
For shortcoming or the deficiency of prior art, the invention provides above-mentioned collecting agent for the application in molybdenite flotation.
The invention has the beneficial effects as follows:
Use collecting agent of the present invention, select the rate of recovery average energy of molybdenum to improve 4 percentage points, when the rate of recovery of molybdenum improves 2-4 percentage point, the consumption of collecting agent of the present invention is suitable with kerosene consumption, called after D16.
Accompanying drawing explanation
Fig. 1 is molybdenite flotation flow chart, and wherein: K represents concentrate, N represents chats, and X represents mine tailing.
Detailed description of the invention
The molybdic-separating catcher that current Jin Dui city Mu Ye Group Plc uses is YC.Since Jin Mu company replaced kerosene to select molybdenum from 2006 with YC medicament, though process stabilizing, technical indicator is better than kerosene, and selects molybdenum technical indicator abroad, and particularly the rate of recovery is compared, and still has larger gap.
Therefore need a kind of new collector, good dispersibility must be had, so that expand the contact angle of hydrocarbon compound and selected mineral; There is the absorption affinity between stronger compound and selected mineral simultaneously, the rate of recovery of target minreal is improved.Based on above technical Analysis, on stream, this two large function of collecting agent is realized emphatically.
Inventor uses through Mutiple Choice, compare emulsifying agent, crosslinking agent, dispersant etc. without Long carbon chain organic compound, finally determine to use crosslinking agent and kerosene to carry out proportioning, reduce the shortcoming of Long carbon chain hydrocarbon ils disperse weak effect, do not reduce hydrocarbon ils in the wetting of molybdenite surface and diffusivity simultaneously, and improve the adsorption capacity of medicament for mineral, use this medicament can improve rate of recovery 2-4 percentage point in conventional flotation flow process.
Below the specific embodiment that inventor provides, to be further explained explanation to the present invention.
What adopt in following examples is flotation process in conventional chamber: sample preparation-ore grinding-flotation.Flotation flowsheet adopts a thick essence.Roughly select flotation time and be decided to be 2 minutes, selected flotation time is decided to be 1 minute.During ore grinding, floating agent is added in ball mill.
Embodiment 1:
Experimental condition: andesitic porphyrite type molybdenite 500g, grade 0.6%.Roughly select L=1.5 liter, selected L=0.75 liter.Roughly select t=2 to divide, selected t=1 divides.
Table 1 molybdenite flotation result of the test
Know from table 1, D16 to the collecting ability of molybdenum concntrate, apparently higher than YC medicament.The concentrate rate of recovery reaches 85.36%, and the chats rate of recovery reaches 6.81%, adds up to 92.17%, and uses YC medicament to be only 90.02%, improve 2.25 percentage points under equal conditions.Emulsifier effect is poor, and dispersant is not effective.
Embodiment 2:
Condition: andesitic porphyrite type molybdenite 500g, grade 0.8%, roughly selects L=1.5 liter, selected L=0.75 liter.Thick selected t=2 divides, and selected t=1 divides, and mixing time is 1 point, and flow process is with figure mono-, and molybdenite flotation result of the test is in table 2.
Table 2 mixes molybdenite flotation result of the test
Know from table 2, the collecting ability of D16 collecting agent to molybdenite is better than YC medicament, and when concentrate grade is suitable, the rate of recovery is high 4 percentage points.Emulsifier effect is poor, and dispersant does not reach the effect improving the rate of recovery.
Embodiment 3:
Condition: Granite molybdenite 500g, grade 0.8%, roughly selects L=1.5 liter, selected L=0.75 liter.Thick selected t=2 divides, and selected t=1 divides, and mixing time is 1 point, and flow process is with figure mono-, and granite porphyry molybdenite flotation result of the test is in table 3.
Table 3 Granite molybdenite flotation result of the test
Know from table 3, Granite molybdenite flotation, D16 collecting agent flotation effect is better than YC medicament equally.But gap obviously diminishes, the rate of recovery is about high 2 percentage points.Emulsifying agent, dispersant all do not reach the effect improving the rate of recovery.
