Description
Technical field
The utility model belongs to potassium mine desliming device technical field, and in particular to a kind of desliming system of the high mine of potassium containing mud.
Background technology
Sylvite has in a variety of industrial circles such as agricultural, chemical industry, medicine, weaving, printing and dyeing, process hides, glass, ceramics and explosive
It is widely applied, however China's potassium resource is deficient, largely relies on import.China's KCl production is concentrated mainly on Qinghai Province, so
And with the raising of production capacity, the consumption aggravation of high-grade raw ore, in Salt Lake Area, remaining solid kalium mine resource is essentially height
Containing mud, the low solid mineral containing potassium, wherein cement content is more than 30%.This part height potassium containing mud mine is producing potassium chloride using floatation
During, the presence of a large amount of sludges can generate the flotation of sylvite important influence, be mainly shown as that sludge can be covered in mesh
The surface for marking mineral potassium chloride and flotation bubble hinders the absorption of collecting agent and target mineral and bubble, reduces flotation effect
Rate；Sludge is since particle is thinner, thus specific surface area is larger, and in target mineral floatation process, sludge can be carried out with medicament
Absorption, to consume a large amount of medicament；The presence of sludge also will increase the viscosity of entire floatation system and change flotation froth
Stability.Therefore, finding a kind of rationally efficient potassium mine Desliming method seems particularly significant.
Currently, the Desliming method of existing salt lake potassium mine mainly has medicament desliming and mechanical two kinds of desliming.Such as Russia
Ural potassium company has carried out flotation in the potassium mine of 4-6% to clay content as collecting agent using hydroxyethylated fatty amine and has desilted,
The result shows that desliming efficiency can reach 56%.Russian Wei Heliekamusike (BexHeKaMCK) mineral deposit Bie Leizilikefusi
Gram mining area potassium ore is sent to Ural flotation mill of potassium company and is handled, the results showed that, using hydroxyethylation amine as collecting agent
The rate of recovery that insoluble impurity in slime product can be improved improves the selectivity and flotation speed of slime flotation, reduces sylvite
Flotation meets workshop large-scale production to the content of the insoluble impurity in mine the disadvantage is that the process ability is relatively small
It is more difficult.To the inhibition of water-insoluble, as a result S Ji Tekefu have studied the KC-MF inhibitor of urea and formaldehyde synthesis
When showing using KC-MF inhibitor, the grade of Potassium Chloride Product can improve 1%, and the dosage of collecting agent can reduce by 20%, but the suppression
Preparation is only for the relatively low situation of cement content.Chen Xiaoqing etc. use the fatty amine containing ethyoxyl as collecting agent to potassium mixed salt into
Gone flotation desliming, desliming efficiency can reach 50.87% or more, but the directly production of the potassium mine after desliming still have it is certain
It is difficult.Xiong Wenliang etc. carries out desliming as collecting agent using petroleum sodium sulfonate to Qinghai potash feldspar ore, the results showed that in desliming
While can also remove the ferrous contaminants such as garnet, tourmaline in ore, but this collecting agent desliming efficiency is relatively
It is low.
It is firstly added the flocculants such as polyacrylamide in patent US4192737A to settle water-insoluble, then uses containing combustion
Expect that the mixtures such as oil, aliphatic acid are collecting agent flotation desliming.It is to be firstly added polyphosphazene polymer mixture to incite somebody to action in patent US3805951A
Mud settles, and a kind of cation-collecting agent flotation slurry is then added.Polypropylene is added in ore pulp first in patent SU810286
Amide flocculant stirs one minute, then adds dimethylamine ethyl methacrylate and vinylacetate and iodomethane quaternary ammonium
Compound after change is as collecting agent desliming, but the technical matters flow is more complex and used collecting agent residue may
The production of follow-up potassium mine can be affected.It is by the way that modified Lauxite is added in slurry in patent US2006226051
Clay dispersion is reduced into influence of the clay to sylvite flotation, but the disadvantage is that the sludge after dispersion can stay in the entire system, still
Potassium mine flotation can so be had an impact.Desliming in patent SU1168290 is by adding modified wood in production technology
Slurry byproduct, polyacrylamide and ethyoxyl alkyl phenolic ester, the rate highest of desilting can be to 68.8%, the disadvantage is that potassium chloride loss amount
It is relatively large.The patent authorized before applicant《A kind of fluid mud agent and the mine of potassium containing mud desilt technique》It is middle to use kerosene as collecting
Agent carries out flotation desliming, and desliming efficiency is higher, but remains influence of the floating agent to sylvite product and be difficult to assess.
Another Desliming method is mechanical desliming, for example the M.R.Yalamanchili of Univ Utah USA is taught in reality
It tests room and uses Air-sparged hydrocyclones（ASH）The sludge of U.S. Saskatchewan Wenzhou Jia Kuang factories is handled, as a result
Clay content is only 7% in the potassium mine for showing that desliming rate can reach 70%, but being studied.М Г thank to remote golden Na and use dry type magnetic separation
Machine to sylvite ore carry out desliming, the results showed that clay content 4-14% potassium mine after selected desliming, the content of sludge is apparent
It reduces.Desliming, although desliming efficiency is higher, the party are carried out using the technique of eddy flow-screening in patent CN102350399 A
Method does not add grinding attachment, causes potassium mine and part sludge that cannot efficiently separate, and potassium mine is lost while removing sludge
It is larger.
The method that sludge is handled can play to the purpose of desliming to a certain extent above by addition medicament, but due to
A kind of medicament is often added in this method in systems, and the influence that this medicament produces follow-up potassium mine is difficult assessment, and
The loss of mechanical desliming potassium mine while effective desliming is relatively large.Therefore, rational desliming technology is studied to solve sludge
Influence to KCl production is to improve the key means of resource utilization, is urgently to be resolved hurrily in potassium resource process ask
Topic, has important practical significance to the sustainable development of salt lake resources.
