Abstract
The invention provides a process for ore pulp desliming and ore slurry dehydration, which relates to a mineral processing process. The process comprises the steps of: a, removing large dreg of ore pulp raw materials by using a dreg separation sieve; b, removing impurities of the ore pulp raw materials without the large dreg by adopting a sorting filter and enabling the ore pulp raw materials to enter a sorting machine to be subjected to desliming and selection to obtain deslimed ore pulp and ore slurry; c, enabling the deslimed ore pulp to enter a floating selection procedure; after removing the impurities of the ore slurry with a dehydrating filter, enabling the ore slurry to enter a dehydrating machine to be concentrated and dehydrated so as to obtain concentrated ore slurry and reusable process pure water. The process is simple and reliable; the concentration and the grade of the ore slurry are improved and the desliming is complete; rapid concentration and dehydration of the ore slurry are realized; the process has important effects in the aspects of improving the stability of selection work and the grade and the recovery rate of ore concentrates, reducing the use amounts of a floating selection medicament and pure water and the like.
Description
Technical field
The present invention relates to a kind of ore-dressing technique, be specially the technique of a kind of ore pulp desliming and sludge dehydration.
Background technology
Sludge in the ore dressing term refers generally to the grade material of granularity<10um, according to current ore-dressing technique level, in selected material<the 10um grade is difficult to effective recovery, and assorting room disturbed, affect concentrate taste and the rate of recovery, increase reagent consumption.Therefore, the high material for clay content, should need to remove in advance sludge wherein according to technique, main desliming bucket or two kinds of equipment of water conservancy cyclone of adopting carry out desliming at present, but its desliming efficiency is lower, selected material clay content is higher, purpose mineral loss late is bigger than normal, is unfavorable for the raising of technique of preparing economic indicator.At present desliming process commonly used is to adopt water conservancy cyclone to carry out a desliming, in its sand setting (or underflow)<the 10um grain size content is generally 20 ~ 30%, in overflow>the 10um grain size content is generally more than 30%.The classification matter efficiency of a desliming process of hydrocyclone is 50% left and right only,>10um grade loss late 20% left and right, and the desliming effect of desliming bucket is poorer.
Summary of the invention
The objective of the invention is to solve that current desliming process is complicated, the poor problem of effect, a kind of efficient desliming, dewatering process are provided, can will be selected in the material clay content and purpose mineral loss late reduces greatly.
The technical scheme that realizes above-mentioned purpose is: the technique of a kind of ore pulp desliming and sludge dehydration is characterized in that: comprise the following steps: a, by raw material of ore by remove large slag every ballast screen; B, except the raw material of ore after large slag enters separator after the impurity elimination of sorting filter, carry out desliming and selected, obtain desliming ore pulp and sludge slurry; C, desliming ore pulp enter flotation process, and the sludge slurry enters dewaterer and concentrates and dewater after the dehydrator filter impurities removal, obtain thickened slurry slurry and recycling technique water purification.
Above-mentioned separator is the disc type separator, and above-mentioned dewaterer is disk type dehydrator.
This simple and reliable process, improved pulp density and grade, and desliming is thorough, and realized the concentrated and dehydration fast of sludge slurry; For the aspects such as stability, concentrate grade and the rate of recovery, reduction floating agent and water purification consumption that improve sorting operation, play an important role.
The accompanying drawing explanation
Fig. 1 is process chart of the present invention.
The specific embodiment
Illustrate implementation step of the present invention below in conjunction with accompanying drawing 1:
A, by raw material of ore by every ballast screen 1, removing large slag, send into ore pulp tank 2 except after large slag;
B, by ore pulp feed pump 3 by 4 impurity eliminations of the raw material of ore in ore pulp tank 2 input sorting filter;
C, the input of the raw material of ore after 4 impurity eliminations of sorting filter separator 5 carry out desliming and selected, obtain desliming ore pulp and sludge slurry, and the desliming ore pulp enters flotation process, and the sludge slurry is sent into ore deposit slurry tank 6;
Sludge slurry in d, ore deposit slurry tank 6 is starched feed pump 7 input dehydrator filter 8 impurities removals by sludge, and the sludge slurry enters dewaterer 9 and concentrates and dewater after dehydrator filter 8 impurities removals, obtains thickened slurry slurry and recycling technique water purification.
Above-mentioned separator 5 is the disc type separator, and above-mentioned dewaterer 9 is disk type dehydrator; Disc type separator and disk type dehydrator are disk centrifugal separator of the prior art, at this, are not repeating.
