A kind of application of the based compound containing peroxide
Technical field
The present invention relates to a kind of applications of based compound containing peroxide, belong to non-ferrous metal ore technical field.
Background technology
In non-ferrous metal ore technique, the selection of inhibitor is to improving mineral processing index important in inhibiting.Common lead, Bismuth, antimony sulphide ore inhibitor can be divided into two class of inorganic inhibitor and organic inhibitor.Inorganic inhibitor mainly has sodium sulfite, again Chromate, vulcanized sodium, sodium thiosulfate, cyanide etc..Organic inhibitor includes mainly thioacetic acid, carboxymethyl cellulose, gathers Acrylamide, dextrin etc..
Organic inhibitor is more with quantity, source is wide, is suitable for a variety of needs, and can be according to certain minerals system and reality Border needs the advantages that coming flexible design agent molecule structure and functional group.But due to the electrochemical properties of sulphide ore, sulphide ore has For machine inhibitor with other medicament obvious differences on molecular structure and performance, this is also organic inhibitor in sulfide flotation It is sodium thioglycolate industrially to apply rare reason, the organic inhibitor being industrially applied successfully at present.
Vulcanized sodium is one of most widely used bismuth in current industrial, lead, antimony sulphide ore inorganic inhibitor.It is floating in sulphide ore It chooses, the amount of sodium sulfide as inhibitor is larger.In floatation process, if amount of sodium sulfide is insufficient, inhibition cannot be reached The effect of lead, bismuth, antimony sulphide ore can activate other sulphide ores, floatation indicators is caused to be deteriorated instead;When dosage is excessive, and it can produce Raw reagent removal effect so that other floating agent dosages greatly increase, and cause that the production cost increases.Therefore, make using vulcanized sodium For inhibitor when, need reasonably control vulcanized sodium dosage and action time, this is more demanding to the operation of flotation worker, with Produced on-site requires the principle of simple and stable to run counter to.Meanwhile when using vulcanized sodium, easily generating hydrogen sulfide gas, hydrogen sulfide For toxic gas, the life and health of people is adversely affected.
Therefore, how to develop it is a kind of efficiently, nonhazardous, the strong lead of selectivity, bismuth, antimony sulphide ore inhibitor be currently to select In mine technology one of the problem of urgent need to resolve.Currently, using the compound of peroxy is contained as lead, bismuth, antimony in floatation process The technology of sulphide ore inhibitor, is also rarely reported in pertinent literature.
