Background technique
In non-ferrous metal ore technique, the selection of inhibitor is to raising 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 mainly includes 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 to come the advantages that 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
Rare reason is industrially applied, the organic inhibitor being industrially applied successfully at present is sodium thioglycolate.
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 instead, floatation indicators is caused to be deteriorated；When dosage is excessive, and it can produce
Raw reagent removal effect causes that the production cost increases so that other floating agent dosages greatly increase.Therefore, make using vulcanized sodium
