Description
First, technical field
The present invention relates to the flotation separation method of stibnite and realgar separation method, particularly a kind of stibnite and realgar.
2nd, background technology
Floatability is preferable in acid condition with realgar mineral for stibnite, in the basic conditions, as stibnite has alkali
Dissolubility and floatability are deteriorated, and now realgar mineral floatability is better than stibnite, but floatability difference is not obvious, therefore, no matter
Under acid or alkalescence condition, the FLOTATION SEPARATION of stibnite and realgar mineral all becomes relatively difficult, while in neutral conditions
It is difficult to find the selective depressant of realgar mineral, therefore this kind of ore typically carries out collecting using a small amount of collecting agent to stibnite
Afterwards again in smelting process to separating, but smelting cost is high, and environmental protection pressure is big, if realize in ore dressing process brightness antimony with
This kind of mineral are had theoretical and realistic meaning by the FLOTATION SEPARATION of realgar mineral.
3rd, content of the invention
It is an object of the invention to provide the flotation separation method of a kind of stibnite and realgar, it is obtained in that low arsenic antimony essence
Ore deposit.
The present invention is employed the following technical solutions and reaches above-mentioned purpose：A kind of stibnite and the flotation separation method of realgar, institute
With the content of antimony in raw mineral materials be 1.35～3.12%, quartz content be 12.02～15.27%, arsenic content be 1.54～
3.63%th, calcium carbonate shows through material phase analysis containing 3.87～5.94%, the main antimony containing brightness of valuable mineral in ore, on a small quantity crisp sulphur
Antimony lead ore deposit；Gangue mineral realgar, a small amount of mispickel；Other impure minerals are mainly calcite, quartz and aluminum silicon mineral.
Concrete steps and regime of agent are as follows：
(1) under the conditions of natural pH,
(2) causticity tapioca and ironic citrate are adopted as the inhibitor of realgar mineral,
(3) make stibnite thing activator with plumbi nitras
(4) make the collecting agent of stibnite with diethyldithiocarbamate and butyl xanthate,
(5) make foaming agent with 2# oil,
(6) in floatation process, after ore ore grinding to mineral monomer is dissociated, under the conditions of natural ph, using causticity wood
Sweet potato starch makees stibnite thing activator with ironic citrate as the inhibitor of realgar and other impure minerals, with plumbi nitras, uses second
Sulphur nitrogen makees the collecting agent of stibnite with butyl xanthate, and making foaming agent with 2# oil carries out collecting to stibnite.
(7) dosing is：
During use, the medicament is first configured to following concentration expressed in percentage by weight：
The present invention has the prominent advantages that：
1st, stibnite and realgar mineral FLOTATION SEPARATION can be made, under the conditions of being 1.35～3.12% to ore deposit antimony grade, is obtained
It is 45.17～52.04% to obtain antimony grade, and the rate of recovery is 87.33～91.20% antimony concentrate, and antimony concentrate arsenic content is only 0.33
～0.42%.
2nd, flowage structure is simple, and dosing is few.
