Abstract
The invention relates to a dissociation method of barite and gangue ores. According to the dissociation method, barite ores are grinded at first and then calcined at a temperature of 120 to 300 DEG C; and finally processed ores are grinded and screened for another time to obtain barite concentrate and barite tailings. Through calcining, fluorite ores in barite and gangue are fully dissociated; the grade of obtained barite concentrate is high, the content of barite can reach 95% or more; during the dissociation process of barite and gangue ores, no any chemical reagent is added, chemical-free sorting is realized, and the barite concentrate will not be polluted by chemical reagents.
Description
Technical field
The invention belongs to Mineral Processing Engineering field, be specifically related to the dissociating method of a kind of barite and gangue mineral.
Background technology
China's barite deposit lean ore is many, rich ore is few, and the baryte deposit of proved reserves has 80% to be above and other mineral associations, especially with fluorite ore association.In carbonate and many metals symbiosis fluorite deposit, barite is close with fluorite symbiosis, it is difficult to dissociate.
Li Mingfeng points out in " fluorite is studied with Barite flotation separation test ": fluorite separates with barite and generally uses floatation process at present.Technique is roughly divided into three classes: fluorite separates with barite and generally uses floatation process at present.Technique substantially can be divided three classes: the first kind is first to suppress other gangue minerals, and bulk flotation cyclopean and barite obtain melitic barite bulk concentrate, then carry out the separation of fluorite and barite.The method, owing to can obtain qualified fluorite and barite concentrate simultaneously, is therefore used widely in commercial production, but experiment flow is complex；Equations of The Second Kind is suppression barite, diffeential floatation fluorite.High-quality melitic concentrate can be obtained by the method, but repressed barite can not be recycled utilization owing to being difficult to activate.3rd class is suppression fluorite, diffeential floatation barite, and the method flow process is the simplest, it is possible to obtain qualified barite concentrate, but fluorite concentrate is difficult to reach acid level fluorite standard.
Summary of the invention
The present invention combines the symbiotic characteristic of barite and fluorite, it is provided that a kind of by barite and the abundant dissociating method of fluorite mineral, it is achieved barite dissociates with gangue mineral, it is thus achieved that barite concentrate grade height, and technological process is simple.
Technical solution of the present invention is: a kind of barite and the dissociating method of gangue mineral, and the barite deposit after first crushing, 120 ~ 300 DEG C of roastings, then carries out gravity treatment after ore grinding and obtains barite concentrate and barite mine tailing.
Described barite deposit is barite and fluorite mineral intergrowth.Such as, described barite deposit is carbonate and/or many metals symbiosis fluorite ore.
Preferably, barite deposit is crushed to granularity 15 ~ 12mm.
Disintegrating apparatus can use jaw crusher, impact breaker, hammer mill, gyratory crusher or kibbler roll.
Preferably, roasting time 30min ~ 60min.
Roasting apparatus can use rotary kiln, rotary furnace or tunnel cave.
Preferably, ore grinding accounts for 60 ~ 90% to-0.074mm.
Grinding attachment can use ball mill or rod mill.
Gravitational separation equipment can use 6S shaking table, spiral chute or jigging machine.
The principle of the invention: barite separates difficulty with gangue mineral, reason is and fluorite minerals separation difficulty in stone-like pulse.Barite is close with the physicochemical property of fluorite, it is difficult to separate by mineral processing methods such as flotation, gravity treatment or magnetic separation.But, have certain joint plane between barite and fluorite mineral, by roasting so that barite dissociates along joint plane with fluorite mineral, and then barite be enriched with by reselection modes.
The method have the benefit that
1) utilize roasting to achieve barite fully to dissociate with fluorite mineral in stone-like pulse, particularly from the fluorite deposits such as carbonate or the symbiosis of many metals, isolate barite so that barite and gangue mineral dissociate, it is thus achieved that barite concentrate grade high, up to more than 95%；
2) barite is with gangue mineral dissociation process, without any chemical agent, it is achieved sort without medicament, pollutes barite concentrate without chemical agent.
