Description
Technical field：
The present invention relates to a kind of method for floating of sulphur in association troilite, belong to ore-dressing technique, technical field of resource comprehensive utilization.
Background technology：
When it is high sulfide pyrite to contain association pyrite in iron mineral, need to carry out desulfurization process.Sulfur content is to weigh iron ore concentrate
One of leading indicator of quality height, according to the requirement of smelting iron and steel it is found that sulfur content raising 0.1% in iron ore concentrate, coke ratio will rise
It is high by 5%, and the raising of coke ratio is unfavorable to blast furnace ironmaking, therefore the lower the sulfur content of iron ore concentrate the better.Meanwhile in iron ore concentrate
Sulphur in smelting process, can partly be discharged in the form of gaseous sulphide such as sulfur dioxide with furnace gas, and in regional area
Aggregation can be dissolved in water when encountering water and form sulfurous acid, then under the catalysis of other chemical substances and oxidizing effect
Sulfuric acid is generated, sedimentation forms acid rain, causes serious environmental pollution and harm.Therefore, iron ore concentrate sulfur-bearing is controlled relatively low
It is horizontal extremely important.If can be recycled while high sulfide pyrite effective desulfurization to Sulphur ressource, there will be significant warp
Ji and social benefit.
Ferro-sulphur ore comprehensively utilizes, and is exactly except using in addition to sulphur therein, while recycles iron and associated metal.Including Huang
A kind of essential mineral in iron ore troilite, the mostly association in coloured, polymetallic deposit, single pyrite deposit take second place.At present
The existing effective recovery process of pyrite in single pyrite deposit, such as Yunfu Sulfur-Iron Ore Enterprise Group Corp..However,
While high sulfide pyrite effective desulfurization, the Comprehensive Recovery Technology shortcoming of the association troilite in iron ore is recycled, companion in iron ore
The synthetical recovery of raw troilite requires that the recycling of pivot plain sheet cannot be influenced, and simultaneously to obtain technical indicator high as possible,
With maximum economic benefit.
The desulfurization of association troilite at present mostly using floatation process, after raw ore ore grinding to qualified fineness, adds in flotation medicine
Agent by roughing and several sections of selected operations, finally obtains iron concentrate and flotation iron ore concentrate, iron concentrate sulfur grade 30% or so,
For sulfur recovery rate between 60%-70%, iron concentrate sulfur grade and the rate of recovery are relatively low, influence the recycling of Sulphur ressource.Flotation iron
Concentrate sulfur-bearing fluctuates between 0.35%-0.55%, and it is exceeded to easily lead to final iron ore concentrate sulfur-bearing, influences concentrate sale.
Invention content
The purpose of the present invention is providing a kind of method for floating of sulphur in association troilite in view of the above problems, reduce
The iron concentrate product of better quality is obtained in iron ore concentrate while sulfur content, and improves the Sulphur ressource rate of recovery, this is to high sulfide pyrite
Stone desulfurization efficiently has important practice and theory significance using Sulphur ressource.
Above-mentioned purpose is achieved through the following technical solutions：
The method for floating of sulphur in a kind of association troilite, this method comprises the following steps：
