贵州省煤系硫铁矿石选矿试验

Test on pyrite ores in coal series

定量考察了硫铁矿石在存放过程中，由于空气中氧和水份的作用使低价硫逐渐被氧化为高价硫的过程。

It was found that the low-valent sulfur is gradually oxidized to high-valent sulfur by oxygen and water when exposed to air , which is the main reason for the unstability .

针对煤系硫铁矿精矿含碳较高不利于焙烧制酸的问题，为了有效利用煤系硫铁矿，以云南某高碳煤系硫铁矿石为试验矿样进行了降碳提硫研究。

In view of the high carbon content in the coal-derived pyrite which is unfavorable for making acid , research on carbon reduction and sulfur lift was carried out using a high carbon coal-derived pyrite ore from Yunnan as test sample in order to efficiently utilize the coal-derived pyrite .

碎屑型矿石是东升庙多金属硫铁矿床的主要矿石类型之一。

Of the ore types in the Dongshengmiao polymetallic sulfide deposit , the clastic type is an important one of them .

提出可用全硫（TS）作为硫铁矿石稳定性的监测项目。

Total sulfur content is suggested as the monitoring item for the change of the material .
