The test result shows:(1) Concentration after grind finely, multi product configuration, regrind and reconcentratipn of sulphide iron ore, and firstly recovering tin and removing sulfide ore as possible as are available metholds to improve the grade and recovery of tin concentrate, simplify technology flowsheet and reduce production cost;(2) Intensifying the recovery of single stage concentration table is the key to concentration to concentration after grind firely and improving index. The recovery of fine tin is sure to further improve index;(3) Regrind and reconcentration of ferro-sulphur ore may recovery some tin.

试验研究结果表明：(1)细磨入选，多产品结构，硫化铁矿物再磨再选，能拿早拿、能丢早丢，预先脱出硫化矿物是提高锡精矿品位和回收率，简化工艺流程，降低生产成本的有效途径；(2)强化一段摇床的回收是细磨入选，提高指标的关键，细粒锡石的回收是进一步提高指标的根本保证；(3)硫铁矿物再磨再选也可回收部分锡金属。

Iron ore ; high sulphur magnetite ; floatation

铁矿石；高硫磁铁矿；浮选

About 30% of sulphur in the ore was oxidized to be SO〓, the other in residue and most of which was in form of α-S. The leaching results were combining efficiency of HNO〓, Fe〓, Cu〓 and O〓, and NO〓 in the leaching solution could be recovered and recycled.

矿物中约30%的硫被氧化成SO〓，70%留于渣中，除少量为硫化物形式，绝大部分以α-S单质存在，浸出过程硝酸可回收循环利用。

Iron ore ; sulphur ; occurrence ; mineral property

铁矿石；硫；赋存状态；矿物特征

A model for predicting the sulphur content in hot metal based on neural networks is introduced. Blast temperature, blast flux, top temperature, burden, coal injection rate, sulphur content in ore, sulphur content in coke, sulphur content in coal and silicon content of last tap were selected as inputs. The inputs were treated with time lag to improve prediction.

采用3层BP神经网络来预报高炉铁水硫含量，根据高炉冶炼的实际生产数据，选取风温、风量、炉顶温度、焦炭负荷、喷煤量、矿石硫含量、焦炭硫含量、煤粉硫含量和上一炉铁水硅含量9个因素作为输入变量，为提高神经网络预报的准确率，对输入参数进行时滞处理。

Figure 2 shows the jigging concentrate relations between content and ore feeding volume, when the diaphragm jig and the sawtooth pulsation jig are provided with different ore volume. Figure 3 shows the jigging concentrate relations between the sulphur recovery rate and ore feeding volume. As the test result shows, when the tailing content reaches approximately 7%, the diaphragm jig has 1.00 t / h · m2 feeding volume, which is also the maximum sorting efficiency in the test. As such, the sawtooth pulsation jig could choose 1.2 t / h · m2 feeding volume. As the test contrast of two groups shows, the sawtooth pulsation jigging concentrate contains higher-grade sulphur than the diaphragm jigging concentrate does.

图2为隔膜跳汰机及锯齿波跳汰机在不同给矿量的情况下，跳汰精矿品位与给矿量的关系，图3为跳汰机精矿硫回收率与给矿量的关系，试验结果表明，在尾矿品位接近7%，隔膜跳汰机给矿量为1.00 t/h·m2指标是隔膜跳汰机给矿量试验中选别效率最高的点，同理选择锯齿波给矿量为1.2 t/h·m2，将两组试验数据比较可以看出，锯齿波跳汰精矿含硫品位高于隔膜跳汰精矿含硫品位。
