摘　　要：对云南某沉积型赤铁矿石进行了工艺矿物学研究,重点研究了主要铁矿物及主要脉石矿物的产出形式及粒度特征。研究表明,该矿石属低硫、高磷、细粒嵌布的赤(褐)铁矿矿石,主要铁矿物之间、铁矿物与脉石矿物之间嵌布关系复杂。根据工艺矿物学研究成果对提高铁精矿品位和回收率、降低铁精矿中的磷含量给出了建议。Took the process mineralogy research to Yunnan a sedimantary hematite ore,focusing on the main ore and gangue minerals output form and size characteristics.Research shows that,the ore is low sulfur,high phosphorus,fine disseminated hematite iron ore（limonite）,mainly iron ore,iron ore and gangue minerals between the complex relationship between inlay.Based on the process mineralogy research on improving iron concentrate grade and recovery,reduce the phosphorus content in iron ore concentrate is proposed.
