一般认为硅酸铁是一种没有经济价值的脉石矿物,其含量决定一个铁矿是否有开采价值,而且是选择最有效的选矿流程和确定最佳选矿指标的重要依据。铁矿中硅酸铁的测定方法以往有化学分离法、重液分离法、选择还原法,选择氧化法等几类。较常用的是选择还原法,即600℃氢还原法。该法的主要缺点是,某些硅酸铁如绿泥石等, It is generally believed that iron silicate is a gangue mineral with no economic value. The content of iron silicate determines whether an iron ore has a mining value and is an important basis for selecting the most effective beneficiation process and determining the best beneficiation index. Determination of iron silicate iron in the past chemical separation, heavy liquid separation, selective reduction, selective oxidation and so on. More commonly used is to select the reduction method, that is 600 ° C hydrogen reduction method. The main disadvantage of the law is that certain iron silicates, such as chlorite,
