一、前言: 黃铁矿为与方鉛矿伴生的矿物之一,有的地区其成分高达90%以上,为制硫酸的主要原料。測定其成分属于物相分析范圍,而有关分析資料在国內尚未見发表。笔者曾根据有色金属矿石分析中譯本第四分册115頁的方法进行黄铁矿中硫的測定以計算FeS_2含量,发現此法有二缺点: 1.重量法定硫操作較长,在进行大批生产分析时不能达到多、快、好、省的目的;
I. Foreword: Pyrite is one of the minerals associated with galena. In some areas, its composition is as high as 90% or more, and is the main raw material for sulfuric acid production. Determination of the composition of the phase analysis of the scope of the analysis of the data in the country has not yet been published. The author has based on non-ferrous metal ore analysis of the fourth volume of translation of the 115th page method for determination of sulfur in pyrite to calculate the FeS_2 content and found that this method has two shortcomings: 1. The weight of the legal sulfur operation longer in the mass production Analysis can not achieve more, faster, better, the purpose of the province;
