緒言找尋鉻礦是目前我國地質工作者之主要任務。因此研究一個適合於快速分析而且有足够準確度的鉻礦中鉻的分析法是有其意義的。文献上有關分析铬的方法很多,但是均需经過熔融的手續。近年來又有文献推薦了用磷酸或磷硫酸來分解鉻礦。而在蘇聯的最近文献上,烏沙欽科又推薦了用燒結法來分解鉻礦。因此更仔細的來研究一下鉻礦的分解方法和測定條件是有必要的。本文主要是研究了酸溶礦時测定鉻的一些條件,並對鉻礦的燒結分解作了一些改進。
Introduction Chromium ore is currently the main task of geological workers in our country. Therefore, it is meaningful to study a method for the analysis of chromium in chrome ore, which is suitable for rapid analysis and with sufficient accuracy. There are many ways to analyze chrome in the literature, but both require melting procedures. In recent years, there are literature recommendations using phosphoric acid or phosphoric acid to decompose chromium ore. In the recent literature of the Soviet Union, Ushachenko also recommended the use of sintering method to decompose chromium ore. Therefore, a more careful study of chromium ore decomposition methods and determination of conditions is necessary. In this paper, some conditions for the determination of chromium in acid-dissolved ore are studied, and some improvements are made in the sintering decomposition of chromium ore.
