Abstract

Iron ore is an important strategic import resource in China. Australia is the largest source of iron ore in China, with over 700 million tons of iron ore imported annually. With the increase of imports, the water content of iron ore from Australia is abnormal, generally about 8%, but in recent years, iron ore with water content higher than 10% has been repeatedly found in iron ore imported from Ningbo Port. There is even iron ore with a water content of up to 15%. Iron ore with high water content not only increases the transportation cost, but also affects the shipping safety and causes the hidden loss of iron ore tons. This paper takes 7.6% imported iron ore from Australia and 15% Australian iron ore with water content as the research object for comparative analysis. DTA method is used to analyze two kinds of iron ore with different water content to determine the water content and storage mode. The phase structure and composition of iron ore with different water content were tested by XRD. The micromorphology and micropore structure of iron ore with different water content were analyzed by SEM and the element distribution and content of iron ore with different water content were analyzed by EDS. Finally, the porosity of iron ore with different water content was tested by BET and BJH methods. Through comparative experiments, the characteristics and formation mechanism of water content of high Australian iron ore are analyzed from different angles, so that relevant technicians can grasp the formation mechanism of high water content Australian iron ore from the technical point of view, and effectively avoid hidden loss tons.
