The Asinawa iron ore is located about 3km to the southeast of Penjween town, Sulaimaniya Governorate, Kurdistan Region, Northeastern Iraq near the Iraq-Iran border. The exposed iron ore deposit is about 60 and 400m wide and long respectively. The present study is the re-study of the geology and geochemistry of the Asnawan Iron ore deposit  and concluded that the country rocks are consist of ...

Dilution can best be defined as the proportion of waste tonnage to the total weight of ore and waste in each block. Predicting the internal dilution based on geological boundaries of waste and ore in each block can help engineers to develop more reliable long-term planning designs in mining activities. This paper presents a method to calculate the geological internal dilution in each block and ...

There is a rapidly increasing demand for iron resources with the fast-paced development of the iron and steel industry. For this reason, the iron and steel industry is facing the risk of a raw material shortage. Deposits of high-phosphorus iron ores are widely spread worldwide, but the use of these deposits in industry is limited owing to the high phosphorus content, which affects the cost of t...

A study on the quantitative leaching of iron ore in hydrochloric acid solution has been undertaken. The elemental composition of the iron ore was also carried out using ICP-MS technique. The major elements in the iron ore include: Fe(66.7%); Al (0.2%); Si (5.2%); Ti (0.02%) and O (28.0%). Some traces of V, Ni, Zn, Ce, Cr, La, Y and Zr were also found. The effects of contact time, acid concentra...

Iron is one of the most important strategic materials in national production, and demand for iron ore huge world. High quality reserves have been almost exhausted, it necessary to develop a technology that utilizes low-grade ore. Limonite representative due its complex mineral elemental composition. In this paper, union process was employed separate elements limonite. Firstly, rough concentrate...

Biomass was used as reducing agent to roast the Baotou low-grade limonite in a high temperature vacuum atmosphere furnace. The effect of calcination temperature, time and ratio of reducing agent on the magnetic properties of calcined ore was studied by VSM. The phase and microstructure changes of limonite before and after calcination were analyzed by XRD and SEM. The results show that in the ro...
