Iron Grade

The copper-iron ore has grades of 0.58% Cu and 42.14% Fe in Anhui. According to test on raw ore, it has the characteristics of close intergrowth and fine dissemination size, which belongs to a refractory ore. The copper oxide distributes mainly at the perimeter of copper sulfide. According to the characteristics of the structure, a flow sheet of rough grinding and flotation of inter-locked particles is taken. This process can recover copper effectively, leading to the recovery of Cu increase to 70.05%.A combined technological process of high intensity magnetic separation-gravity separation is used to hematite, which achieves an iron grade of 62.34% in the final concentrate and a recovery of 65.49%.

The average grade of iron ores in China is around 32%, about 10% lower than the world’s average level. In order to alleviate the demand of iron ore for steelmaking industries, it is urgent to develop a highly efficient, energy-saving, low-carbon and environment-friendly technology. The goethite ore from Northern Hainan Island was studied via reduction magnetization by pine, rice chaff, and corn straw biomass fuels. The magnetic properties and magnetic separation were discussed by optimizing the parameters of roasting temperature, roasting time, and the ratio of biomass fuels. The results show that we could obtain concentrated iron ore grade of pine roasting and magnetic separation grade of iron concentrate 61.64% with the recovery of 79.75% via pine fuel roasting, 61.75% with the recovery 80.16% via rice chaff, and 61.47% with the recovery of 81.28% via corn straw roasting. Thereby, we could deduce that biomass fuels for reduction roasting of low goethite ore is promising to substitute the traditional coal and coke fossil fuels.

Iron ore minerals are mainly silicate-type iron minerals in raw ore, and its distribution rate was 51.93%; followed by magnetic iron, and its distribution rate was 36.81%; content and distribution rate of other minerals was very low; element grade of iron, phosphorus, sulfur, silica were 11.90%, 0.043%, 0.013% and 45.23%, the main gangue were silica and calcium oxide, recyclable iron minerals mainly is magnetic iron mineral. Due to the grade of iron of raw ore and the amounts of optional magnetite was relatively little, in order to investigate the optional of low-grade ore, weak magnetic separation test and weak magnetic separation tailings-strong magnetic separation test were put into effect.

Large amount of sourrounding rocks in Jianshui China has been discarded for many years, and the “rock” is characterized by Cu-Fe polymetallic constituents and of low grade. According to the results of chemical and phase analysis as well as the mineralogy, a joint pocess of flotation and magnetic separation was proposed and used to process the ore. Flotation results show that the combined processing technology is efficient in utilizing the low grade rocks. A copper concentrate assaying 20.68% Cu at the recovery of 80.11% can be obtained, when the raw material assays 0.79% Cu.
