According to the technical and economic calculation data compiled by the ferrous metallurgical design institute for most iron deposits in the former Soviet Union and the actual production data of each mining company, the classification of Soviet iron meteorites is shown in Figure 2. The ore iron grade is marked on the abscissa axis, and the ore metallurgical value index including the mining cost is indicated on the ordinate axis. The dashed line indicates the possible distribution of the hypothetical iron grade ore that does not belong to any deposit. The intersection of the curve and the abscissa axis is the iron grade value of the tailings, which indicates that the ore with such iron grade has a metallurgical value of zero. Based on the relationship obtained, the minimum industrial iron grade of the ore can be determined. The lowest industrial iron grade value is the intersection of the curve with a metallurgical value equal to one. Metallurgical values ​​can be compared for various types of ore under the same iron grade conditions. Under the condition that the iron grade is 30%, according to the comparison, the ore can be arranged in the following order: We are a factory with research and development design, production and sales of machines, we have a professional team, able to provide professional training and after sales guidance, we have the complete equipments like silicone Vacuum Machine, silicone oven, Silicone Dispensing Machine, gum machine, silicone cutting machine, hydraulci machine, we are looking forward to your cooperation.

Ore type metallurgical value of ore Mп
Titanium magnetite 1.95~2.1
Magnet quartzite 1.2~1.6
Magnetite 1.2~1.4
Magnesia magnetite 1.05~1.25
Limonite 1.05~1.2
Magnet - Hematite 1.0~1.2
The highest value of the metallurgical value of titanium magnetite ore is closely related to the lax recovery of vanadium from concentrates, which significantly reduces the cost of metallurgical processing by selling vanadium by-products.
When mining, building blocks and metallurgical processing costs unchanged, proportional to the value of indicators and metallurgical beneficiation costs. These costs are calculated taking into account the complexity of the beneficiation process and method, the size of the grinding and the resulting tailings from the process due to the need to further regrind, classify, sort and transport at a coarser particle size. Cost changes.
