The market price of this kind of iron ore is $100 per tonne, so the ore cost is about $166.7 per tonne of iron. The price of hydrogen obtained by different processes varies greatly. Considering that more and more attention has been paid to the future use of hydrogen metallurgy, the cost of hydrogen used in industry will be lower and lower.
Figure (PageIndex{2}): Three Common Ores. (left) Iron ore, (middle) Manganese ore – psilomelane, and (right) Lead ore – galena and anglesite. Most metals are found as types of rock in the Earth's crust. These ores contain sufficient minerals with important elements including metals that can be economically extracted from the rock.
Manganese was extracted from leaching low-grade manganese ore in sulfuric acid medium. The effects of granule diameter, leaching time, liquid/solid ratio (V/W) and the concentration of sulfuric acid were investigated through orthogonal and single factor experiments. The experimental results showed that the optimal leaching conditions are, …
