technical field

Background technique

At present, there are a large number of open-pit magnetite mines abroad such as Africa, Brazil, Australia and other places, and a considerable part of the ore iron grades in these magnetite mines are between 40% and 50%. For these open-pit magnetite mines, it is generally necessary to dry the ore to throw out the gangue contained in the ore and the surrounding rock mixed in the mining, so that the grade can reach 58%-62% for sale.

However, magnetite with a grade between 40% and 50% is generally dry-selected directly after coarse or medium crushing. Due to the large size of coarse and medium crushing products, many large ores are ores and The conjoined body of gangue, if this part of the ore enters the waste rock, it will reduce the recovery rate of the final concentrate, and if it enters the ore, it will reduce the grade of the recent concentrate.
