Abstract

The weak magnetic iron ore selection process starts with the crushing of iron ore with iron content less than 35%, selecting high ladder magnetic strong interference selecting the grains, removing large quantity of adjacent formation, dike rock, grinding the iron grain and powder using ball grinder to original mineral serum, through wet strong magnetic machine for selection and accumulation and fine selection with filtering of water. It is less in process energy consumption, good in energy reservation effect, good in production benefit, convenient, being a pioneering way for iron ore selection.

Description

Technical field:

[0001] The invention is a new beneficiation process of weak magnetic iron ore, which relates to the technical field of iron ore beneficiation process. Background technique:

[0002] The existing iron ore beneficiation process is for magnetite ore with strong magnetism, not suitable for weak magnetic iron ore. There has been no good method for beneficiation of weak magnetic iron ore with less iron content, resulting in A large amount of weakly magnetic iron ore cannot be utilized, and even in some areas, it is abused as industrial stone at a low price, which causes a great waste of resources. In the 1980s and 1990s, smelting and roasting techniques were used in an attempt to reduce the weakly magnetic iron ore containing ferric oxide to magnetic iron ore of ferric oxide, but due to high energy consumption, Due to high investment, low yield, poor benefit and lack of practicability, this process cannot be promoted and used, and it is forced to stop. With the ...
