Abstract

The invention relates to a suspension roasting manganese and iron treatment method of iron-contained manganese ore, and belongs to the technical field of mineral processing. The method includes the following steps that (1) the iron-contained manganese ore is crushed to be subject to ore grinding; (2) first-section low-intensity magnetic separation is carried out; (3) first-section low-intensity magnetic separation gangue is placed into a roasting furnace, gas and air are led in, and the first-section low-intensity magnetic separation gangue is subject to oxidizing roasting; (4) a reduction roasting furnace is adopted, and oxidization powder ore is placed into the reduction roasting furnace to be subject to reduction roasting; (5) roasted ore is subject to second-section low-intensity magnetic separation; and (6) first-section low-intensity magnetic concentrate and second-section low-intensity magnetic concentrate are merged to serve as an iron ore concentrate finished product. The suspension roasting manganese and iron treatment method is simple in technological process, large in equipment treatment amount, easy in product character control, capable of achieving industrialized application, capable of achieving energy conservation and environmental protection and capable of easily achieving large scale.

Description

technical field

[0001] The invention belongs to the technical field of mineral processing, in particular to a method for separating ferromanganese by suspending roasting ferromanganese ore. Background technique

[0002] my country's high-quality manganese ore and iron ore resources are increasingly scarce due to the huge consumption of the iron and steel industry. However, there are a large number of ferromanganese ore resources with high iron content in my country, which have not been effectively utilized on a large scale. The manganese minerals in the ferromanganese ore resources are mainly rhodochrosite and pyrolusite, and the iron minerals are mainly hematite, goethite, and limonite. , Siderite, etc., to realize the effective utilization of iron and manganese resources in ferromanganese ores is of great significance to alleviate the shortage of self-produced iron and manganese resources in my country.
