The agglomeration method includes three processes of sintering, pelletizing, and ball pressing. At present, the sintering method is mostly used in China. Only when the manganese concentrate or fine ore is very fine, and the -200 mesh is more than 80% and the product is not allowed to contain residual carbon, the pellet or the compact is used.

In the early 1950s, China's manganese ore fines were mostly sintered by sintering and soil sintering. With the development of steel production, indigenous sintering not meet the requirements, and thus have started construction of efficient sintering machine or other agglomeration equipment. In 1970, China's first powder manganese ore sintering machine (18m 2 ) was completed and put into operation in Xiangtan Manganese Mine. In 1972, Jiangxi Xinyu Iron and Steel Plant built two sets of 24m 2 sintering machines. In 1977, China's first manganese concentrate pelletizing equipment was 80m. 2 belt roasting machine was completed and put into operation in Zunyi manganese mine. In the 1980s, Polianite, August manganese, Xiangxiang ferroalloy plant have been built 18 ~ 24m 2 sintering machine multiple, Shanghai Ferroalloy Plant introduction apparatus used as a pressure ball briquetting fine ore.
The development of agglomeration technology brings greater economic benefits to the smelting of manganese alloys. Taking Jiangxi Xinyu Iron and Steel Plant as an example, increasing the ratio of clinker in the furnace and replacing the hot sinter with cold-burned ore can greatly improve the technical indicators of blast furnace smelting (see table below).
