Pyrite Flotation Process Iron Ore

Pyrite flotation in air and nitrogen Tests on the two ores showed that nitrogen can, under certain conditions, promote the flotation of pyrite' Figs. 1 and 2 illustrate this (with recovery vs flotation residence time) for Brunswick Mining ore Fig. 3 shows the results on ore from Mattabi.

    Abstract in this study the flotation of pyrite as the main sulfide impurity of Sangan iron ore in Iran, was investigated. For this purpose the effect of collector type, pH, collector concentration and stage dosing on reverse flotation of iron sulfide ore from magnetite ore was investigated. Two type of.Process III is to treat the ore with flotation first. The flotation concentrates then going to be roasted, and then go to cyanidation. The characteristic of this process is that the pyrite concentrate is roasted to remove arsenic, antimony and other substances before entering the cyanidation operation, thus improving the leaching effect.

    In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced and smelted in an electric furnace.The grain size of pyrite is suitable for removal by flotation, so although the iron ore has a high sulfur, it can be seen from the analysis results of process mineralogy that it is easy to get low sulfur iron concentrate. 3.4.
