I believe we all know a little bit about iron sulfide, it is suitable for titanium dioxide manufacturing industry, it can make the titanium dioxide precipitation, precipitation of water, can enhance the whiteness of titanium dioxide. Today, iron sulfide manufacturers to bring the notes on the synthesis methods of iron sulfide are matters for your attention:
Underground mining method with the majority of small and medium iron sulfide mines, sublevel caving mining method is the main. Open pit mining method for shallow mines with few shallow deposits. The general process flow and general process flow of pit mining are the same as "phosphorite rock". Beneficiation methods mainly include flotation, gravity separation and magnetic separation method. General beneficiation process with the "phosphorus block rock". For a single, multi metal pyrite and pyrite containing carbon less coal pyrite by grinding classification and flotation process; for carbonaceous clay and more coal pyrite flotation or by gravity separation flotation gravity flow. More than 85% of the iron sulfide ore used in the manufacture of sulfuric acid, the refined sulfur. When the elements such as Cu, Pb, Zn, Ag, Au, CO and Ni in pyrite reach certain content, the pyrite can be recycled comprehensively.
Tongling Fukang tips must pay attention to the matters of FES oh!
Ferrous sulfide ignition is very low, usually at about 50 degrees in the above can be spontaneous. In the oil refining tower inner surface and inner filler will produce ferrous sulfide, in the shutdown maintenance process, equipment and packing contact with oxygen, light and make the temperature rise, it is easy to cause spontaneous combustion. This production before the accident often happen, so usually regularly to water tower equipment idle sulfide, ferrous sulfide wholesale manufacturers tell you the synthesis method of iron sulfide is the reason.

We are not unfamiliar, FES, Tongling Fukang small in here with you simply say is mainly used under FES with which industry 1 producing hydrogen sulfide; 2 for paper mill with 3 fiber softening; smelting casting; 4 titanium dioxide additives; 5 used for purifying wastewater containing heavy metals. 6 for sulfur alloy wire, said above the industry according to the story is the most widely used in industry, ferrous sulfide manufacturers now Xiaobian take you further understand its determination steps, you will want to know!
Method for determination of ferrous sulfide slag based on various leaching metal hasp residues, selective dissolution of FeS with bromine methanol solution, iron oxide remained in the residue; also available bromine methanol solution with the leaching of iron and FeS, determination of content of two iron, then subtract the metallic iron content of iron content by FeS the. Analysis steps: take 0.2000g sample in the conical bottle, add 30mL bromine methanol solution (595), from time to time shaking leaching 60min. After filtration, washing and filtrate treatment, iron and FeS content were obtained.
The above content is Xiaobian to introduce you to the FES, I believe you will understand a lot, do you have any questions please feel free to contact us, we are always waiting for.
Read the "FES wholesale manufacturers tell you the steps of" determination of ferrous sulfide synthesis method of iron sulfide, we believe that for FES wholesale manufacturers tell you the synthesis methods of iron sulfide have probably understood the problem, if you want to know the Anhui iron sulfide, manufacturers, wholesale, sales and other related content, please pay attention to the follow-up of our news!
