The first step to understanding the answer to this question is to understand what pyrite is and what is made up of. Pyrite (aka "fool's gold" or "iron pyrite") is a metallic looking material with numerous applications. Its chemical formula is FeS 2, meaning that it is a compound made up of iron (Fe) and Sulphur (S).
The invention relates to the technical field of comprehensive recycling of pyrite tailings, and particularly provides a process for recovering kaolin, sulfur concentrate and titanium concentrate from pyrite tailings, which comprises the following steps: s1 grinding and pulping: preparing fine-grained pyrite tailing sand with the granularity of-0.074 mm, and …
In the field, pyrite in veins or in massive replacement bodies weathers and forms a limonitic capping i.e. a gossan (Blanchard Citation 1968). Limonite is a general field term for a mix of haematite (Fe 2 O 3 …
