Developments in phosphate-rock beneficiation and the problems with Indian phosphorites Ch. Rambabu and K. K. Majumdar Introduction Phosphate-rock or more precisely the phosphorites form the repository of phosphate supply for the fertilizer industry for manufacture of elemental phosphorus, phosphoric acid and innumerable alkali phosphates.
After stripping the overburden, the phosphate ore is stripped by dozers and transported by tracks, belts or water carrying to the beneficiation area. Apatite is the main mineral of phosphate ore. The apatite group includes Fluorapatite, Chlorapatite, and Hydroxyapatite. But, the major mineral, especially in sedimentary phosphate rock is ...
In this paper we present the development of the SysML model of a process plant of phosphate the beneficiation activity of phosphate. The model includes the requirements as well as the structure, behaviour and activity diagrams. In this work a model transformation from SysML to a process simulation language in this case Excel is presented.
