The process flow diagram is an essential part of chemical engineering. It conveys a process and the path of its individual components - therefore, it is essential to learn how to read and create one. The process flow diagram is divided into three sections: process topology, stream information, and equipment information.
What is Process Flow Diagram? A Process Flow Diagram is a graphical tool depicting the steps of a process in a serial order. The intrinsic reason behind it is to include all of the steps that are critical to the process. Flow diagrams are used by the team to visualize the process, and often annotate it with performance information.
Hence, developing a novel process with low energy consumption becomes a hot topic in the production of ferronickel with laterite. A few researchers [5, 12, 13] have attempted to produce higher grade ferronickel concentrate by magnetic separation after pre-reduction in a rotary kiln. Nevertheless, to avoid forming a ring against the wall of the ...

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into …
