Unit operations
Unit operations consist of drawing procedures to operate plant, optimize
them, making P&IDs, setting them, calculating reactions and their
sequences, and calculating efficiencies and throughput.
Piping and Instrumentation Diagrams (P&IDs)
Piping and Instrumentation Diagrams (P&IDs) for rare earths. For a
typical 5 ton / day plant, example optimized P&IDs are developed.
Example P&IDs for Au processing plants are shown here [20].
