PRESSURE LEACHED OXIDE (PLO). A MOLYBDENUM TRIOXIDE POWDER PRODUCED B Y AN AUTOCLAVING PROXCESS WITH PURITY BETWEEN 95 AND 98%.. PLO IS A SUBDTITUTE FOR ROASTED MOLYBDENUM CONCENTRATES, WHICH ARE USED, AMONG OTHER THINGS AS A FEEDSTOCK FOR THE PREODUCTION OF HIGHER PURITY MOLYBDENUM PRODUCTS (ABOVE 98% PURITY) . PLO IS NOT INTENDED TO BE USED AS A SUBSTITUTE FOR HIGHER PURITY MOLYBDENUM PRODUCTS. THE PROCESS TO PRODUCE PLO INVOLVES CONCENTRATING A MOLYBDENUM DISULFIIDE CONTAINING ORE BY FLOTATION TECHNIQUES TO PRODUCE AN UNROASTED MOLYBDENUM DISULFIDE CONCENTRATE WHICH IS THEN PROCESSED VIA THE PLO PROCESS, A HYDROMETALLURGICAL TECHNIQUE INVOLVING AUTOCLAVING UNDER PRESSURE, SETTLING, WASHING AND DRYING TO PRODUCE A TRANSPORTABLE POWDER. THE PLO PRODUCT IS COMPARABLE TO AUTOCLAVE MOLYBDENUM. PRESSURE LEACHED OXIDE (PLO) IS GOING TO BE USED AS A SUBSTITUTE FOR ROASTED MOLYBDENUM CONCENTRATE (RMC).AND CAN BE USED FOR THE PRODUCTION OF OTHER MOLYBDENUM PRODUCTS OR FOR METALLURGICAL PROCESSES.

AUTOCLAVE MOLYBDENUM CONCENTRATE (AMC). A MOLYBDENUM TRIOXIDE POWDER OF A PURITY NOT EXCEEDING 99% FOR USED IN THE METALLURGICAL INDUSTRY , SPECIFICALLY IN THE STEEL INDUSTRY AS A WAY OF INTRODUCING THE METAL MOLYBDENUM INTO STEEL. THE PROCESS TO PRODUCE THE MOLYBDENUM CONCENTRATE INVOLVES CONCENTRATING A PORPHYRY COPPER ORE DEPOSIT BY FROTH FLOTATION TO PRODUCE MOLYBDENUM DISULPHIDE. THE MOLYBDENUM DISULPHIDE IS THEN SUBJECTED TO THE MOLYBDENUM AUTOCLAVE PROCESS (MAP), WHICH IS A HYDROMETALLURGICAL PROCESS INVOLVING OXIDATION, SOLUTION PURIFICATION, CRYSTALLISATION , AND CALCINATION .
