1. Introduction. Molybdenum (Mo) is an important raw material in many industrial fields, which is often used in lighting, pigments, medical production, material forming, and so forth [1], [2].Since Mo is a cofactor in many enzymes, it is also an essential micronutrient for all living organisms [3].However, excessive consumption of Mo can …

With the vigorously growing demand of the steel industry, oil and gas industry, corrosion resistance alloys, cast iron, and catalyst industries, high-grade molybdenum ores are being exhausted gradually in the world. Thus, much attention have been drawn to the recovery of molybdenum from low-grade molybdenum ores in recent years.
A water cooled slag of 0.2 wt% Mo was used as sample. Mo concentration in slag was controlled from 0.2 to 4 wt% by adding MoO3 reagent, heated at 1300 °C for 1 hour in Ar atmosphere by super ...
