Copper Removal from Molybdenite by Sulfidation-Leaching Process

This paper is concerned with a novel process of chemical purification of molybdenite concentrates containing chalcopyrite as the main copper impurity. The process involves The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the Mineralogical Prediction on the Flotation Behavior of

Recovery of molybdenum from roasted copper slags

In this regard, copper slags were treated using roasting–leaching process in order to recover the molybdenum content in the slag. Oxidative roasting is used to The molybdenum mining industry discharges a large volume of acidic wastewater containing significant amounts of molybdenum, copper, and other non-valuable metals. In this study, the separation of metal ions (Mo 6+,Fe 2+,Ca 2+,Na + ) and recovery of sulfuric acid from molybdenum metallurgical wastewater were investigated Acid recovery from molybdenum metallurgical wastewater via

Process mineralogy as a key factor affecting the flotation kinetics

The aim of this study is to apply process mineralogy as a practical tool for further understanding and predicting the flotation kinetics of the copper sulfide minerals. The minerals’ composition and association, grain distribution, and liberation within the ore samples were analyzed in the feed, concentrate, and the tailings of the flotation The process involves a sulfidation of the molybdenum concentrate with 82 (g) at 380 °C followed by a leaching stage. H 2 SO 4 -NaCl-O 2 leaching of a sulfidized concentrate containing 3.4% Cu for 90 min at 100°C produced a molybdenite concentrate with less than 0.2% Cu, which is appropriate for marketing.

Molybdenum alloying in cast iron and steel Advances in

Molybdenum additions less than about 1.0% have been found insufficient to suppress the formation of pearlite in heavy section castings, while amounts greater than 3.0% have no additional benefit in that respect. Molybdenum, if alloyed in conjunction with nickel, copper and manganese enhances the ability of suppressing The need for copper and molybdenum continues to grow as does the need for clean efficient metallurgical technologies capable of treating mixed metal concentrates. Currently, the use of hydrometallurgical pressure oxidation for copper concentrate treatment is growing.NSC Hydrometallurgical Pressure Oxidation of Combined Copper

Comprehensive Electrochemical-Chemical Study of Copper

Molybdenite is the most important molybdenum concentrate, which is mainly recovered as a by-product from porphyry copper deposits. Due to the low efficiency of purification processes such as flotation in the reduction of copper content of molybdenum concentrate to a standard level (i.e., less than 0.5 wt.%), further There are other key nonferrous metal enterprises such as China National Gold Group, China Nonferrous Metal Mining, China Minmetals.
