US4083921A - Purifying molybdenum flotation

Copper, iron, and lead impurities are removed from molybdenum flotation concentrates by mixing the feed concentrates with a nonvolatile chloride salt, heating the mixture to a temperature of from about 200 to 350 C for a time sufficient to activate the lead impurities in the concentrates so that they can be leached therefrom during the subsequent leach step, and leaching copper, iron, and

molybdenum, the appropriate concentrate was obtained by this process with hydrometallurgical method. It was also determined that the trace amounts of Ta, Nb and V in ore were collected in the concentrate phase. In the first step of flotation, the fluorite left in the tailing contained 29.6 % of CaF2. After

Optimization of a Copper/Molybdenum Flotation

A study to determine methods to hinder the flotation of pyrite, other than the specific use of lime, in rougher flotation was conducted. Specifically, the goal was to ... molybdenum include aircraft parts, some missiles, and the nuclear power industry. Compared to base and precious metals, molybdenum usage is minor with maximum

Mineralogical Prediction on the Flotation Behavior of

It was shown that a simple mineralogical prediction based on the R max and k of each copper and molybdenum minerals in the various Cu–Mo ores, the blending ratio of each Cu–Mo ore, total Cu or Mo and the mineral composition of the feed ore can be used to estimate the flotation recovery of blended Cu–Mo ore. This estimation method might be

Selective flotation separation of molybdenite and

Selective flotation separation of molybdenite and

Dec 20, 2019 Based on the thermal pretreatment method, the flotation separation of molybdenite and chalcopyrite was realized for both mixed binary minerals and Cu-Mo bulk concentrates without addition of depressant. The XPS analysis results showed that the oxidation degree of chalcopyrite was much higher than that of molybdenite

Selective flotation of chalcopyrite and molybdenite using

Jun 15, 2018 Hydrogen peroxide (H 2 O 2) has been used as an oxidizing agent in the selective flotation of chalcopyrite and molybdenite.However, this method required relatively high concentration of H 2 O 2 to deliver flotation results (i.e., mineral grades and recoveries) comparable to those obtained by the conventional copper-molybdenum (Cu-Mo) ores flotation using sodium hydrosulfide (NaHS)

Molybdenum Processing - IMOA

The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide

Therefore, the flotation method was applied. Molybdenum usually occurs as molybdenite in nature and enrichment of molybdenum is much easier in comparison to other ores with high yield. Molybdenum has different constituent in minerals.Therefore, it was determined that flotation yields are low. Moreover, recovery of concentrate of molybdenum and
