This approach is ac-tualized in the final concentration cycle of dressing of Erdenet copper–molybdenum ore (Mongolia). The technology of produc-tion of quality marketable copper, molybdenum and pyrite concen-trates has been developed. Key words: copper–molybdenum ore, flotation tailings, final concentration circuit, flotation, quality ...

Molybdenum metallurgy is the technology for extracting metal molybdenum from molybdenum-containing ore raw materials. The molybdenite (MoS2) has been used …

The phase analysis results show that the 95.83% of molybdenum is sulfide ore and with 4.17% oxide ore. The major metallic minerals are molybdenite, pyrite, sphalerite, chalcopyrite and galena. ... treatment and utilization of copper and molybdenum ores are of great significance to the development of economy and technology in the …

Flowsheet of copper–molybdenum ore beneficiation using a combined flotation and biohydrometallurgical method. Flotation was performed at a relatively high рН levels (10.2–10.5) exceeding the рН value in control experiments, without the application of bioleaching technology (9.8–10.1).

The main mineral of molybdenum is mo-lybdenite −0.012%. Sulfide minerals of pyrite are present in amounts up to 0.5%. According to the X-ray phase analysis, the content of the rock-forming ...

The existing molybdenum ore grade determination methods lag behind the beneficiation work. Therefore, this paper proposes a method based on a combination of Visible-infrared spectroscopy and machine learning to rapidly determine molybdenum ore grade. Firstly, 128 molybdenum ores were collected as spectral test samples to obtain …

The technology of molybdenum extraction from molybdenite concentrate by using sodium chlorate has been investigated. The results show that leaching time, liquid-to-solid ratio, leaching temperature, agitation speed, sodium chlorate and hydrochloric acid concentration have significant effect; optimum process operating parameters were …
