Study on Flotation of Copper Molybdenumt and Mechanism Under the Low ...
Oct 25, 2020In order to explore the influence of pulp potential on flotation of copper molybdenum ore, chalcopyrite and molybdenite were used as samples to study the effects of pulp pH, flotation reagent type and consumption on pulp potential. The results show that the optimum slurry potential is 360 mV and pH is 8. When sodium sulfide, ammonium sulfate and sodium carbonate are mixed in 1:1:1 ...احصل على السعرWhatsApp

Molybdenum processing. The mined ore is first crushed with ball or rod mills and then ground to very fine particles. The next step is flotation, where the ground ore is mixed with a liquid and aerated. The resulting molybdenite concentrate contains between 85% and 92 % MoS2 and is subsequently roasted at temperatures between 500 and 650 °C.احصل على السعرWhatsApp
