Description. It is in the laundering or cleaning banks where the present polyoxyethylene glycol esters are utilized to suppress . In the subsequent molybdenum flotation steps sufficient copper depressants may be utilized such as alkali sulfides, cyanides, cuprocyanides, ferrocyanides, or ferricyanides.
base metals. Base metals, such as copper, molybdenum, zinc, lead and nickel, constitute the back bone of our society. For without these base metals, we would be without the commodities we take for granted everyday such as electricity, heat, mobile phones, steel/stainless steel, batteries, paints, coatings, inks and rubber.

Molybdenum produced as a byproduct of copper from copper porphyry deposits, like the Bingham Canyon deposit in Utah, is removed as molybdenum disulfate during flotation of the powder copper ore. The concentrate is roasted to make molybdic oxide, which can be put through the same sublimation process to produce molybdenum metal.
A method for the recovery of molybdenum from an ore that includes a molybdenumbearing mineral, such as molybdenite. The ore is treated to recover metal values from the ore, such as base metals, by utilizing a depressant to depress the flotation of the molybdenite. The tailings, which can include insoluble silicate minerals in addition to the molybdenite, are then activated to render the ...
