Air is pumped into each cell, the solution being agitated to bring froth of bubbles to the surface. In the case of copper minerals, the particles adhere to this froth ...

Copper–molybdenum ores flotation in sea water: Floatability and ...

WebThe copper recovery is by standard flotation reagents identified in the description of the copper mineral flotation. The naturally float molybdenum with copper but can be congested in the foam by the mineralization of copper and molybdenum collector use (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) improves its buoyancy. WebThe moly flotation circuit has similar groups of flotation cells with chemicals to float the moly concentrate and settle out the copper concentrate. Here, 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 separates molybdenite ... how do you unhighlight something in adobe pro

Copper Flotation - Mineral Processing & Metallurgy

WebOct 1, 2012 · There are several flow sheets (listed in Fig. 1a and b) used in the flotation recovery of copper and molybdenum from their porphyry sulfide ores. Fig. 1a is a typical flow sheet that consists of two stages (Raghavan and Hsu, 1984, Bulatovic, 2007, Liu et al., 2011). The first stage, commonly known as the copper circuit, produces a bulk copper ... Webcopper selectivity is typically in the 9-11 pH range, use of a moly collector in bulk flotation can improve floatability. Some mines find that the moly collectors can have a negative impact on copper flotation so testing and evaluation must be conducted to find the optimum moly collector hydrocarbon and frother products. WebNaHS is used to depress copper and iron sulfides in the copper/moly flotation circuit. NaHS is also used as a sulfidizing agent to treat oxide ores. NaHS is used in the Kraft process (pulp & paper), the tanning industry, the specialty chemicals and reforming industry, dyes, mining, home care products, and personal care products.
