Laboratory rougher flotation tests were conducted with two samples of CuMo ores in fresh water and in sea water as a function of pH. In both cases Cu recoveries were slightly lower in sea water than in fresh water for a wide range of pH . Flotation of molybdenite was however strongly depressed in sea water at pH higher than 9.5.
Flowsheet. Feed to the molybdenum flotation circuit is a bulk concentrate of 27% Cu and 0.9% Mo at 55 to 60% 325 mesh produced with the use of sodium isopropyl xanthate, fuel oil, aeroprotnoter 3302, and frother MF 142. Sodium hydrosulphide and fuel oil are stage added throughout the roughers and first cleaners.
The flotation tests on single minerals and molybdenum bearing copper concentrate were carried out using a model XGF 1600 flotation machine operating at 1600 rpm with a 30 mL suspension cell. In a typical test, the mineral slurry was prepared by adding 2 g of a single mineral or molybdenum bearing copper concentrate to 30 mL of distilled water.
Henry E. Wood of Denver had developed his flotation process along the same lines in 1907, patented 1911, with some success on molybdenum ores. For the most part, however, these were isolated attempts without fanfare for what can only be called marginal successes.
determined as 5.56.5 in molybdenum flotation, while molybdenite might be depressed at high pH due to calcium ions. Besides, the ferrous and ferric species at higher pH values caused depression of molybdenite too . In this study, the determination of the flotation behavior of a molybdenum ore was
The Molybdenum Process Flowsheet Grinding. The Vibrating Screen removes fines ahead of the Rod Ball Mill. This Mill is arranged with... Coarse Flotation Circuit. On many molybdenum ores a high grade concentrate can be made in this four cell coarse... Regrind Circuit. This consists of a ...
The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a froth. Air is pumped into each cell, the solution being agitated to bring froth of bubbles to the surface.
