May 05, 2016 The usual flotation reagents are the xanthates and a selective frother such as Dowfroth 250 or one of the light alcohol type frothers. The flotation steps usually consist of roughing, scavenging, cleaning and recleaning to provide a high grade copper concentrate which contains the bulk of the contained molybdenite
Get PriceThe invention discloses a flotation separation method for molybdenite and galena, which comprises the following steps of: 1, rough grinding; 2, rough selection and scavenging for obtaining
Get PriceThis stage in bulk flotation of copper-molybdenum and usual reagents are utilized. According to Paul Ramdohr (1980, The Ore Minerals and Their Intergrowths, Page 878) Jordisite is MoS2 amorphous to X-Rays, which occurs in semi metallic masses of anthracitic aspect in low temperature deposits; e.g. Bleiberg in Carinthia, and forms there the base
Get PriceThe flotation method is edno-molybdenum ore, including grinding ore and collective flotation of copper and molybdenum in alkaline environment, created lime, characterized in that the collective flotation is carried out in the presence of the collector Aero-MX 3601 and the expander, then the bulk flotation concentrate after evaporation and desorption heated slurry to 40-60 With live steam in the presence of sodium sulphide sent for molybdenum flotation
Get Pricemolybdenum, the appropriate concentrate was obtained by this process with hydrometallurgical method. It was also determined that the trace amounts of Ta, Nb and V in ore were collected in the concentrate phase. In the first step of flotation, the fluorite left in the tailing contained 29.6 % of CaF2. After
Get PriceThe objective of this study is to provide a simple method based on mineralogical analysis to predict the flotation behavior of blended copper-molybdenum ore in seawater and to compare the effect of oxidation degree of each copper-molybdenum ore
Get PriceAug 01, 2015 The molybdenum content measured in the feed stream was approximately 0.10% of which 0.02% or 20% was determined by chemical methods to be in non-sulphide form. The sulphide minerals, which combined accounted for less than one percent of the ore mass were, pyrite, molybdenite and chalcopyrite respectively
Get PriceMar 30, 2012 Such as ore grade molybdenum ore is very low, only 0.1%, but by flotation, can be more than 45% of the concentrate grade; the application of flotation method to be fully comprehensive utilization of mineral resources. So, with the status of the flotation method of development of national economy will be increasingly important
Get PriceNowadays the main resources of molybdenum are disseminated copper porphyries. ln this ores, molybdenum content is very low, in the order of 0.05%. --rhe standard method is the obtaining of a Cu-Mo global concentrate and then separating the sulf des by using different process
Get PriceThe model was also tested at industrial flotation plant using 92 different datasets collected at different operational conditions and showed good accuracy for the prediction of Cu and Mo
Get PriceMar 15, 2019 Flotation reagents refer to the agent that used in mineral flotation process, which can adjust the flotation behavior of minerals thus achieving a good effect of mineral separation.Currently using flotation reagents is the most flexible, effective, and convenient method of controlling flotation process.The commonly used flotation reagents can be mainly divided into three types according to
Get PriceMolybdenum and copper-molybdenum porphyries are mined by open-pit or by underground methods. Once the ore has been crushed and ground, the metallic minerals are then separated from gangue minerals (or the molybdenum and copper from each other) by flotation
Get PriceMethod of flotation of copper molybdenum ores. The flotation method is edno-molybdenum ore, including grinding ore and collective flotation of copper and molybdenum in alkaline environment, created lime, characterized in that the collective flotation is carried out in the presence of the collector Aero-MX 3601 and the expander, then the bulk flotation concentrate after evaporation and
Get PriceMo and Cu containing phase were enriched with high yield by selective flotation of concentrate obtained from the concentrate. On the other hand, the most of Pb and Zn remained in tailing. In order to gain molybdenum, the appropriate concentrate was obtained by this process with hydrometallurgical method
Get PriceMar 25, 2019 The method of adding flotation reagents is mainly applicable to the flotation reagents which is easily soluble in water and which is not easily carried away by the foam, and which does not fail in the slurry due to the reaction, such as xanthate, Sodium bicarbonate and lime. Phased addition means that the flotation reagents is added to the
