  • Molybdenum Ore Processing by Flotation

    2016-5-5 · This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite

  • A novel approach for preferential flotation recovery of ...

    2012-10-1 · 1. Introduction. Approximately 50% of the world’s molybdenum production comes from Cu–Mo ore as a by-product (Bulatovic, 2007).The flotation recovery of molybdenite from porphyry Cu–Mo ore is consistently lower than that of the copper sulfides (Bulatovic et al., 1998, Bulatovic, 2007, Triffett et al., 2008).In 2004, the price of molybdenum increased near 10-fold resulting in a renewed ...

Mil-ling ore before flotation was carried out in mills with steel grinding media. The finished milled ore fineness class was separated by the method of dry sieving.

  • Review of the flotation of molybdenite. Part I: Surface ...

    2016-3-10 · Particle size is a very important factor affecting flotation properties of molybdenite. In porphyry copper–molybdenite ores the flotation conditions (grinding, reagents, bubble size, etc.) all are optimized with respect to Cu and not Mo. Fig. 2 shows that the optimum flotation particle size for molybdenite is around 20 μm, and the size fraction 6.8 μm exhibits the lowest recovery and ...

  • Flotation separation of molybdenite from chalcopyrite ...

    2020-6-15 · Recoveries of molybdenite and chalcopyrite in single mineral, mineral mixtures and real ore flotation tests as a function of ferrate concentration or pH conditions are presented in Fig. 1.Without the addition of ferrate, the flotation recovery of molybdenite was similar to that of chalcopyrite at pH 7, as shown in Fig. 1(a). With an increase in the ferrate concentration, the recovery of ...

  • Synthesis of 2-ethyl-2-hexenal oxime and its flotation ...

    2014-11-1 · The molybdenum form was molybdenite and the gold forms were native gold and electrum. The significant amounts of non-sulfide gangue minerals were quartz, sericite, chlorite, illite and biotite. Undressed ore contains copper 0.38%, sulfur 1.42% and the oxidation ratio was 13.42%. The flotation flowsheet was illustrated in Fig. 1.

  • Molybdenite Flotation - 911 Metallurgist

    2017-8-27 · Factors Directly Affecting Molybdenite Flotation: The average molybdenite recovery in the copper concentrator for the first nine months of 1980 was 67.13%. In recent months, there has been approximately an 80% recovery of the molybdenite in the sand and slime rougher floats. The losses in the sand float are due mainly to fine molybdenite ...

  • Flotation Circuit Design for Adanac Moly Corp using a ...

    True flotation of non-sulphide gangue (NSG) only occurs due to attachment to molybdenite; the very low Mo grade of the ore results in very low NSG R max values. As a comparison, copper porphyry ore may exhibit NSG R max of 4 to 8%. The molybdenite recovery was generally poor under the standard size conditions with P 80 of 210 microns and “m ...

  • An effective approach for improving flotation recovery of ...

    2018-6-25 · in the flotation cell. Finally, the flotation concentrates and tailings were collected, filtered, dried, weighed and assayed. The principle flotation flowchart for recovering molybdenite fines from the molybdenum ore is depicted in Figure 1. Similarly,

  • Dithiouracil, a highly efficient depressant for the ...

    In this study, dithiouracil was first employed as a chalcopyrite depressant for efficiently separating molybdenite from chalcopyrite.According to the literature, dithiouracil is one of the drug intermediates, which has been used to produce the anticancer and antithyroid drugs (Lamsabhi et al., 2000).As shown in Fig. 1, dithiouracil contains N and S donor atoms, which is able to coordinate with ...
