Flotation copper journal

Thus, before the flotation, process of sulfurization was made in order to change the ore structure and surface properties (9, 10 and 11). The sulfurized samples were subjected to flotation and the results were evaluated. 2. MATERIALS AND METHOD 2.1. Materials The copper ore containing gold and silver used in this study was obtained from

    Flotation of copper hydroxide precipitate has been investigated at total initial copper concentration 10 −2 M with sodium dodecylbenzenesulphonate (DBSNa) and dodecyldimethylbenzylammonium bromide (DDMBABr), both at initial concentration 10 −4 M. In particular, granulometric analysis of the precipitate and measurement of its electrokinetic potential were carried out over a wide range of

    Froth Flotation - an overview | ScienceDirect Topics

    The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely

    Effect of Desliming on Flotation Response of Kansanshi

    The Kansanshi mixed copper sulfide-oxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This paper presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was

    Influence of Lead Nitrate on Sulfurizing Flotation of a

    Copper-cobalt oxide ores contain several minerals that are economically treatable by concentration techniques. The most used technique is froth flotation in which selective reagents are used to recover more valuables. It is, therefore, important to examine the optimal doses of those reagents while investigating the behaviors of minerals at the same time

    Mar 11, 2018 The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na 2 S, CuSO 4 , and FeCl 3 on sulphidizing flotation of copper oxide. The results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe 3+ /sup inhibits the sulphidizing effect

    These flotation reagents preferentially adsorb at the solid–liquid interface, making the surface of wanted minerals water repellent and facilitating bubble-particle attachment. They are classified based on composition and whether they exist as cations, anions or molecular species in water. Therefore, collector molecules may be ionizing compounds, which dissociate into ions in water, or non

    The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then
