The effect of blended ore cohesive phase strength on sintering indexes is shown in Fig. 8. As the blended ore cohesive phase strength increasing from 906 to 960 N, the sinter yield increases from 74.38 to 75.89%, the tumbler index increases from 63.05 to 65.67%. However, the sinter yield and the tumbler index decrease by further improving.

Taplin: One of the key areas is the development of new collectors due to the limited number of high-sulphide copper orebodies, and the increasing amount of oxide ore blended with sulphides. New collector development is targeted to allow for better recoveries using DTP, mercaptons and hydroxamate chemistries, increasing the typical low ...

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made …

3.6.6 Work index of ore blends. The blending of different ore types is a common practice to provide a consistent feed to a process in terms of uniform hardness or assay. When several different ore deposits of varying grindabilities are blended prior to closed circuit grinding, the work index of the ore is not an average or even a weighted ...

OREAS 147. OREAS 147 is a certified reference material (CRM) prepared from spodumene-rich pegmatite ore blended with granodiorite and with minor additions of Sn oxide ore and Nb concentrate. The pegmatite was sourced from the Greenbushes Mine located just south of the town of Greenbushes in the south-western corner of Western …

The Panxi region is located in the inner zone of the Emeishan LIP (He et al., 2003).In this region, there are five mafic–ultramafic layered intrusions, i.e., Panzhihua, Hongge, Baima, Xinjie and Taihe, hosting significant Fe-Ti oxide ore deposits (Fig. 1 b). Spatially, these intrusions are closely associated with coeval syenitic and granitic plutons …

In the case of Kanowna Belle, soft oxide ore encountered early in the life of the mine allowed a staged plant design. The Stage 1 plant consisted of a relatively low capital cost plant with the ability to treat high tonnages of oxide ore through a simple CIL circuit. Harder, refractory ore encountered

The blend of ore units in various ratios affects the efficiency of the process by decrementing the recovery and mass pull due to copper oxide-sulphate in the ore Madnueli V. HSC Chemistry® software was used to simulate the metallurgical response …

The hypothesis is that the flotation kinetics of blended copper-molybdenum ore in seawater can be estimated by the flotation kinetics of each copper and molybdenum mineral from each copper-molybdenum ore. Table 11 shows that the actual value of Rmax and k of blended copper-molybdenum ore is close enough to the estimated value of …

More than half of the global cobalt supply from primary sources is currently produced in the Democratic Republic of Congo (DRC) from ores containing copper-cobalt oxides or copper-cobalt sulphides. Where oxide and sulphide cobalt-bearing copper minerals occur together, efficient recovery of copper and cobalt is known to be extremely difficult. This study …

The oxide ore has a much higher grade than the mixed and sulphide ores but contributes less to the resource (Broughton et al., 2002). The preferred method for the flotation of oxide and mixed copper ores is sulphidisation. The reagents are typically sodium sulphide (Na 2 S) and sodium hydrosulphide (NaHS). Slug sulphidisation, which uses a ...
