advanced modelling for scaleup of batch flotation resultswith the support of seven large mining firms. the methodology is divided into three key steps: 1. direct measurement of the kinetics of true flotation in the pulp, independent of hydraulic entrainment and . other froth effects in the batch cell2. benchmarking of the industrial plant over a broad range of ore types and operation conditions flotation machine for mineral ampmetallurgy jxsc machineflotation machine capacity 0.1820m³/min per cell feeding size 200 mesh no less than 80% application copper sulfide, g sulfide, zinc, lead, nickel, antimony, fluorite, tungsten, and other nonferrous metals, and also be used for coarse selection for ferrous metals and nonmetals. coal flotation mineral processing ampmetallurgyin coal flotation, the most commonly used collectors are oily materials collectors such as diesel oil and kerosene. for higher rank coals, the reagent consumption in flotation is low because of the high natural hydrophobicity of the coal. however, for lowrank coals (containing a greater amount of oxygen), flotation performance with these oily collectors is poor and large amount of collectors are required in order to obtain acceptable coal recovery. polyethoxylated nonyl phenols constitute a major part of the general class of nonionic surfactants, whose hydrophobic/hydrophilic characteristics can be controlled by varying the number of ethoxy groups on a hydrophobic nonyl phenol. see full list on 911metallurgist two bituminous coals, namely illinois no. 6 (from peabody coal co., marissa, il) and pittsburgh no. 8 (from rf coal co., warnock, oh) were used in this investigation. the proximate and sulfur analysis results of these two coals are given in table 1. chemical reagents used in this study are the following: 1. tetrahydrofufuryl butyrate (thf) c4h7och5oocc3h7 2. nonyl phenol (gh0) c9h19c6h4oh 3. polyethoxylated nonyl phenols (gh1.5, gh4 and gh6 for n = 1.5, 4 and 6) c9h19c6h4o(c2h4o)nh 4. nonyl benzene (ghb) c9h19c6h5 5. dodecane c12h56 6. 4methyl2pentanol (mibc) (ch5)2chch5chohch5 7. peg (200) monolaurate (ela) c11h53coo(c2h4o)4.5h see full list on 911metallurgist to obtain comparable combustible material recovery, the gh series of reagents with lower numbers of ethoxy groups require a considerable lower amount of reagent than for dodecane. since the nonionic surfactants contain a relatively small portion of polar groups in their structure, the flotation results for both coals indicates that these polar groups may play an important role in the interaction of the reagents with the surface of the coal. this interaction may be enhanced if the surface of the coal contains numerous oxygenated groups, as in the case of illinois no. 6 coal or a coal that has been weathered. because of this, the nonionic surfactants can spread on a hydrophilic coal surface much more easily than the oily collector dodecane, thereby creating a hydrophobic surface. see full list on 911metallurgist the flotation results of illinois no. 6 and pittsburgh no. 8 coals show that nonionic surfactants gh0, gh1.5, gh4 and thf are more effective collectors than the oily collector dodecane for both unoxidized and oxidized coals. although ethoxylated (with an average of 4.5 ethoxy groups) dodecanoic acid has a similar balance of hydrophobicity and hydrophilicity, it was a poor collector. see full list on 911metallurgist flotation developments ampbest practice international miningcurrent practice dictates that as the head grade of ore diminishes, rougher flotation requires more capacity, which is economically addressed by using very large flotation machines. there are certainly many advantages to using fewer large machines including asset maintenance, lower specific energy, and a manageable plant footprint. interpretation of flotation data for the design of process plantsthe flotation plant design was based on extensive benchscale testwork (including locked cycle tests) on drill core and many months of operation of a 30 tonne per hour pilot plant using the cleveland tin mine process plant, modified for the duty. the cadia concentrator was designed on an extensive benchscale variability testwork 1 froth flotation fundamental principlesno flotation can occur. contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in figure 5. figure 5: simplified schematic of a conventional flotation cell. the rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
