S. Chander, D.R. Nagaraj, in Encyclopedia of Separation Science, 2007 Reagent Selection and Optimization. In the 1920s and 1930s the number of commercially used flotation reagents was relatively small, and reagent selection for a given application was relatively straightforward. As the number and diversity of commercially available flotation reagents steadily increased to meet the ever ...
Advantage high reagent concentration, easy to add. Several-time dosing Add the flotation reagents in several times along roughing, concentrating and scavenging. Generally, add 6070 of the total amount before the flotation stage, and the rest of reagents is added to

Oct 14, 2014 Xinhai automatic flotation control system can be applied to metal mines, nonferrous metal mines and nonmetallic minerals. It mainly contains pulp density, the amount of reagent, the liquid level of flotation tank and inflating volume. Finally, it can enhance the concentrate grade and recovery, stabilize the flotation process, and reduce the costs in the dosage of reagent and labor personnel.
May 30, 2016 Wet Reagent Feeder is a compact, self-contained unit mounted on a wood base. It occupies minimum floor space and may be conveniently placed near the grinding or flotation circuit as required. The Wet Reagent Feeder is equipped with a revolving disc, carrying a variable number of cups around its outer rim.
Advanced flotation process control system at a base metal concentrator Mvuyiso Gqwaru1 , ... feeding the Rougher floatation cells, thus preventing the effect of surges in the floatation cells, and to ... with overdosing of the pH reagents completely eliminated.
Jan 01, 2008 The control system updates automatically flotation reagent feeding when the boundary conditions changes. Successfully industrial application has shown that the concentrate grate has been increased by 0.52, the tailing grade has been reduced by 4, and the consumption of the flotation reagent feeding has been reduced by 17.5.
Flotation System . 2 these factors into account in froth flotation operations. Changes in the settings of one factor such as feed rate will automatically cause or demand changes in other parts of the system such as flotation rate, particle size recovery, air flow, pulp density, etc. As a result, it is difficult to
frother reagent system. Plant trials were conducted in a flotation plant for validating the findings obtained at laboratory scale studies. Results and discussion Flotation tests using a series of single reagents . A series of single reagents Sokem 580C series amp Sokem 590C was tried for coal flotation at different dosages of each reagent.
correct reagent regime and addition system can provide improvement opportunities in recovery and grade. Also reagent optimization can reduce reagent costs for the rougher, scavenger and cleaner flotation units. Reagents were optimized in the flotation of hot floats from the plant at laboratory scale.

Apr 13, 2016 Rougher flotation may be accomplished at a relatively coarse grind and the subsequent regrind performed on a comparatively small tonnage. Copper Flotation Reagents. Lime is usually added to the ball mill feed by a Dry Reagent Feeder. The frother and promoter are added in the classifier prior to flotation to realize the full effect of the reagent.
The presence of slimes in flotation systems results in deleterious effects on re-covery, selectivity and reagent consumption . The problematic nature i10 m-posed by slimes on flotation is attributable to their 1 small mass, 2 high surface area and 3 high surface energy
Optimization of CuZn Massive Sulphide Flotation by Selective Reagents ... 4 were used as 2 depressant systems for pyritesphal- ... where C is the weight percent of the feed to the concen-
A range of companies make flotation reagents and flotation equipment for the mineral-processing industry. Mining Magazine talked to some of the main players about mining projects that they have supplied, and any recent product releases ArrMaz is constantly improving reagent performance by plant testing. In this image, it is setting up to run
960 second laboratory scale conventional flotation on the same feed material. The apparent improvement in flotation kinetics is attributed to the novel high intensity aeration system, which provides efficient bubble-particle contact thereby shortening the residence time
Aug 16, 2019 Five. Reagent system. In the flotation process, the addition system of reagents is often referred to as prescription, which mainly refers to the type, quantity, place, order and preparation method of the reagents. It has been proved that many cases are caused by improper flotation reagent system when the flotation index is decreased. 1. Reagent ...
Sep 15, 2005 Flotation cells have three main control parameters. 1 reagent dosing rate 2 froth depth and 3 air addition. rate. Many other parameters may vary such as feed rate, particle. size distribution and head grade, however these are the output. of upstream processes and are not controlled in the flotation. circuit itself.
particle sizes and applying a reagent regime that is known to give the desired minerals separation. Following a review of the initial flotation testwork results alterations are made to grind size coarser or finer, reagent system and flotation times to further enhance mineral recovery.
Dec 20, 2018 Froth Flotation machine plays an indispensable role in the mineral beneficiation process, flotation is susceptible to a number of factors during the process, including grinding fineness, slurry concentration, pulp pH, pharmaceutical system, aeration and agitation, flotation time, water quality and other process factors.

Parameters analyzed are e.g. shade of gray, air bubble
the system translates the fuzzy processing data in to a control system output. Thereby , combining this three -step process, a PLC with fuzzy logic capabilities can sensibly determine the proper control response to system inputs based on collective predefined criteria. Fuzzy logic thereby taps into the process knowledge of the
