groups: frothers, promoters, depressants, activators, sulphidizers, regulators. the order of these groups is no indication of their relative importanceand it is common for some reagents to fall into more than one group. see full list on 911metallurgist the tables on the following pages have been prepared to present in brief form pertinent information on a few of the more common reagents now being used in the flotation of metallic and nonmetallic minerals. a brief explanation of the headings in the table is as follows: reagent:reagents are listed alphabetically according to their technical names or manufacturers trade designation. description: includes chemical composition if known, color, and other physical characteristics useful in identification of the flotation reagent. usual method of feeding:whether in dry or liquid form. a large number of reagents are available in liquid form and naturally are best handled in wet reagent feeders, either full strength or diluted for greater accuracy in feeding. many dry reagents are best handled in solution form and in such cases common solution strengths are specified in percent under this heading. a 10% water solution of a reagent means 10 lbs. of dry reagent dissolved in 90 lbs. of water see full list on 911metallurgist the action of promoting reagents in increasing the contactangle at a water/mineral surface implies an increase in the interfacial tension and, therefore, a condition of increased molecular strain in the layer of water surrounding the particle. if two such mineral particles be brought together, the strain areas enveloping them will coalesce in the reduction of the tensionary system to a minimum. in effect, the particles will be pressed together. many such contacts normally occur in a pulp before and during flotation, with the result that the floatable minerals of sufficiently high contactangle are gathered together into flocks consisting of numbers of mineral particles. this action is termed flocculation , and obviously is greatly increased by agitation. the reverse action, that of deflocculation , takes place when complete wetting occurs, and no appreciable interfacial tension exists. under these conditions there is nothing to keep two particles of ore in contact should see full list on 911metallurgist here is a list flotation reagents chemicals preparedto present in brief form

flotation cells is affected by changes in unit load, feed quality, flotation reagent dosages, and the cell operating parameters of pulp level and aeration rates. in order to assure that the flotation cells are operating at maximum efficiency, the flotation reagent dosages should be adjusted after every change in feed rate or quality. in some plants, a considerable portion of the operators time is devoted to making these adjustments. in other cases, recoverable coal is lost to the slurry impoundment and flotation reagent is wasted due to operator neglect. accurate and reliable processing equipment and instrumentation is required to provide the operator with realtime feedback and assist in optimizing froth cell efficiency. this process of optimizing froth cell efficiency starts with a welldesigned flotation reagent delivery system. the flotation reagent pumps should be equipped with variablespeed drives so that the rates can be adjusted easily without havi see full list on 911metallurgist source:this article is a reproduction of an excerpt of in the public domain documents held in 911metallurgy corps private library. a series of simple math models have been developed to assist in the engineering analysis of batch lab data taken in a timerecovery fashion. the emphasis is to separate the overall effect of a reagent or operating condition change into two portions : the potential recovery achievable with the system at long times of flotation, r, and a measure of the rate at which this potential can be achieved, k. such patterns in r and k with changing conditions assist the engineer to make logical judgements on plant improvement studies. standard laboratory procedures usually concentrate on identifying some form of equilibrium recovery in a standard time frame but often overlook the rate profile at which this recovery was achieved. study has shown that in some plants, at least, changes in the rate, k, are more important relative to overall plant performance than c see full list on 911metallurgist
