| 摘要 | A method and apparatus necessary to carry out the method of continuous measurement, recordation, and correction of the varying electrode potential or E.M.F. within an ore slurry containing conditioning components in a mineral flotation system by immersing in cooperative relationship a tungsten oxide electrode and a silver chloride electrode in the slurry, relaying the potential thereby obtained to a recording instrument or to an optimizer or to both and either manually, or automatically by means of the optimizer, adjusting the rate of feed of at least one conditioning component of the slurry to correct the potential or E.M.F. to provide a more efficient process. | ||||||
| 权利要求 | 1. An apparatus for the continuous and automatic measurement, registration, and correction of the varying electrode potential established in an aqueous ore slurry composition, containing chloride ions and conditioning agents, at a stage prior to its being subjected to flotation, comprising: an electrode assembly consisting essentially of a tungsten oxide active electrode and a silver chloride reference electrode immersed directly in said slurry composition in cooperative relationship to provide an electrode potential between said electrodes; indicator means upon which said potential is continuously registered by means of electrical connections from said electrodes; control means for changing the rate of feed of an electrode potential modifying ingredieNt to said slurry composition in response to said indicator means to maintain a predetermined optimum potential so as to provide maximum mineral recovery; and means for conveying a signal from said indicator means to said control means. 2. The apparatus of claim 1 wherein the control means includes at least one valve for changing the rate of feed of the electrode potential modifying ingredient. 3. The apparatus of claim 1 wherein a peak-seeking optimizer is included between said electrode assembly and said indicator means and is electrically connected therebetween, whereby the rate of feed of said electrode modifying ingredient is automatically adjusted. |
