Abstract
The paper presents results of the electrochemical technology investigation in the process of the rare- metal raw material dressing. The electrochemical technology is realised through the dressing cycles of tanta- lumniobium ores and the preparation operations of the reagents-collectors in the process of lithium-ore flotation. The authors studied the properties of oleic acid after electrolysis – surface tension, critical concen- tration of the micelle formation; calculated the parameters of the oliec acid adsorption.
