Electrolytic deposition of molybdenum
Abstract
In the work on the extraction of molybdenum from ores carried out by the Scientific Research Department of the Leningrad Mining Institute, the issue of recovering molybdenum from leaching solutions arose. Since electrolytic deposition, due to its greater operational simplicity, yields a product in the form of an oxygen compound of molybdenum that is free from other metals and distinguished by higher purity, it is of great practical interest to study the process of cathodic deposition of molybdenum hydroxide from its solutions. In the experiments described below, we experimentally studied the course of the process of electrolytic deposition of hydroxide from solutions of ammonium molybdate. The influence of various factors, such as the concentration of molybdenum in the solution, current density, temperature, and the concentration of salts of other metals, on the hydroxide deposition process was investigated. The presented results show that for satisfactory cathodic deposition of molybdenum hydroxide, a number of conditions must be observed (see the article).
