It Is Possible to Obtain A 100% Extraction of The Molybdenum Contained in Wulfenite
【China Molybdenum Industry News Network】
This envelope considerably retarded or entirely prevented the solution reaction. In order partly to overcome this, it was necessary to crush the ore to a grain size of about 200 mesh more or less.
I have discovered that it is possible to obtain a 100% extraction of the molybdenum contained in wulfenite, without its being necessary to crush the ore to a fineness beyond 60 to 80 mesh (0.246 to 0.175 millimeter sieve opening), while at the R. same time the molybdate obtained is purer than that obtained by prior art methods.
This improved result may be due to the fact that there is no formation of an interfering lead compound during the first step in the process as practiced 04i by me. Such a water-insoluble lead compound is formed in the case of sulphide, sulphate and carbonate reagents used heretofore. However, this explanation of the reason why it is not necessary to crush the ore fine is merely a theory, and 4:; the advantageous results may be due to other causes.
