gold extraction from fine carbon

Feb 04, 2014 · Re: gold extraction from fine carbon. Post. by Palladium » July 13th, 2013, 7:52 am. The carbon that is left over is probably from an incomplete combustion process. The carbon needs oxygen to burn. In the retort it is starved for oxygen so what carbon you have left over is probably because it was oxygen starved.

Catalytic hydrogenation of cyclohexene: Part II. Liquid ...

Sep 01, 1978 · The areal rate of liquid phase hydrogenation of cyclohexene on supported platinum alysts does not depend on the nature of the support. Nor does it depend on particle size of the metal. The rate constant is independent of the nature of the solvent when the concentration of hydrogen in it is expressed as its measured or calculated solubility. All observations are compatible with the idea that ...
