The solubilities of various metals in mercury at 18° C. are noted in the accompanying table. Concentration of the saturated amalgam usually results in the precipitation of the dissolved solute as a mercuride, rarely in the form of the free metal. It should be noted that metals chemically and physically similar to mercury are characterized by high solubility. The farther removed in the Mendeleev periodic table the metals are from mercury the less soluble they become. Actually none of the metals except thallium is extremely soluble consequently, methods leading to the preparation of amalgams often give products... 

Mineral matter was a Deis ter table concentrate from Robena mine coal. It contained 68% pyrite and less than 4% organic material. The remainder was largely clay. In one case, a handpicked sample taken from a pyrite nodule found in a Pittsburgh seam coal was used. The microcrystals were crushed and sieved to 325 x 400 mesh. X-ray diffraction analysis indicated the only major component was pyrite, with a trace of marcasite also present. After heating in tetralin at 450°C for 15 min., the X-ray diffraction patterns of the recovered microcrystals indicated conversion was complete to pyrrhotite 1C. The coal was hvB, Homestead Mine, Kentucky, ground to pass 200 mesh. Ash and pyrite contents were 16.8% and 4.9%, respectively. The asphaltene was a homogenized mixture of samples isolated from liquid products derived from Pittsburgh seam, hvA coal. Its ash content was <0.1%( ). 

Previous tables concentrated on reactivity results with typical molecules for comparison purposes. A summary of the reactivity patterns and general conditions is provided in the following (Table 1.11). 

These concentration processes aro of comparatively recent invention, and are increasingly applied to the treatment of low grade sulphide ores and the tailings from table concentrations.
