Process for recovering gold HARRINGTON;

Use of the silica gel in a dried or powdered form is not absolutely necessary; however, this will greatly enhance the recovery of gold and efficiency of the process. The chemical action of this catalyst is not presently known; however, it is theorized that the catalyst acts as a concentrating surface in accordance with heterocatalytic properties.

Interfacial properties of mercaptopropyl

Abstract Silica gel (SG) was modified using 3-mercaptopropyl trimethoxysilane (MPTMS) and used as an adsorbent for the recovery of gold(I) from a thiosulfate solution, based on the hard and soft acids and bases theory. The interfacial properties of the mercaptopropyl-functionalised silica gel (MP–SG) and its performance for the adsorption of gold(I) from a thiosulfate solution were examined.

Adsorption of Noble Metals Using Silica Gel Modified

Silica gel modified with a surfactant, Triton X-100 molecular assembly containing an extractant, 1-(2-pyridylazo)-2-naphthol, was prepared as an adsorbent to adsorb palladium, platinum, and gold. In this study, methods of metal recovery and mutual separation from the metal coexisting solution were studied by using the modified silica gel (PT100S). The effects of pH, chloride-ion, and metal-ion
