Abstract

A method of geochemical prospecting where samples of soil, sediment and rock in a geological area are collected and each sample is contacted with a leach solution of water, glucose and glucose oxidase. The oxidase acts upon the glucose to produce gluconic acid and hydrogen peroxide. The leach solution reacts with manganese dioxide carrying trace metal elements and compounds in the samples to produce a leach reaction solution.
The leach reaction solution and the residue of the said sample are separated, and the leach reaction solution is analyzed to determine the trace metal content present. From the analysis, the mineral content of the geological area is predicted. The leach solution may also contain ascorbic acid, catalase, galactose oxidase and a salt such as water soluble metal cyanides and water soluble metal halides.
