1. Introduction. In the past 25 years, most of the development in the cyanidation of gold has occurred in response to the decreasing grade of deposits, the shift from surface mining to underground mining, the increasing complexity of treatment, and the concern for environmental constraints.
Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes ...
The claims by Nemec et al. (1936) may well have been based on faulty analytical work. Although there are no recorded cases of genuine gold accumulators or gold indicators, specific plant communities can sometimes indicate the presence of rock types which are potentially auriferous.

Depending on where they are growing and the presence of elements, plants can even contain lead, cadmium, gold, or radioactive strontium, platinum, and uranium (Moore et al. 2003). However, only a few elements are deemed essential to plant growth and development. Plants require for their growth and reproduction at least 16 essential elements.
