Sotagold

The research began in 1999, for the search of technological solutions for standard gold mining factories, at which fine carbon is used during the sorption process of precious metals. In 2012 this new technology was moved to U.S. and became the foundation of Sotagold LLC. Currently the patent is approved in USA. These technological processes minimiz... e the loss of gold (Au) with a fraction of worn out fine carbon, which contains tiny dispersed carbon components. It is necessary to solve the following problems: To find a technical solution to detect and accumulate fine carbon; To suggest an effective way of its processing. The processing of fine carbon by usual methods does not allow for the sufficient extraction of gold. The above mentioned feature is related to structural, granular metric ( d 60 mcm) and chemical features of fine carbon. Under high temperatures the minerals of barren rock (from 30-70%) in fine carbon cover gold clusters with glassy film, which makes the interaction with cyanide difficult. Furthermore, there are graphite like structures that are resistant to the oxidation at the carbon stage. Considering the above-mentioned specifics of fine carbon, we have worked out an effective way of processing, which combines the process of mechanical activation and low temperature gasification of the carbon component. All this allows extraction of gold for more than 94% from fine carbon. We developed a simple technical solution using standard equipment. The realization of the process requires no substantial processing costs, nor does it have an ecological effect on the environment. The process has been successfully tested in industrial conditions. The enterprise on treatment of gold-containing activated fine carbon should be based on regional principle, i.e. treat the raw material delivered from the plants of the whole region (country, province, several provinces, etc.). The enterprise should be located where fine carbon can be delivered (for example, by railway or motor road). 1. There are many methods ...Read More
