In order to erase the cyanides issue, we followed two guidelines: look for a system to solve the failures of the old technology and develop innovative systems with almost zero environmental impact. All trying to increase the yield for the owners and improve the conditions of the workers.
Our cavitation device, the Empowering Device, triggers an oxidation reaction of cyanides typical of processing in gold mines, by mixing the waters by cyanides with CO2 and compressed air, inside a special controlled cavitation system that allows the molecules to come into contact with each other, with the others with great ease and speed.
If should be a case where the aforementioned reaction could not self-sustain, then in the presence of particularly difficult to treat pollution, the liquids will be further added with pure oxygen, taken from the atmospheric air through a package sub-system membranes connected to the cavitator. The nitrogen will be separated, taking advantage of the different elution speed of the two molecules making up the air, and subsequently recovered to be used in maintenance, in safety devices and the remaining, if bottled, could also be sold on the market.
In extreme cases, a mixture of ozone will be introduced into the cavitation device which, thanks to the nascent oxygen, will completely oxidize any residual cyanides.
In sequence, the chemical reactions obtained within our apparatus are the following:
- the mixed air in intensive mode, with priming of a small initial amount of CO2, evaporates the HCN and oxidizes it in the much less toxic HOCN;
- with further supply of air / oxygen / ozone, the reaction continues to form other CO2, necessary to self-sustain the reaction, and ammonia;
- lastly these two molecules react by producing ammonium carbonate and causing the disappearance of cyanides in the water.
Ammonium carbonate is a crystalline salt that is neither dangerous for man nor for the environment, not explosive, easily separable in a desiccator / crystallizer - even a simple vibrating tape with hot air blowing - and is subject to safe sale on the market being an intermediate for the chemical industry.
The progress of the reaction and therefore how much cyanide is still present in the waters are kept under control and followed by titrating the samples taken with sodium permanganate.
The success of the water purification polluted by cyanides is practically total.
The whole plant can be installed in containers to be easily transported to the edges of cyanide ponds.
In inaccessible areas, difficult to be reached, a little gasifier fueled by pawlonia to be planted nearby can excellently provide part of the electrical energy necessary for the operation of various devices as well as the production of CO2, in the desired quality, directly on site.
The other plants (bottling, extraction of gas from the atmosphere, production of electricity, bagging of salts produced, etc.) will be entered in other specially designed containers.
