GOLD EXTRACTION ALPHA MODULE COMPLEX
Basic terms: gold, gold extracting factory, hydrometallurgy, hypochlorite, chlorine, silver
Technology of gold extracting be cyanides provides use of harmful for human and dangerous for environment reagent, potassium cyanide, that is toxin of the 2-nd class of danger as accumulative active substance. Even minimal wastes act sufficiently on to environment. For neutralization of potassium cyanide has been used calcium and sodium hypochlorite or hydrogen peroxide. This a reason for mixture excavations, which contain sufficient amount of difficultly recyclable solution (volume of reservoirs is millions of cubic meters with appropriate cost for storage of wastes). It covers partially a problem of main effluent of potassium cyanide but doesn't resolve an evaporation of cyanide and its throw into atmosphere . Keeping in readiness of leach substance concerning all the process is a required condition for ecological protection of production excluding gas throws. For silver extracting from elaborated wastes mobile version of Alpha-Argentum” is developed. Production output of such mini-device is up to 70 dm3 solution per hour, what results as 0,5 kg silver per day.
