Nowadays, in the given conditions of Uzbekistan, there is hardly any comprehensive technology either for processing industrial waste or extraction rare and precious metals at JSC “AGMK” with small amounts metals. The presence man-made containing platinum, palladium rhodium AGMK indicates that plant can manage industry, having been several years without recycling ore. This article discusses feas...

However, the conventional gold recovery process is cyanidation, due to the recent environmental laws; researchers are looking for alternative methods for the recovery of gold. Furthermore, the copper anode slime is one of the most important secondary sources of gold (about 1200 ppm). So, the main objective of the current work is gold separation from copper anode slime as a rich secondary source...

Sea-water samples collected by a variety of clean sampling techniques yielded consistent results for copper, cadmium, zinc, and nickel, which implies that representative, uncontaminated samples were obtained. A dithiocarbamate extraction method coupled with atomic absorption spectrometry and electro,thermal atomization is described which is essentially 100% quantitative for each of the four met...
