Hydrochemically separation of gold from Copper Anode Slime by means of Thiourea solution
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...
متن کاملAnode Slime Gained During Electrolysis Process of Secondary Copper Anodes
The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

متن کاملKinetics of Sphalerite Leaching by Sodium Nitrate in Sulfuric Acid
In the present work, the extraction of zinc from a sphalerite concentrate using sodium nitrate as an oxidant in a sulfuric acid solution was investigated. The effective parameters such as the temperature, sulfuric acid and sodium nitrite concentrations, stirring speed, particle size, and solid/liquid (S/L) ratio were analyzed. The dissolution rate increased with increase in the sulfuric acid an...
متن کاملA comparison between intralesional hypertonic Sodium Chloride solution and Meglumine Antimoniate (Glucantime) injections in the treatment of cutaneous Leishmaniasis
Background and objective: Different local and systemic modalities are suggested in the treatment of cutaneous leishmaniasis, but the pentavalent antimony compounds are still considered as the first line of treatment. Regarding to increase in clinical drug resistance and adverse effects, efforts to find a more effective and safer drug is continuing. The objective of this study was to compa...
