DETERMINATION OF THE OPTIMUM CONDITIONS FOR RECOVERY OF GOLD FROM ZARSHURAN REFRACTORY GOLD SULFIDE ORE
The orthogonal array design has been used to determine the optimum conditions for gold recovery from Zarshuran refractory gold sulfide ore (Iran) by direct cyanidation and roasting-cyanidation. The Taguchi method was used as the experimental design to determine the optimum conditions of dissolution behavior of gold with cyanidation and roasting-cyanidation from Zarshuran refractory gold ore . T...
متن کاملLeaching of Gold and Silver from Crushed Au-Ag Wastes
Au-Ag noble metal wastes represent a wide range of waste types and forms with various ballast elements and components. The thiourea process of gold and silver extraction from ores, concentrates or secondary raw materials consists of gold and silver leaching into the thiourea solution and the consequent precipitation of these metals from the solution. Due to the non-toxic character of thiourea i...
متن کاملComplexes of Gold(I) with a Chiral Diphosphine Ligand: A Polymer with Both Au···Ag and Ag···Ag Metallophilic Bonds
Dedicated to Professor Hubert Schmidbaur, the grand master of gold chemistry, on the occasion of his 75th birthday The chemistry of gold(I) with the ligand binap = 2,2′-bis(diphenylphosphino)-1,1′ -binaphthyl is reported. Reaction of [Au2Cl2(μ-binap)] with silver trifluoroacetate gave the corresponding complex [Au2(O2CCF3)2(μ-binap)], and crystallization in the presence of excess silver trifluo...
متن کاملSynthesis and characterization of Au core-Au-Ag shell nanoparticles from gold seeds: impacts of glycine concentration and pH.
This paper describes the preparation of Au core-Au-Ag shell nanoparticles (NPs) in different morphologies by controlling both the pH and the glycine concentration. Using a seed-growth method, we prepared high-quality Au core-Au-Ag shell NPs from a glycine solution under alkaline conditions (pH>8.5). By controlling both the pH and the glycine concentration, we prepared dumbbell-shaped and peanut...
متن کاملHeterojunction double dumb - bell Ag 2 Te – Te – Ag 2 Te nanowires
Growth of isolated axial heterojunction nanowires by a solution phase growth process is reported. The dumb-bell shaped nanowires contain two silver telluride sections at the extremes joined by a tellurium section. Reaction of silver nitrate with tellurium NWs in aqueous solution at a molar ratio of 1 : 1 leads to the formation of amorphous partially silver reacted Te NWs. Low temperature (75 C)...
