Simple method for extracting gold from electrical and electronic wastes using hydrometallurgical process
Background: This research studied the feasibility of a simple method for extracting gold from central processing units (CPUs) of computer circuit boards without solvent. Methods: Ceramic and composite CPUs of computer circuit boards were used. Gold was extracted using a hydrometallurgical method in six stages: grinding of CPUs, leaching in nitric acid, leaching in aqua regia, remov...

متن کاملAdvances towards a Clean Hydrometallurgical Process for Chromite
Because of the acute toxicity of Cr(VI)-bearing substances, the pollution problem caused by chromite process residue has become a worldwide concern. In the view of relevant studies, the technologies based on the alkali treatment cannot fundamentally resolve the pollution problem, because the oxidation of Cr(III) to Cr(VI) is unavoidable during chromite decomposition. In contrast, the oxidation ...
متن کاملDETERMINATION 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 کاملDecision Tables: Formalisation, Validation and Verification
The decision table is one of the simplest representations of the rules underlying a systematic decisionmaking process, and is especially valuable in the development of knowledge-based systems. A two dimensional table links all relevant combinations of input conditions to the desired combinations of output actions in a very intuitive way. This simplicity belies the complex considerations involve...
