A direct potentiometric titration method for the determination of gold in ores and alloys is described. It is based on the reduction of Au(III) with iodide ions yielding accurate and reproducible results. Detection limit and sensitivity were and mg/l Au, respectively. The linear response range was between and 120 mg/l Au. The method can be used for the routine assay of gold in

Practical activity carrying out a titration Titration. There are a number of ways that you could carry out a titration. in Chemistry. This is an outline of the required steps to undertake one of
The extraction of gold by the cyanidemethod is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the wellknown solubility of gold in potassiumcyanide solution, a phenomenon said to have been
The titration technique is a simple process and can be experimented using such basic standardised tools within science in a childs science lab to more developed braches of chemistry within a working industry. The versatility of the titration method means that industries can use these various techniques to develop, learn and understand more about key chemical compounds. Titrations are

Unreactive metals such as gold are found in the Earth''s crust as the uncombined elements. However, most metals are found combined with other elements to form compounds. Most metals are extracted
When the gold concentration is lower than 3 g L 1 and the volume percentage of TBP is less than 10%, the plots of the extraction percentage of gold against the molar ratio of [TDMBA +] to [Au(CN) 2 ] and logDlog[TBP] (o) plot indicated that the stoichiometry of the extracted species is a 1 1 4 complex, TDMBA + Au(CN) 2 TBP.
