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
For gold and silver bullion analysis and assay there are many different methods available, for example silver bullion can be analyzed by cupellation, by chemical titration, or by a combination of chemical titration and instrumental techniques. SGS experts are always available to assist you with selecting the analytical technique that is fit for your purposes. In fact, the critical aspect of
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
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

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

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
