2018-10-19 Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.

2020-6-17 Cyanidation is a method used in the extraction of gold from its ore. This extraction is done by converting the gold to a water-soluble form. The cyanidation process of gold extraction or the use of cyanide is the most common leaching process, used in the extraction of gold from its ores. Some countries do not approve of this method of gold ...

2014-2-11 Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high-lime solution prior to cyanidation.

This data focuses on the extraction kinetics of cyanide in cassava leaves during the soaking process. Various process parameters conducted at 26 ± 2 °C were evaluated, such as contact times (1-20 h) between the leaves and solvent, as well as the water-to-leaves ratios (spanning a range of 10-50 mL/g).

2015-2-2 The more you understand the process the more authentic it'll feel, imo. Best of luck. EDIT: You may want to consider switching to apricot kernels as opposed to apple seeds. The process is effectively the same but it's more realistic, since you'd need a LOT of apple seeds to get a decent amount of cyanide.
