Cyanide Process

Cyanide Process. Cyanide process is also called as Macarthurforest 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.

Compressed ores require 1 unit to process, while uncompressed ores require 100 units. You cannot process uncompressed ores with less than 100 units of a single type, 75 units of Veldspar cannot be combined with 25 units of Dense Veldspar for processing. Both compressed and uncompressed ores yield the same amount of minerals per batch.

Metal values are recovered from ore concentrates by means of dry grinding, followed by a twostage leaching process in which the ground concentrate is first leached with sulfuric acid at a temperature of about 90° to 100° C. to selectively leach nickel and iron. The residue is then leached with a solution comprising sulfuric acid and NaOCl or H 2 O 2 to extract platinum, .

Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process. In addition, hydrometallurgical processes in particular have significant
