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.... Gold cyanidation - Wikipedia. Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.

- CYANIDE IN GOLD PROCESSING THIOSULPHATE LEACHING Thiosulphate leaching is a process that removes gold from gold bearing ores without the use of cyanide. Although not as aggressive a leaching agent as cyanide, thiosulphate offers several technological advantages including its lower toxicity and greater efficiency with gold deposits associated with preg-robbing ores. The thiosulphate …
- where the gold dissolved to form a gold-cyanide solution. This solution was passed through a zinc tank where the gold fused to zinc shavings, separating from the cyanide. To separate the fused gold and zinc, the shavings were dipped into sulfuric acid, forming a gold sludge. This was washed with large amounts of water to remove the acid. The remaining gold was dried, smelted and poured into
