RBCs, cyanide and thiocyanate are degraded by oxidative reactions to ammonia, carbonate, and sulfate. In the second set of RBCs, ammonia is converted to nitrate. Flow charts of both the process and the mechanisms of Homestake aerobic biological treatment process are shown in Fig. 2 .
The process of producing a coating, usually metallic, on a surface by the action of electric current . The depos . ition of a metallic coating onto an object is achieved by putting a negative charge on the object to be coated and immersing it into a solution which contains a salt of the metal to be deposited.
Other potential alternatives to cyanide include the Haber Gold Process, which technology company Haber says is both nontoxic and more efficient than conventional solvents, such as mercury and cyanide. Additionally, the cyanidefree biocatalyzed leaching process from YES Technologies, is said to be 200 times less toxic than cyanide.
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. Also, like I said my orgo is a bit rusty so if someone else could look over this that would be nice.

Process of dissolving powdered gold and silver ores in a weak solution of sodium cyanide or potassium cyanide; the precious metals are precipitated from solution by zinc. Also known as cyanidation.
Cyanide process Revolvy. Nov 13, 2005 · Gold cyanidation (also known as the cyanide process or the MacArthurForrest process ) is a metallurgical technique for extracting gold from lowgrade ore by >>Online; cyanide process Infoplease. cyanidation, method for extracting gold from its ore.
pH and REDOX (ORP) Control in Cyanide Wastewater Treatment Systems In order to ensure that the alkaline chlorination process proceeds safely and efficiently, it is important to monitor pH and ORP during each oxidation step. CYANIDE WASTEWATER TREATMENT PROCESS DIAGRAM DESIGNED AND ASSEMED IN CAIORNIA SA
The cyanide is regenerated as free cyanide and recycled to the gold extraction circuit. We have designed and constructed fullscale plants, provided process review and commissioning for a plant under construction, and carried out flowsheet development and testing programs for SART.
Cyanide is toxic to humans and may cause death if exposed to high enough doses. Liquid or gaseous hydrogen cyanide, as well as salts of cyanide can enter the b. ody through inhalation, ingestion or absorption through the eyes and skin. It is toxic as it prevents cells using oxygen in the bloodstream. The process:
Cyanide Poisoning Cyanide works rapidly and is potentially deadly, according to the Centers for Disease Control and Prevention. Although the gas form that you breathe is the most poisonous, eating cyanide can be harmful, too.
Inhaling or swallowing sodium cyanide blocks oxygen transport causing serious medical problems and ultimately death. However, the safety of sodium cyanide changes if it is present during an explosion.
Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the MerrillCrowe process. In the latter process, the goldbearing solution is deoxygenated and passed through a filterpress, where the gold is displaced from solution by reduction with zinc metal powder.
