The gold processor wants to maximize its gold production. The processing plant works from 8:00 to 20:00. The gold processor can spend $14,000 per day in raw materials. California environment regulations limit daily ore material extraction to 45 tons. Finally, a contract states that the amount of ore used from Alaska has to be at least 50 tons.
Gold cyanidation
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.It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, …
