Are there alternatives to cyanide?
Banning Cyanide Use in Mining - Frequently Asked QuestionsThe U.S. Environmental Protection Agency lists several alternatives to cyanide, including starch and sulfur dioxide. In 1999, 16 of 18 leading U.S. zinc mines and 11 of 15 leading U.S. copper mines did not use cyanide. For gold and silver extraction, the Haber Gold Process (HGP) has been proposed as a possible alternative.
Related QuestionsWhat is cyanide?
Banning Cyanide Use in Mining - Frequently Asked QuestionsCyanide refers to a group of compounds made of carbon and nitrogen. Cyanide solutions readily bond with gold, silver and other metals, which is why the mining industry uses it. Cyanide is usually stored and transported as a solid. It is stable when dry. Most cyanide solids will dissolve in water to produce toxic cyanide gas. Cyanide gas is colorless and smells like bitter almonds.

Sodium cyanide and potassium cyanide are both white solids with a bitter, almond-like odor in damp air. In certain plant foods, including almonds, millet sprouts, lima beans, soy, spinach, bamboo shoots, and cassava roots (which are a major source of food in tropical countries), cyanides occur naturally as part of sugars or other naturally-occurring compounds.Related Questions

Related QuestionsAre There Any Alternatives To Dentures?
Frequently Asked QuestionsDentures are no longer the only way to restore a mouth that has little or no non-restorable teeth. Strategically placed support, or implants, can now be used to support permanently cemented bridges, eliminating the need for a denture. The cost tends to be greater, but the implants and bridges more closely resemble the "feel" of real teeth. Dental implants are becoming the alternative of choice to dentures, but not everyone is a candidate for implants. Call your dentist for advice.

The Truth About Vivisectionanimal alternative falls into one of three categories: replacement of an animal method; reduction in the number of animals used; or refinement of the experimental design and methods to reduce pain and distress to animals. It is important to understand that a procedure that uses animals can still be considered an alternative by the scientific community. Eye Irritancy Tests: In these tests, a liquid, flake, granule, or powdered substance is dropped into the eyes of animals, usually rabbits.

Q.-How come the cyanide does not poison us?
Cancer F.A.Q'sA.- There is another important enzyme called "rhodanese", which we shall identify as the "protecting enzyme". (Since about 1965, rhodanese has been identified in the technical literature as thiosulfate transulfurase.) The reason is that it has the ability to neutralize cyanide by converting it instantly into by-products that actually are beneficial and essential to health.

Related QuestionsWhat are the dangers of using cyanide?
Banning Cyanide Use in Mining - Frequently Asked QuestionsCyanide reacts with many other elements and is known to breakdown into several hundred different cyanide-related compounds. Despite the risks posed by these breakdown compounds, mines are not required to monitor or report these chemicals. Cyanide-leaching, as practiced by the modern mining industry, is inherently dangerous to the environment and the communities surrounding a mine that uses the process. As cyanide use continues, so do serious accidents and spills.
