Zinc deficiency (plant disorder)

Zinc is an essential micronutrient which means it is essential for plant growth and development, but is required in very small quantities. Although zinc requirements vary among crops, zinc leaf concentrations (on a dry matter basis) in the range 20 to 100 mg/kg are adequate for most crops.

Gold cyanidation

Gold cyanidation. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other industrial processes such as plastics, adhesives, and pesticides.

Impacts of artisanal gold mining on soil, water and plant

Cyanidation water had higher average Al, As, Co, Mn, Ni and Zn concentrations than all other types of water. High value obtained for Zn in cyanidation water is explained by the use of Zn chips for carburization of gold in solution. It is leaching of ore with use of sodium, cyanide and nitric acid that would have mobilized As and Co.
