Gold mining industry has an important role to play in tackling climate change. At present, greenhouse gas emissions across the entire gold industry from exploration and extraction to downstream uses such as jewellerymaking contribute 36,793 tonnes of carbon dioxide (CO2) per tonne of the mineral.
Gold mining is an industry in transition, as companies strive proactively to prepare their operations for the move to a lowcarbon economy. The potential for decarbonisation is significant. Responsible gold mining companies are already taking action to address the
A high carbon lowgrade gold ore, in which gold mainly occurs in carbonaceous matters, is a typical refractory gold ore whose conventional cyanide leaching extraction is only %. In this paper, by the process of flotationroastingleaching, gold was effectively enriched and extracted.
#0183;#32;First, Guyana is on the cusp of a return to several externallybased largescale gold operations; for example, the leader, Canadianbased Guyana
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents
#0183;#32;Mining must be done as efficiently and safely as possible to reduce potential impacts on the environment on human health. After all, human and environmental health is as precious as gold. This week the Ministry of Natural Resources celebrates Mining Week under the theme: Extracting Minerals; Underscoring safety, Protecting the Environment.
Similarly, gold mining activities in Guyana of South America has contributed to forest depletion of 9000 ha which equals to 90% of the total deforestation in 2009 (Lowe, 2014).
Cyanide Use in Gold Mining. What is cyanide? Cyanide is a rapidly acting, potentially deadly chemical. Cyanide can mean any one of various compounds containing the chemical group CN: one atom of carbon (C) and one atom of nitrogen (N). Because it is organic, it reacts readily with living organisms.
For extracting gold from lowgrade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide as laid out in the International Cyanide Code. Gold refining
pivotal role in Guyanas transition to a lowcarbon economy. This paper examines these issues, drawing on data from Guyana, and international experience, and presents a series of recommendations to contribute to the discussion on how best to integrate Guyana [s important mining sector into its innovative LCDS.
Rising global demand for gold may lead to a growth in Guyana''s industry, though environmental concerns and a lack of infrastructure are slowing the process.
Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until the 1970''s, with the explosion of heap leaching of vast quantities of low grade gold ores, and subsequent production of many gallons of pregnant leach solution.
Gold Mining and the Environment. Dirty gold mining has ravaged landscapes, contaminated water supplies, and contributed to the destruction of vital ecosystems. Cyanide, mercury, and other toxic substances are regularly released into the environment due to dirty gold mining.

In 2009, Bharrat Jagdeo, Guyanas thenpresident, released his Low Carbon Development Strategy. While the LCDS acknowledges the importance of limiting deforestation and forest degradation from gold mining, and in the most recent update of the LCDS ( March 2013 ), the government claims that,
On 8th June 2009, Guyanas Low Carbon Development Strategy (LCDS) was launched. The Strategy outlines Guyanas vision to promote economic development, while at the same time addressing climate change. In March 2013, an Update to the LCDS was prepared and launched. It includes the progress of the LCDS and identifies new projects areas.
