The gold Giant Mine in the Yellowknife region operated from 1948 to 1999, releasing 237,000 tonnes of waste arsenic trioxide dust from ore extraction and roasting processes. Description: Gold was first discovered by prospectors in the Yellowknife area in 1896, who were headed north for Klondike riches. Nothing came of the Yellowknife discovery ...
Arsenic Pyrite Gold Extraction by Alkaline …
Gold recovery was proportional to arsenic extraction during the oxidative leach, with >90 pct Au extraction for arsenic extraction ≥ 89 pct. Silver extraction did not follow this trend and ranged from 47 to 62 pct. Cyanide consumption was 2.6 kg NaCN per metric ton of leach residue and 5.7 kg NaCN per metric ton for the untreated ore.

Arsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation. The ore contains 61 pct arsenopyrite, and the stoichiometric NaOH for complete extraction of arsenic is 1.88 mol of NaOH per 100 g ore according to equation 1. Table 4 indicates that more than stoichiometric NaOH was required to obtain high extraction of arsenic.get price
Evaluation of extraction methods for arsenic …
23.02.2007 · Having optimized the extraction conditions, the arsenic species in polluted soil and ore from the different pollution sources were extracted by microwave-assisted extraction with 0.5 M phosphate buffer as extractant. Arsenic species were quantitatively determined by high performance liquid chromatography on-line coupled with hydride generation atomic fluorescence spectrometry …
Extraction of arsenate and arsenite species from …
Extracting arsenic species from sediments while preserving the original arsenic redox integrity has been difficult. Hydrochloric acid extraction was used as a method for removal of arsenic from soil in a form suitable for speciation (Chappell et al., 1995). The strong acidic condition used is probably too aggressive and is suspected to lead to ...
Designing gold extraction processes: Performance …
Nine attributes: Ore type, Gold ore grade, Gold distribution, Gold stone size, Sulfide present, Arsenic sulfide, Copper sulfide, Iron sulfide and Clay present were modelled and several literature sources of actual gold mines and processes were used for acquiring cases for the system. After preliminary testing, functional evaluation of the built CBR system was carried out by using five real ...
Arsenic - Wikipedia
Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the second most commonly used semiconductor after doped silicon. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated stone products, herbicides, and insecticides. These applications are declining due to the toxicity of arsenic …
