Organic matter control on the distribution of arsenic in ...
Gold mines near Yellowknife, Northwest Territories, subarctic Canada, operated from 1938 to 2004 and released >20,000t of arsenic trioxide (As 2 O 3) to the environment through stack emissions. This release resulted in elevated arsenic concentrations in lake surface waters and sediments relative to Canadian drinking water standards and guidelines for the protection of aquatic life.
Gold Ore Roasting Techniques
· Roasting and Processing Sulphotelluride ore to recover gold. This roasting plant, since closed down, was equipped with eight standard 70spindle Edwards roasters, though only four were finally in use. Fuel was supplied to four ports on each furnace in the form of pulverized lignite of 8500 value prepared at a central plant.

Gold Process Mineralogy
processing techniques required, gold . ores are commonly classified into two major ores. Typically, freemilling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores give low gold recoveries only with the use of significantly more reagents or more complex pretreatment process. 1 ...

Bousquet winding down
· The grade of the mined and processed ore is expected to be g/t Au in 2001. The gold recovery will likely decrease slightly, due to higher production from a zone with a lower recovery rate. The processing cost per tonne is expected to remain the same. About US3 million will be spent in 2001 on ore development.

Alamos Gold
Ore is processed through an 8,000 tpd single stage semiautogenous grinding circuit followed by flotation. The flotation concentrate is further ground and leached in a carboninleach (CIL) circuit. The flotation tailings are also leached in a CIL circuit. Gold is recovered from the carbon followed by electrowinning and pouring of doré bars.

Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite, where it occurs in both the chemically bonded state and as nanosize grains of metallic gold. During roasting or pressure oxidation, the sulfide matrix is destroyed and essentially all the gold is converted to the metallic form. The liberated gold is readily dissolved in conventional cyanide media ...
