Sherritt Gordon Mines

The example being considered under zinc ore pertains to acid pressure leaching of zinc concentrates developed by Sherritt Gordon Mines Ltd. in Canada. The basic reaction involved is... 

From 1973 until 2002, Sherritt Gordon Mines Ltd. and later Hudson Bay Mining and Smelting, extracted copper and zinc ore from volcaniclastic and siliciclastic sequences of the Rusty Lake Greenstone Belt at the Ruttan Mine near Leaf Rapids, Manitoba, Canada.

Sherritt ammonia pressure leaching. This hydrometallurgical process was first implemented in 1954 by Sherritt Gordon Mines in Fort Saskatchewan, Alberta, Canada. In this process, the finely ground nickel sulfide concentrates obtained after flotation or the metal matte are reacted at 80 to 95°C in a high-pressure autoclave under 850 kPa with an oxygenated ammonia or ammonia-ammonium sulfate liquor. Ammonia dissolves nickel and, to a lesser extent, cobalt, zinc, and copper by forming soluble ammonia complex cations as follows ...

This comes to 25 million Btu, an easy-to-remember rate that was used in an advertisement promoting these new energy-efficient plants. Kellogg s modification that reduced the total energy need below 25 million Btu was first commercialized at the Sherritt Gordon Mines ammonia plant (1,000 t NH3/day capacity) at Fort Saskatchewan, Alberta, in 1983. 

The Sherridon complex in northwest Manitoba is host to the Sherritt Gordon Cu-Zn mines that collectively produced some 8 million tonnes grading approximately 2% Cu and 5% Zn, as well as six other smaller unexploited Cu-Zn sulfide deposits. Correlation between the Sherridon complex and the Flin Flon -Snow Lake metavolcanic belt (Zwanzig...
