Roasting of gold ore in the circulating fluidized bed

Roasting of gold ore in the circulating fluidized bed

Jan 01, 2005 The first Lurgi CFB roaster for whole-ore roasting was installed at Cortez Gold Mines in Nevada and commissioned in 1990. It was designed for calcining 1960 t/d of gold-bearing refractory ore. The measured SO 2 concentration in the off-gas was about 100 vppm. Therefore there was no need for installation of an SO 2 treatment plant. 4.2.1. Roasting

Ore containing copper and gold is crushed to a coarse size before the ore is sent to the treatment plant via a conveyor. At the treatment plant, the ore is crushed further and ground finely to slurry. The ore is initially processed by flotation, which produces copper / gold concentrate with 18% copper.

Gold recovery from high arsenic containing ores at Newmont

May 01, 2010 The Newmont roasting plant in Carlin, Nevada, commenced operating in December 1994. Over the years, refractory ores and pyrite concentrates from different gold deposits constituted the feed to the facilities. Historical plant performance indicated that the roasting temperature was the main variable affecting the structural characteristics of the calcine, which in turn affected the recovery of ...

The Role of Gravity and Intensive Cyanidation in

The gravity recoverable gold (GRG - as defined by Andre La Plante) content of the ore has been measured to be 70 per cent to 85 per cent in various tests with liberation grind size of approximately 106 m. This indicates gold is predominantly free and suitable for recovery by batch centrifugal concentrators into a low mass yield.
