For example, a gold concentrator processes typical iron-gold ore, with a processing capacity of 200 tons/day and a gold grade of 10 grams/ton. All ores are calcined in a rotary calciner. The calcined ore is transported into the percolation tank with a mining cart. Lime is directly added to the ore, and the first cyanidation time is 12 hours.
