Tanzania 150t/d Gold Mineral Processing Plant

XINHAI SOLUTION

• 01

  Crushing and screening: raw materials were transported by trucks, and two-stage closed-circuit crushing was adopted.

• 02

  Grinding and classification: After the surge fine ore bin, crushed products entered the two-stage closed-circuit grinding and classification system.

• 03

  Gravity concentration: gravity concentration system was added between the first-stage ball mill grinding and closed-circuit classification. Jigs and shaking tables were used for roughing and concentration respectively.Cyanide leaching: the two-stage classification cyclone overflow entered the cyanide leaching system which adopted eight-stage leaching and absorption and reverse carbon extraction.Desorption electrolysis and smelting: the saturated gold-bearing carbon was fed to the high-temperature high-voltage desorption electrolysis system for gold extraction. The gold slime, which had a high grade Au, was fed to the high-frequency furnace to produce crude gold ingots.

• 04

  Tailings dry stacking: tailings were dehydrated by filter press. The dehydrated tailings (20-25% water) were transported to the tailings pond, while the filtrate was recycled to achieve no discharge of production sewage.
