100TPD Gold Tailings CIP Production Line

The equipment includes a jaw crusher (PE-400×600) for coarse crushing of tailings; A closed-loop grinding system consisting of a ball mill (MQG1500×3000, equipped with a 45kW motor) and a spiral classifier is used to grind materials to -200 mesh, accounting for over 90%; High efficiency thickener (NT-12, diameter 12m) is used for slurry concentration to 40-45% concentration; A 4-6 level CIP adsorption tank (XJB-30, single tank capacity 30m ³, equipped with variable frequency stirring) is used to form a countercurrent adsorption system. The activated carbon concentration is maintained at 10-15g/L, the sodium cyanide concentration is 0.02-0.04%, the pH value is 10-11, and the adsorption time is 24 hours; After being separated by a safety screen, the gold loaded carbon enters the desorption electrolysis system (desorption column with a diameter of 800 × 4500mm, working pressure of 0.5MPa, temperature of 135 ℃), and the electrolytic cell (stainless steel cathode) produces gold sludge; The tailings are dehydrated by a box type filter press (XAZ50/800, filtration area 50 ㎡) to a moisture content of ≤ 18% before being discharged dry; Supporting sewage treatment system to achieve wastewater recycling; The automated control system monitors the CN ⁻ concentration (0-50ppm), pH value (9-11), and carbon gold loading (2-4kg/t) in real-time.
