The Sudan 700t/d gold mineral processing plant was an EPC+M+O project. The ore of this project contained 2.97g/t of gold, most of which were earthy minerals with particle size below 2mm. A small part of the ore was blocky minerals, and the maximum particle size was 70mm.
One-stage open-circuit crushing.
CIP-desorption electrolysis-smelting.
Press filtering and tailings dry stacking.
The project produced qualified products which brought substantial profits, and created new job opportunities. Effective measures were taken for the disposal of waste water and gas, leaching slag, smelting gas, tailings, dust and garbage and the control over noise. As a result, economic, environmental and social benefits were achieved.
