Tanzania gold mineral processing project

Case details

The ores in this project are mainly sulfide ores and oxide ores. The grade of the oxidized ore is 2.4g/t, and gold is the only valuable element that can be recovered. The gold leaching rate obtained by the all-mud cyanide gold extraction process is 93.75%; the gold content of the sulfide ore is 10.7g/t, and gold is the only valuable element. The gold leaching rate obtained by the all-mud cyanidation gold extraction process is 91.58%.

Xinhai mineral processing plan

Crushing stage:The process designed by Xinhai is a one-stage open-circuit crushing. The raw ore is sent to the crusher for crushing through the ore truck. The crushed qualified materials enter the screening machine, the undersized materials are sent to the grinding bin by the belt conveyor to prepare for the next stage of operation, and the oversized materials are returned to the crusher for crushing again;

Grinding and grading stage:< /strong>The process used is a closed-circuit grinding and cyclone classification operation;

Separation stage:Using the all-sludge cyanide gold extraction process, the gold-loaded carbon enters the desorption The electrolysis system extracts gold and smelts gold mud.

Tailings dry discharge:After the tailings are concentrated and dehydrated, they are dried style storage.

Project results

In the early stage of the project, Xinhai Mining was under project management , construction technology, resource supply, coordination work and other aspects have made comprehensive and detailed planning. During the project construction process, Xinhai Mining Co., Ltd. coordinated various measures and effectively responded to the severe shortage of material supplies, construction machinery, tools, and skilled workers in the project implementation area. Most of the equipment required for this project is a thin-walled tank. In conjunction with Xinhai Mining's efficient and reasonable measures, it effectively solved the problem of deformation of non-standard equipment during hoisting and transportation, ensuring the quality of project construction.
