700t/d gold ore project of Alitimad was one of the EPC projects contracted by Xinhai. Xinhai provided whole mineral processing plant service, including testwork & study on ore, plant design & construction design, complete equipment manufacture and purchase, plant construction and equipment installation, commissioning and operation.
In the project, the gold content was 2.97g/t; the ores were dry and dusty with maximum particle size of 140mm. Xinhai provided scientific and perfect laboratory test and research service, and took it as the plant design and construction basis. This mineral processing plant adopted all-slime cyanidation technology: Crushing process adopted one-stage open circuit crushing; grinding process adopted onestage closed circuit; grinding product adopted cyanidation CIP process to extract gold; gold loaded carbon was sent into high pressure and temperature desorption and electrolysis system for gold extraction; gold mud was smelted to gain alloy gold; leached tailings were dry-stacked after filter pressing and dewatering.
This project had been successfully put into production and had produced qualified products.
