Tanzania 1200tpd gold mineral processing project has finished the installation and commissioning part recently, now has been put into operation, during the installation and commissioning process, Xinhai employees carry forward the work style of working hard and develop the rigorous attitude to guarantee high quality finishment of the work in short period. The production line has got anticipated recovery rate, Xinhai employees got highly appreciated from the customer.
Xinhai Tanzania 1200tpd gold mineral processing project is located in Africa,thus has big differences from domestic one in project management, construction technology,resource supply and work coordination.
Pictured above is the grinding and thickening panorama of the Xinhai Tanzania 1200tpd gold mineral process plant.Pictured right is a group photo from project site of Xinhai employees with the customer.
Mainly includes thickening,cyaninding and desorption electrosis parts.Main work of the installation and commissioning includes:
1.Install the equipment such as thickening,cyaniding,desorption electrosis system.2.Install the pipelines and operation platforms (exclude tailings pipelines of outdoors);3.The electric power, water supply and drainage.(exclude water supply from water source)
This project applys all slime cyanidation to leach gold,the ore mainly sulfide ore and oxidized ore.
This project applys all slime cyanidation to leach gold,the ores mainly are sulfide ore and oxidized ore.Oxidized ore has grade of 2.4g/t,gold is the only valuable element that can be recovered and the all slime cyanidation get 93.75% recovery rate of gold; Sulfide ore has grade of 10.7g/t,gold is the only valuable element that can be recovered and the all slime cyanidation get 91.58% recovery rate of gold;
Above is part of the desorption electrolysis system of the project,which is the core equipment of the all slime cyanidation.Pictured left is a panorama of desorption electrolysis system.Anions that can be easily adsorbed by activated carbon have been put into the desorption system to displace Au(CN)2- for the desorption of gold.Rich liquid from the desorption of loaded carbon can be recovered by ionization method to get solid gold.
Civil construction mainly includes factory building and equipment foundation construction.after the foundation construction work of thickening and leaching tank, the installation and construction of pipeline and electric instrument also should be finished.
Field personnel of Xinhai in the project should pay more attention to sunscreen and mosquito bites, thus they has to wrap themselves in the unbearably hot day.
Subsection hoisting leaching tank. Equipment like leaching tank and thickening belongs to thin-walled tank,to protect the deformation of non-standard equipment,the larger-diameter tanks will manufacture in China,and install at the project site.For smaller-diameter tanks,professional hangers will be used in the hoisting work.
