Global mining industries is in its downturn during the past two years, while for some mining enterprises, market downturn is an opportunity, they optimizing operational and management ability, increasing technology investment. Shandong Xinhai Mining Technology & Equipment Inc. also carrying out a comprehensive reform, uplifting technology ability, actively exploring overseas marketing, upstream while the whole marketing is downturn. Sudan Project is a successful case of Xinhai exploring foreign market depending on the profound technology ability.
Xinhai gold EPC project in Sudan, covered mining & beneficiation and combined the solution of gravity separation and CIP, processing minerals for 500t/d, which received a high recovery rate of 92.5%. The gold output can reach 37,000 Ounce per year in forecast, the sales revenue can get $ 41 million , and the profits reached $ 14 million. Sudan contract was signed on July 15, 2014, the whole project was finished and been put into operation on June 25, 2015. The perfect completion of Sudan project shows the incomparable superiority of Xinhai EPC, which is short time limit, clearly-determined responsibility and benefit guaranteed. Xinhai erected its banner on the Africa continents time and time again, which is an hornor of Xinhai as well as mining workers of China.
Clients of Sudan project paid a special visit to Xinhai on Jan 18, 2014, for detailed communication with the Xinhai technicians. They made an estimate of the size , investment as well as earnings of the mill plant. During this meeting, based on rich experience of mineral processing and mill plant, Xinhai technicians wined the clients trusts for answering clients questions.
After the contract was signed, Clients posted to Xinhai two packages of samples, totally weight 400kg. Xinhai Mineral Processing Institute provided comprehensive mineral processing test after precious test.
The mineral processing test made an analysis to the gold content which is 4.31g/t, thus Xinhai technicians decided to recovery gold directly through the solution of CIP cyaniding, which including grinding the raw ore to 88.0% -200mush,and using lime as alkali, then adding sodium cyanide, agitating then leaching.The pulp density can reach 40%, 4kg/t of slime, 2kg/t sodium cyanide, the leaching rate of gold can get 91.45% which is perfectly good.While it was worth mentioning that the Institute noticed that if adding gravity separation, the recovery rate will not notably improved while increased the mineral processing cost. For the benefits of the customers, Xinhai technicians suggested cyaniding directly, while the customers firmly believed that with the deepen exploiting, the gold grade can increase to 8g/t, and considering finding large particles around the mine, technicians decided to adopt the solution of gravity separation + cyaniding the tailings after gravity separation.
Mine design, an vital part of Xinhai mineral processing EPC, was in charge of Xinhai Mining Design Institute with Class A Certification. For better suiting the actual situation of the project, technicians of the Mining Design Institute made field survey to the surroundings such as terrains, waters and power supply, then designed the construction drawing elaborately and gave 3D simulation based on the processing flowchart and the equipment selection mine processing test provided.
Equipment manufacturing usually keep abreast of the mine design.Xinhai Mining Machinery Manufacture made the equipment manufacture and purchasing according to the requirement of the mine test report.
After the Equipment manufacturing and purchasing, the perfect packaging and delivery system can guarantee the security service.
Xinhai Installation & Commissioning Operation Center Project No.1 was in charge of as well as full participation the field installation & commissioning. On the one hand, they supervised the construction site to inspect any problems, on the other hand , they optimized the production and management process to improve interests for customers.
Under the joint effort of the professional technicians-Project manager,mechanical technicians and preparation engineers, the installation & commissioning ahead of time of 20 days, and passed the test run and acceptance of work at once.
Illustrated product manuals and training handbooks was compiled to help Sudan worker for better familiar with the works.and Xinhai technicians made theory and field operation training to help customers quickly built up his own technician team , thus ensure the mineral processing entered into the stable operation period ahead of time.
Xinhai Sudan project passed the commissioning indicators at once after the rigorous installation & commissioning of Xinhai technicians.The acceptance rate reached 100%, 100% works fine,and the recovery rate reach 92.5%.Though the acceptance standard is in accordance with the European project standard which is more rigid, Xinhai passed the project acceptance at once in a high standard.Thus Sudan customers specially sent Xinhai written testimonials for commending the high project quality.
