Vietnam Kra 800tpd graphite ore dressing plant project was finished, which is one of our successful projects. Xinhai Design & Research Institute undertook the task of its graphite ore beneficiability test. According to the test report, technical staff designed flotation process of two stages one close-circuit crushing, one stage one-circuit grinding and classification, one roughing- two scavenging-ten cleaning.
Through the mineral processing test before beneficiation, technical staff of Xinhai made the conclusion that the graphite had great wash ability, so that the commonly used flotation process, characterized by simple reagents system also, was advanced and reliable beneficiation index, which could create huge economic and social profits, and it was well received by partners.
The test was mainly for the recycle of graphite mineral. The sample for test was prepared and sent by client. The raw ore would be ground first, and then after one roughing- two scavenging-ten cleaning, the test would finally receive output 14.2% , fixed carbon content 92.30%, the recovery rate 87.91%. In order to get some of high-carbon graphite, the graphite concentrate would be into wet screening, then the +140mm concentrate output 3.68%, fixed carbon content 95%; -140mm concentrate output 10.72%, fixed carbon content 91.46%.

Related equipment were set up, so the engineers teem was doing installation and commission.
INSTALLATION
Related equipment were set up, so the engineers teem was doing installation and commission.
COMMISSION
In order to help workers to be familiar with their works as soon as possible, Xinhai technicist did practical operation training for them, and helped workers pay attention to some details which was usually uneasy to be noticed but extremely important．It could build their own technical team and lay the foundation for the stable operation later.
TRAINING
Vietnam Kra 800tpd graphite ore beneficiation plant project finally got the recovery rate 92%. Prospective earnings was 48 million dollars. Xinhai provided one-stop service for this project, including mineral testing, engineer design, equipment manufacture, installation & commissioning and local training and designed capacity reached. Xinhai is focused on providing the most professional mineral equipment and solution for clients.
